Key Fob Works but Passive Keyless Entry Doesn’t? Why Your Car Won’t Unlock When You Touch the Door Handle in Orange County
You walk up to your car with the smart key in your pocket, grab the driver's door handle, and expect the vehicle to unlock automatically.
Nothing happens.
You grab the handle again.
Still locked.
So you take the key fob out of your pocket and press UNLOCK.
The doors open immediately.
You get inside, press the brake and START button, and the vehicle starts normally.
Now the problem becomes much more specific:
REMOTE UNLOCK ✓PUSH-TO-START ✓PASSIVE DOOR ENTRY ✕
When keyless entry is not working but the key fob works, it does not automatically mean the entire smart key needs replacement or programming.
The issue could involve the key-fob battery, proximity detection, where the key is being carried, a particular door handle or sensor, vehicle settings, previous key damage, vehicle power, or another part of the vehicle's passive-entry system.
For Orange County drivers searching for keyless entry repair near me, key fob replacement near me, smart key replacement near me, key fob programming near me, or an automotive locksmith near me, the first goal should be diagnosis—not automatically buying another key.
Here's how to narrow down the problem.
1. First, Understand What “Keyless Entry” Means
The phrase keyless entry can describe several different vehicle features.
That creates confusion when troubleshooting.
A modern smart key may provide:
Remote LOCK
Remote UNLOCK
Trunk or liftgate release
Passive/proximity door entry
Push-to-start authorization
Passive trunk access
Emergency mechanical-key access
These functions are related, but they are not necessarily identical.
Your key can therefore behave like this:
REMOTE LOCK ✓REMOTE UNLOCK ✓PUSH-TO-START ✓PASSIVE ENTRY ✕
The key is obviously not completely dead.
The specific failure is that the vehicle is not unlocking as expected when you approach or interact with the applicable door handle while carrying the smart key.
2. Remote Keyless Entry and Passive Entry Are Different
This distinction is important.
Remote Keyless Entry
You physically press a button on the fob:
Press UNLOCK → Doors unlock
Passive Keyless Entry
You carry the smart key without pressing its buttons.
Depending on the vehicle, approaching or touching/grabbing an equipped door handle allows the vehicle to detect the authorized key and unlock.
So when someone says:
“My keyless entry isn't working.”
the next question should be:
Does the remote UNLOCK button still work?
If yes, the problem is more specific than a completely nonfunctional remote.
3. Push-to-Start Is Another Useful Comparison
Now test whether the vehicle starts normally.
Suppose:
Remote UNLOCK ✓
Passive Entry ✕
Push-to-Start ✓
That pattern provides useful information.
The vehicle still recognizes the key sufficiently for starting under normal conditions, but passive door access is not behaving as expected.
Now compare:
Remote UNLOCK ✓
Passive Entry ✕
Push-to-Start ✕
The problem may be broader than a door-handle entry issue.
If your dashboard displays a key-recognition warning, our guide on Push-to-Start Says “Key Not Detected”? covers that symptom separately.
4. Confirm That the Vehicle Actually Has Passive Entry on That Door
Before troubleshooting a “broken” feature, confirm that the specific vehicle and door are equipped to provide it.
Not every vehicle with a push-button start necessarily provides passive entry on every door.
Depending on the model and trim, passive entry may be available on:
Driver's door only
Both front doors
Selected doors
Trunk or liftgate
Different combinations
Vehicle configurations vary.
Check the owner's manual or vehicle-specific documentation instead of assuming every door handle should behave the same way.
5. Start With the Driver's Door
Use the door you normally enter through.
Keep the smart key with you and test the driver's handle according to the manufacturer's normal procedure.
Observe:
Does the vehicle unlock?
Does it beep?
Do the lights flash?
Does nothing happen?
Does it work after several attempts?
Does it work only when the key is removed from your pocket?
Document the exact behavior.
A repeatable pattern is more useful than simply saying:
“Sometimes the handle doesn't work.”
6. Test the Passenger Door Separately
If the vehicle has passive entry on the passenger side, compare it with the driver's door.
Pattern A
Driver Handle ✕Passenger Handle ✓
This is important.
The smart key can clearly participate in passive entry through at least one equipped location.
Replacing the entire fob may not be the logical first step.
Pattern B
Driver Handle ✕Passenger Handle ✕
Now the problem is broader.
Continue testing the key, spare key, vehicle settings, and other smart-key functions.
