Rdebison is correct. This is caused by a firmware bug in the body control module (BCM). Have your dealer perform Chrysler Service Bulletin 08-040-04. It describe the symptoms, the affected firmware versions, and the upgrade process. We bought our 2005 T&C new, and the bug took over 3 years to show up. The firmware upgrade fixed it.

How do I remove auto door locks


  1. Put the key in the ignition and turn it to on.
  2. Press the Unlock button three times.
  3. Turn the ignition off.
  4. Press the Unlock button three more times.
  5. Turn the ignition back to on.
  6. The horn should beep once. This tells you that you're now in programming mode.
  7. Press the Unlock button, then press Lock again. The horn will beep once to tell you that Auto Lock was deactivated. It will beep twice if you're reactivating the system
There are many ways, I'm not sure which one will work on your car. I answered the two ways. I hope it works.

1. Open the driver's door and put the shifter in Park
2. Turn the ignition to On (II).
3. Press and hold the unlock side of the master lock switch for five seconds until you hear two clicks.
4. Within five seconds, turn the ignition to the Lock position.

it's in owner manual. But, first you have to enter your original code and it must work. then you press the 1 button and then enter a new 5 digit code, then press the 1 button again.

Keyless Entry Keypad To unlock the driver front door (20124) , and disarm the anti-theft alarm control (19A366) , (if equipped):

    Programming instructions for keyless remote Does anyone have the programming instructions for 1998 honda passport keyless remote (FCC #HYQ1512R)?


    Get into your passport and unlock all doors. Leave drivers door open. Put key into ignition. Turn to ON (not start), then OFF three times within 5 seconds. Close and open the drivers door twice. Turn key to ON then OFF 5 times within 5 seconds. Close then open the drivers door. Press either the lock or unlock button on the remote. Doors will lock then unlock. Press the button again. Doors will lock then unlock again. Close door to finish programming. If it doesnt work, try it again but turn the key faster. You have to do it all pretty quick, but I had it done on the second try.

    Jeep alarm will not turn off


    The ignition security on/off is located at the trunk lock. unlock and lock rear gate and the alarm will turn off. My jeep sat in my drive for a month before a jeep tech told me this. It still triggers the security sometimes when I unlock the passenger door with the key and I go straight to the rear gate lock and it shuts off instantly.
