I took it in to have a key fob programmed it couldn't program it and when they unplugged their machine it wouldn't start. But has power to the lights and turn signals. No power to the radio or heater and the starter will not turn over. I've had my mechanic look at it he has replaced the starter and it still won't turn over. I'm wondering if they have erase the memory in the key when they plug the machine up because they couldn't get it to program.

Hi,

Is the anti theft light staying on or flashing? Exactly what kind of machine was used to reprogram the key fob?

Here are the directions for programming the fob/key-less entry. Let me know if this is what was done.

Transmitter Programming

Important: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

1. Install a scan tool.
2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
3. Press the START soft key on the scan tool.

Important: The scan tool must stay connected until all of the transmitters are programmed.

4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.

Let me know.