7. One Bad Door Handle Can Look Like a Bad Smart Key
Imagine an Orange County driver uses only the driver's door.
That handle stops responding to passive entry.
The driver concludes:
“My proximity key is broken.”
But then the passenger-side equipped handle unlocks the car normally.
That changes the diagnosis significantly.
If only one equipped door consistently fails with multiple authorized keys, the vehicle-side handle/sensor system deserves attention before buying another car key fob replacement Orange County.
8. Check Passive Trunk or Liftgate Access Where Applicable
Some vehicles provide smart-key detection at the trunk or liftgate.
If yours does, test it according to the manufacturer's procedure.
You might discover:
Driver passive entry ✕Passenger passive entry ✕Passive trunk access ✕
versus:
Driver passive entry ✕Passenger passive entry ✓Passive trunk access ✓
The second pattern strongly suggests that the smart key is still being detected passively in other areas.
Again, that makes an immediate full key replacement less convincing.
9. Test the Remote Buttons at the Same Time
While passive entry is failing, test the fob's buttons.
Try:
LOCK
UNLOCK
TRUNK, if equipped
For example:
LOCK ✓UNLOCK ✓TRUNK ✓PASSIVE ENTRY ✕
This confirms that the remote-control side remains functional.
Our broader article on Car Key Fob Buttons Not Working covers cases where individual remote buttons themselves fail.
Here, however, the main issue is different:
The buttons work—the hands-free/proximity entry does not.
10. Could the Key Fob Battery Cause Passive Entry Problems?
Yes, battery condition is worth checking.
A weakening smart-key battery may be associated with symptoms such as:
Reduced remote range
Intermittent proximity detection
Passive entry becoming unreliable
Multiple attempts needed
Push-to-start recognition issues
Low key-battery warning on applicable vehicles
Passive/proximity functions can make a weak battery noticeable even while some button-operated functions still work.
So don't rule out the battery simply because pressing UNLOCK still works.
11. Look for Other Weak-Battery Symptoms
Don't evaluate passive entry in isolation.
Ask:
Has remote range decreased?
Do buttons require multiple presses?
Does push-to-start occasionally hesitate?
Have you seen a low key-battery warning?
Does the fob work better when very close to the vehicle?
Suppose:
Remote range weak ⚠Passive entry intermittent ⚠Push-to-start detection occasionally weak ⚠
Battery condition becomes more interesting.
But suppose:
Remote range excellent ✓Push-to-start perfect ✓Passenger passive entry perfect ✓Driver handle passive entry ✕
That looks much less like a simple whole-fob battery problem.
12. What If the Key Fob Battery Keeps Dying?
Repeatedly replacing the coin-cell battery is not a normal long-term troubleshooting strategy.
If your fob drains batteries unusually quickly, the key itself may deserve further evaluation.
See our detailed guide on Car Key Fob Battery Keeps Dying.
A fresh battery may temporarily improve symptoms, but unusually rapid battery drain is its own issue.
13. What If You Already Replaced the Fob Battery?
Suppose passive entry stopped working.
You installed the correct fresh battery.
Now:
Remote buttons ✓Push-to-start ✓Passive entry ✕
At this point, continuously replacing batteries will probably not provide much additional information.
Check:
Battery orientation
Battery seating
Housing closure
Internal contact condition
Whether the problem started after opening the fob
If the remote developed broader problems immediately after battery replacement, see Key Fob Not Working After Battery Replacement.
14. Take the Key Out of Your Pocket
For a clean diagnostic test, hold the smart key normally in your hand.
Then try passive entry again.
Compare:
Key in Pocket
Passive entry ✕
Key in Hand
Passive entry ✓
If this pattern repeats, note it.
Do not immediately conclude exactly why it happens, but the difference is useful.
If passive entry still fails with the key held normally near the appropriate door, continue troubleshooting.
15. Remove the Key From a Crowded Bag
Smart keys often end up inside:
Handbags
Backpacks
Laptop bags
Gym bags
Beach bags
For diagnosis, remove the key and test it by itself.
Compare:
Inside bag → Passive entry unreliable
Key alone → Passive entry normal
If the difference repeats consistently, tell the technician.
If the problem continues regardless of key position, the bag probably isn't the main explanation.
16. Don't Assume Every Nearby Object Is “Interference”
Online troubleshooting often blames every smart-key problem on interference.
Avoid jumping to conclusions.
Instead, test the pattern.
