Put key remote near the ignition switch. Disconnect the battery for 30 minutes and reconnect. It SHOULD reset the chip in the ignition to match the remote and they should then be recognised by the ECM.
Hello, To answer your question about programming a keyless entry remote you need a scanner tool that has the capability to accomplish this task. A GM Tech 2 or something else that has the ability to do what the Tech 2 does. I know this is not what you want to hear but I am reading it right out of the Cadillac Service Manual. Thank you
Try reprogramming the remotes. Here are the instructions for the procedure. Hope it helps. Cobra!
NOTE: All keyless entry remote transmitters (15K601) must be
programmed at the same time. NOTE: To program (or reprogram) the keyless entry remote transmitters
into the RAP module, perform the following steps:
Make sure that the anti-theft system is not armed or triggered.
Turn the ignition switch (11572) from OFF to RUN eight times within ten
seconds, ending in RUN. If the RAP module has successfully entered program mode,
it will lock and then unlock all doors.
Within 20 seconds, press any button on a keyless entry remote transmitter,
and the doors will lock and then unlock to confirm that each keyless entry
remote transmitter has been programmed. Repeat this step for each
If the door locks do not respond for any keyless entry remote transmitter,
wait several seconds and press the button again. If the door locks still fail to
respond, refer to Inspection and Verification.
Turn the ignition switch to the OFF position, or wait up to 20 seconds after
step 2, to exit program mode. If a keyless entry remote transmitter has been
programmed (or reprogrammed), the RAP module will lock and unlock all doors one
last time to confirm.
if its factory keyless entry, chances are your battery for your remote need to be replaced, the remote could also need to be reprogrammed... If it is an after-market system, there are several possibilities... wires could be pinched, the door lock solenoids could be broken or misaligned, the "brain" of the system might need to be reprogrammed.
try reprogramming the seats had to do this on an infiniti. look in the owners manual for the seat adjustments and it should tell you how to reprogram the auto seat. on this one i had to open the door more than two times turn key to on position not started set the seats and everything where it needed to be and resave it on the door switch. then the seat starting working right again.
It needs reprogrammed at a GM dealership...Personally, I'd find a car alarm installation shop and get a NEW "keyless entry" for around $89...probably the same amount the dealer will charge you! Good Luck
