2003 crown vic keyfob only works with ignition in run position .keyless entry and door locks work fine.even tried new keyfob.no change


The keyless entry system consists of the following components:
  • driver door module (DDM)
  • keyless entry transmitter
  • keyless entry keypad
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
  • Battery junction box (BJB) fuses:
    • circuit breaker 7 (20A)
  • Central junction box (CJB)
    • 4 (10A)
    • 6 (15A)
    • 8 (25A)
    • 13 (5A)
  • Keyless entry keypad switch
  • Power door lock actuator
  • Luggage compartment release switch
  • Luggage compartment release solenoid
  • Connectors or connections
  • Wiring harness
  • If fuse's good have checked for DTC'S - diagnostic trouble codes .
  • B1526 Keyless Entry Circuit Short to Ground DDM Go To Pinpoint Test E . B1553 Decklid Release Circuit Short to Battery DDM Go To Pinpoint Test B . B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .
  • The doors do not lock/unlock using the remote transmitter
  • Remote transmitter not programmed.
  • Remote transmitter.
  • DDM.
  • Go To Pinpoint Test F .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

2005 Nissan Sentra, the keyless entry locks the doors but does not unlock them.


does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck

My 2000 Lincoln LS keyless remote doesn't work, so I replaced the $15.89 battery and still nothing from what Ive read on this site keyless entry keypad remote code should be in the manual but...


You have to go to a lincoln dealer with your title
& Vin #,they will give you the factory code for the
Keyless Entry on the drivers door

Make sure you have them write down to proceedure
that was in the owners manual ,so you can change it
to what you want.

I have a 2004 LS I don't know if it is the same.
Have no way to scan it & send it to you

I have a 96 ford conversion van with a 600 plus addon keyless system and need to program new keyless remots , need to know how to get system in program mode.


Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

Keyless Remote 2008 RAV4


You can take it back to the dealer, and have them change the battery, or go to Autozone, buy the battery and do it yourself. They can show you how to do it. And which battery it takes. It's not hard to do. Good luck.

Keyless entry


I had the same exact problem and fixed it by disconnecting the battery for 5 minutes. I was also having a problem with the A/C compressor not kicking in and after the battery disconnect it is working fine.