Does passive entry fail:
Everywhere?
Only at home?
Only at work?
Only in one parking garage?
Only when the key is inside a particular bag?
A repeatable location or situation can be useful diagnostic information.
But a one-time failure does not prove interference.
17. Does Passive Entry Fail Everywhere?
Try the system in several normal locations.
For example:
Huntington Beach Home
Passive entry ✕
Anaheim Workplace
Passive entry ✕
Santa Ana Parking Lot
Passive entry ✕
A problem that follows the vehicle and key across unrelated locations is less likely to be explained by one particular environment.
Now compare:
Home
Passive entry ✓
Work
Passive entry ✓
One specific location
Passive entry ✕
That pattern is worth documenting before replacing hardware.
18. Test the Spare Smart Key
If you have a second authorized smart key, this is one of the most useful tests.
Main Key
Remote buttons ✓Push-to-start ✓Passive entry ✕
Spare Key
Remote buttons ✓Push-to-start ✓Passive entry ✓
This strongly shifts attention toward the primary smart key.
Now consider:
Main Key
Passive entry ✕
Spare Key
Passive entry ✕
If two recently working authorized keys have the same passive-entry failure, investigate the shared vehicle side before buying two replacements.
19. The Spare-Key Test Can Prevent an Unnecessary Replacement
Suppose you're searching for smart key replacement near me because the driver's door no longer unlocks when you touch the handle.
Then you test your spare.
The spare produces the exact same failure.
Next you test the passenger handle.
It works with both keys.
Now the evidence has changed dramatically.
The issue appears tied more closely to one entry point than to one particular key.
A new smart key may not solve that problem.
20. Make Sure the Spare Key Is Dependable
A spare key sitting unused for years can have its own weak battery.
Before treating it as your diagnostic control, check whether it:
Locks remotely
Unlocks remotely
Starts the vehicle
Works for passive entry elsewhere
Has a reasonable battery condition
A neglected spare with its own problems can create misleading comparisons.
21. Did the Main Key Get Dropped?
Physical impact can matter even if the remote buttons continue working.
Think about whether the smart key recently:
Fell on concrete
Hit tile
Dropped in a parking lot
Was stepped on
Was crushed in a bag
After impact, you might see:
Remote buttons ✓Push-to-start ✓Passive detection intermittent ⚠
The key does not need to become completely dead for physical damage to be relevant.
See Car Key Fob Won't Work After Being Dropped.
22. Was the Smart Key Exposed to Water?
Orange County's coastal lifestyle creates plenty of opportunities for key-fob moisture exposure.
Examples include:
Beach trips
Pool areas
Rain
Wet towels
Spilled drinks
Damp gym bags
Washing machines
A wet key can develop inconsistent electronic behavior rather than immediate total failure.
If passive entry problems started after moisture exposure, tell the technician.
Our Car Key Fob Got Wet guide covers this situation separately.
23. Inspect the Smart Key Housing
Look carefully at the fob.
Check for:
Cracks
Loose shell
Gaps between housing halves
Broken clips
Loose battery cover
Signs it was previously opened
Internal movement when shaken gently
Other physical damage
A compromised housing can expose the electronics to impact, moisture, and poor battery contact.
If the key's physical condition has deteriorated alongside passive-entry reliability, that history matters.
24. What If Remote Range Is Also Getting Worse?
Suppose passive entry isn't your only symptom.
You also notice:
Remote used to work from 30 feet
but now:
Remote works only beside the vehicle
That suggests a broader key-fob performance issue.
See Car Key Fob Has No Range? for that symptom.
By contrast:
Remote range normal ✓Push-to-start normal ✓Only one passive-entry handle ✕
points in a different direction.
25. What If Push-to-Start Recognition Is Also Intermittent?
Now the issue is broader than door-handle entry.
For example:
Remote buttons ✓
Passive entry intermittent ⚠
Push-to-start detection intermittent ⚠
That pattern may involve overall smart-key recognition rather than one particular handle.
Our guide on intermittent smart-key detection covers this exact broader symptom.
The key distinction is:
This Article
Passive door entry fails while other smart-key functions remain normal.
Broader Detection Problem
Multiple proximity-based functions become intermittent.
Keeping these intents separate prevents unnecessary assumptions.
26. Check Vehicle Settings
Some vehicles allow passive-entry or door-unlocking behavior to be configured.
