My wife went to the store today and locked the doors from the drive side lock button. When she returned she unlocked the passenger side door with the key, (remote we had died, and no longer works). and the alarm went off. She put the key on the ignition to see if it would go off, and it did not. She closed the door and went to the driver side door and locked it again and then unlocked it and the horn went off again when she opened the door. The car started and then died when horn was going off. Now the key will not unlock the doors from the outside using the key, but will lock the doors. The interior door switch will lock the doors, but will not unlock any of the doors either. Please help as my car is stranded with no other transportation. Thank you
Put new battery in your transmitter and try this process.... Transmitter Programming If you lose a transmitter, program the old and new transmitter(s) into the remote control door lock receiver's memory. Up to 4 transmitters may be programmed. Important Once the remote control door lock receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information, requiring the programming of all transmitters. Program only 1 vehicle remote control door lock receiver at a time. If more than 1 receiver is being programmed at the same time, it is possible that the same transmitter could be programmed to more than 1 remote control door lock receiver Perform the following steps in order to program the transmitter: Remove the ignition key from the ignition lock cylinder. Remove the BCM PRGRM fuse from the fuse panel. Refer to Electrical Center Identification Views in Wiring Systems. Close all of the doors. Close the liftgate. Turn the ignition lock cylinder to ACC. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second. Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode. Important After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds. Repeat the previous step on each additional transmitter to be programmed. Remove the ignition key from the ignition lock cylinder. Install the BCM PRGRM fuse back into the fuse panel. Refer to Electrical Center Identification Views in Wiring Systems. -------------------------------------------------------------------------------- Document ID# 475561 1998 Pontiac Trans Sport
Thanks for the plethora of information, but the issue is not the transmitter. The transmitter is dead and has been for years. That is not the issue. The issue is the key in the exterior lock will not unlock the doors anymore, nor will the lock switch on the interior door panel unlock the doors. They will lock the doors, but no unlock activity from the exterior key in the door or interior switch.
Sounds like a problem with the anti-theft module in the steering column. Your Transport uses a transponder key. The key is part of the GMs PASSKEY security system. If, for whatever reason, the vehicle doesn't recognize the key you're trying to use the alarm goes off and the vehicle shuts down. Unfortunately you'll have to have it towed to a GM dealer for repair. If you can find a reputable locksmith, familiar with the PASSKEY system, they may be able to fix it as well. One thing that might work, if you have another key, is use the spare key and start the engine. Then shut off the engine and immediately insert the key that now won't work. Turn the ignition to the run position but do not try to start the engine. Watch the security light on the dash. When it goes off turn the ignition off. Now try to start the engine. This is the procedure to program new keys to the vehicle. But, for it to work, you must already have a working key. HTH. -Jim