Depending on the vehicle, settings may affect things such as:
Which doors unlock
Driver-only versus all-door unlocking
Passive-entry behavior
Walk-away locking
Touch-sensor operation
Keyless access features
If the problem began after:
Vehicle service
Battery disconnection
Software changes
Driver-profile changes
Someone adjusted vehicle settings
check the vehicle-specific settings and owner's documentation.
Do not assume the key is broken until you confirm the feature is still enabled and configured as expected.
27. Did the Problem Begin After the Vehicle Battery Was Replaced?
Pay attention to timing.
If passive entry changed immediately after the vehicle's 12V battery was:
Replaced
Disconnected
Jump-started
Allowed to become deeply discharged
note that history.
It does not automatically prove the battery work caused the smart-key problem, but the timing matters.
If multiple key functions changed after vehicle battery replacement, see Key Fob Not Working After Car Battery Replacement.
28. Don't Confuse the Vehicle Battery With the Fob Battery
There are two completely different batteries involved.
Smart-Key Battery
Small battery inside the key fob.
Vehicle 12V Battery
Main electrical battery supplying the vehicle.
Replacing one does not replace the other.
When calling a mobile automotive locksmith Orange County service, be specific about which battery was changed.
29. Test Whether Only One Door Is Affected
This is one of the most important vehicle-side tests.
Suppose your vehicle supports passive entry at both front doors.
Test:
Driver Handle → ✕
Passenger Handle → ✓
Then test both with the spare key:
Driver Handle → ✕
Passenger Handle → ✓
This is powerful evidence.
Two independent keys show the same failure at one specific equipped door.
Before paying for key fob programming near me or another smart key, the vehicle-side door-handle system deserves attention.
30. What If Every Passive-Entry Point Fails?
Now consider:
Driver Handle ✕
Passenger Handle ✕
Passive Trunk Access ✕
with:
Remote Buttons ✓
Push-to-Start ✓
This is a broader passive-entry failure.
At this point, useful comparisons include:
Main key vs spare
Vehicle settings
Fob battery condition
Recent vehicle battery history
Whether passive entry ever works
Whether the problem is location-specific
Avoid immediately deciding that one specific component has failed.
31. Does the Vehicle React When You Touch the Handle?
Observe carefully.
When you use the equipped handle:
Does it beep?
Do lights flash?
Do locks move?
Does it unlock and immediately relock?
Is there no response at all?
A partial response can be useful.
For example:
Handle touched → Vehicle beeps
but:
Door remains locked
is different from:
Handle touched → Nothing
Describe that behavior accurately when requesting service.
32. Don't Replace the Smart Key to Repair a Door Handle Sensor
+
This deserves to be stated clearly.
If:
Main Key → Passenger passive entry ✓
Spare Key → Passenger passive entry ✓
but:
Main Key → Driver passive entry ✕
Spare Key → Driver passive entry ✕
then replacing the main key does not logically address the common failure at the driver's handle.
A car key fob replacement Orange County service is appropriate when the key needs replacement.
It is not a universal repair for every keyless-entry problem on the vehicle
33. Does Passive Entry Failure Mean the Key Needs
Programming?
Not automatically.
Programming cannot physically repair:
A damaged door-handle sensor
Vehicle wiring
Vehicle antenna problems
Cracked key electronics
Poor battery contact
Water damage
Weak vehicle battery
If the smart key still starts the vehicle and operates remote functions, do not assume a random “reprogram” will restore one failed passive-entry location.
Programming becomes relevant when the specific key/vehicle situation actually requires it.
For more information, see Car Key Programming Near Me in Orange County.
34. Avoid Random Online Reprogramming Procedures
You may find videos telling you to:
Press LOCK and UNLOCK together
Cycle the ignition
Disconnect the car battery
Open and close the driver's door repeatedly
Perform a button sequence
Some vehicle-specific procedures exist.
That does not mean a random procedure applies to your vehicle or to a passive-entry sensor problem.
Do not confuse diagnosis with experimentation.
35. Huntington Beach Scenario: Main Key Fails, Spare Works
A Huntington Beach driver notices:
Main Key
Remote UNLOCK ✓Push-to-start ✓Passive entry ✕
Spare Key
Remote UNLOCK ✓Push-to-start ✓Passive entry ✓
The passenger and driver handles both work normally with the spare.
This pattern strongly shifts attention toward the primary smart key.
Key battery, physical condition, electronics, repair feasibility, and replacement options can then be evaluated.
36. Anaheim Scenario: Driver Handle Fails With Both Keys
An Anaheim driver has two good smart keys.
Both produce:
Driver Handle ✕
Passenger Handle ✓
Push-to-Start ✓
The common failure is the driver's passive-entry point.
Replacing two keys would be difficult to justify based on this pattern.
Vehicle-side diagnosis becomes more appropriate.
37. Santa Ana Scenario: Passive Entry and Start Detection Both Become Weak
A Santa Ana driver notices:
Remote UNLOCK ✓
Passive Entry → intermittent
Push-to-Start Detection → intermittent
The problem is no longer limited to one door handle.
The broader smart-key recognition pattern deserves investigation.
If your vehicle recognizes the key only sometimes, that is different from a single passive-entry location failing.
38. Westminster Scenario: New Fob Battery Helps but Doesn't Fully Fix It
A Westminster driver replaces an aging fob battery.
Before:
Remote range weak
Passive entry almost never works
After:
Remote range normal ✓
Passive entry improves but remains intermittent ⚠
The battery clearly affected performance, but another issue may remain.
This is why replacing a battery can be useful without necessarily completing the diagnosis.
39. Buena Park Scenario: Feature Was Disabled
A Buena Park driver assumes the smart key has failed because passive entry no longer works.
Remote UNLOCK and push-to-start are perfect.
After reviewing the vehicle's settings and owner's information, the driver discovers the relevant keyless-access behavior had been changed.
No replacement smart key was required.
This is why settings should be checked before purchasing hardware.
40. Garden Grove Scenario: Key Works Everywhere Except Driver's Door
A Garden Grove driver tests:
Driver Handle ✕
Passenger Handle ✓
Trunk Passive Access ✓
Remote Buttons ✓
Push-to-Start ✓
The spare produces the same pattern.
This is one of the clearest examples of why a smart key door handle not unlocking does not always mean the smart key itself is bad.
41. When Should You Contact an Automotive Locksmith?
An automotive locksmith near me may be useful when evidence points toward the key or an applicable automotive key service.
Examples include:
Main key passive entry fails while spare works
Fob battery/contact condition needs evaluation
Smart key has physical damage
Key was dropped or exposed to moisture
Multiple key functions are deteriorating
Replacement smart key is needed
Compatible replacement requires applicable programming
Transponder/smart-key programming is required
You need a spare key
Automotive key cutting is required
For supported vehicles, Mobile Car Key Service provides applicable mobile automotive key services throughout Orange County, California.
If testing points instead toward a vehicle door-handle sensor or another vehicle-side system, that issue may require the appropriate vehicle repair specialist.
42. What Should You Tell the Locksmith?
When searching for a mobile car locksmith near me, have these details ready:
Vehicle year
Make
Model
Push-to-start or keyed ignition
Key type
Whether remote LOCK works
Whether remote UNLOCK works
Whether push-to-start works
Which passive-entry doors fail
Whether passenger-side entry works
Whether passive trunk access works
Whether the spare behaves differently
Whether the fob battery was changed
Whether the key was dropped
Whether it became wet
Whether the vehicle battery was recently replaced
Whether vehicle settings were changed
Instead of saying:
“My keyless entry is broken,”
say:
“The remote unlocks and the car starts normally, but passive entry doesn't work at the driver's handle. My spare key does the same thing, while the passenger handle works.”
That description is much more useful.

44. Diagnose the Pattern Before Buying a Replacement Key
The most important distinction in this problem is:
Key-Specific Pattern
MAIN KEY PASSIVE ENTRY ✕SPARE KEY PASSIVE ENTRY ✓VEHICLE STARTS NORMALLY ✓
The main smart key deserves closer evaluation.
Door-Specific Pattern
MAIN KEY — DRIVER HANDLE ✕ / PASSENGER ✓SPARE KEY — DRIVER HANDLE ✕ / PASSENGER ✓
The driver's passive-entry point deserves vehicle-side attention.
Broader Smart-Key Pattern
PASSIVE ENTRY ⚠PUSH-TO-START DETECTION ⚠REMOTE RANGE ⚠
The problem may involve broader key or smart-key recognition rather than one door handle.
This diagnostic approach matters for Orange County drivers searching for keyless entry not working but key fob works, passive keyless entry not working, car door handle keyless entry not working, smart key door handle not unlocking, proximity key not unlocking car, keyless entry repair near me, key fob replacement near me, smart key replacement near me, car key fob replacement Orange County, key fob programming near me, car key programming near me, smart key programming Orange County, automotive locksmith near me, mobile automotive locksmith Orange County, mobile car locksmith near me, car locksmith Orange County, replacement car key near me, spare car key near me, transponder key programming near me, and car key replacement Orange County.

Frequently Asked Questions
1. Why is my keyless entry not working even though my key fob works?
Remote buttons and passive/proximity entry are different functions. If the remote still locks and unlocks the vehicle but touching an equipped door handle does not, the issue may involve key battery condition, the smart key, vehicle settings, a specific door-handle entry point, or another part of the vehicle's passive-entry system.
2. Why does my key fob unlock the car with the button but not from the door handle?
The remote UNLOCK command can work while passive key detection at the door does not. Test other equipped doors and a dependable spare key to determine whether the failure follows the key or one particular vehicle entry point.
3. Can a weak key fob battery cause passive keyless entry to stop working?
A weak fob battery may contribute to reduced range or unreliable proximity functions on some vehicles. If a correct fresh battery does not solve the issue, further diagnosis may be needed.
4. Why does passive entry work on the passenger door but not the driver's door?
If the vehicle supports passive entry on both doors and multiple authorized keys work on the passenger side but fail at the driver's side, a vehicle-side issue at the driver's entry point becomes more relevant than replacing one particular key.
5. Why does my spare key work with passive entry but my main key doesn't?
If the spare works normally at the same doors while the main key consistently fails, the main key becomes the stronger suspect. Its battery, physical condition, electronics, or replacement needs may deserve evaluation.
6. Why do both of my smart keys fail passive entry?
If two recently working authorized keys develop the same passive-entry problem, common vehicle-side factors such as settings, power conditions, or the applicable passive-entry system should be considered before replacing both keys.
7. Can dropping my smart key stop passive entry from working?
Yes. Physical impact may affect the housing, battery contact, or internal electronics without necessarily disabling every remote function.
8. Can water damage cause passive keyless entry problems?
Yes. Moisture can cause inconsistent electronic behavior. A water-exposed smart key may continue performing some functions while other proximity-related functions become unreliable.
9. Does my smart key need programming if passive entry doesn't work?
Not automatically. Programming cannot repair a vehicle-side door-handle issue, damaged key hardware, weak vehicle battery, or physical electronic damage. Programming is relevant when the specific key and vehicle situation requires it.
10. Can an automotive locksmith replace a smart key with passive-entry problems?
For many supported vehicles, an automotive locksmith may be able to provide an appropriate replacement smart key and perform applicable programming and automotive key-cutting services when the key itself requires replacement.
11. Can a mobile locksmith program a replacement smart key at my location?
For supported vehicles and accessible locations, applicable smart-key, transponder-key, or key-fob programming may be performed at the vehicle.
12. How much does smart key replacement cost in Orange County?
Cost depends on the vehicle year, make, model, smart-key technology, replacement hardware, programming requirements, emergency blade, automotive key cutting, available working keys, and mobile-service requirements.
13. Should I replace my smart key if only passive entry doesn't work?
Not automatically. Compare the main key with a dependable spare and test different equipped entry points. If only one key fails everywhere while the spare works normally, key-specific evaluation becomes more reasonable.
14. Should I buy a new key if both keys fail at the same door handle?
Not as the first assumption. If both authorized keys work at other equipped doors but fail at the same specific handle, vehicle-side diagnosis of that entry point may be more appropriate.
15. Should I make a spare key if my only smart key is becoming unreliable?
A dependable spare provides backup and gives you a second authorized key for distinguishing key-specific symptoms from vehicle-side problems.
Don't Replace the Key Until You Know Which Side Is Failing
The most important takeaway is simple.
If:
REMOTE UNLOCK ✓PUSH-TO-START ✓PASSIVE ENTRY ✕
your smart key is not completely dead.
Now compare the key and vehicle.
If the Problem Follows One Key
MAIN KEY ✕SPARE KEY ✓
Evaluate the main key.
If the Problem Follows One Door
MAIN KEY: DRIVER ✕ / PASSENGER ✓SPARE KEY: DRIVER ✕ / PASSENGER ✓
Investigate the vehicle-side entry point.
If Multiple Proximity Functions Fail
PASSIVE ENTRY ⚠PUSH-TO-START DETECTION ⚠
Investigate the broader smart-key recognition problem.
