I have access to a tech 2 and acquired a pdf of the manual online.. still cant figure it out.
Called all 3 dealers in town and they want a days worth of my wages to do what I assume takes 10 keystrokes.
The 2 manuals I have make no mention of programming remotes...
Can anyone who has done it before give me some hints? Thanks for any help!!
This is from GM's 1999 book. It should be the same.
Important! Once the BCM enters program mode, all transmitters must be programmed at the same time. Any transmitters not learned at this time will be erased.
1) Remove the key from the ignition cylinder
2) Remove the BCM PRGRM fuse from the fuse panel
3) Close all the doors
4) Close the liftgate
5) Turn the ign lock cylinder to the ACC. position
6) Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second
7) Open and close any door
A chime will be heard when the system enters the BCM programming 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.
8) Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds
9) Repeat the previous step on each additional transmitter to be programmed.
10) Remove the ignition key from the ignition cylinder
11) Install the BCM PRGRM fuse back into the fuse panel.
Also Found this on another site for GTO, Not sure if it would be the same for a cavalier but worth a shot :
The transmitter may not communicate with the receiver if any of the following situations occurs:
"The transmitter battery wears down.
The transmitter key has been replaced.
The Body Control Module (BCM) has been replaced.
Perform the synchronizing procedure if the transmitter does not communicate with the receiver. If the transmitter and/or receiver are replaced, preform the following programming procedure:
Programming Transmitters With Tech 2
Important
It is not possible to program a remote transmitter without the Body Control Module (BCM) security code. The security code is contained on the Important Security Information Card issued with the vehicle when new.
Using the Tech 2, select Body / Programming / Program Remote Key and follow the instructions.
Enter the security code when prompted and follow the instructions.
Programming Transmitters Without Tech 2
Turn the ignition to ON, then wait 10 minutes for the next step in the programming sequence.
After the 10 minutes has elapsed, the car horn will chirp once. Turn the ignition switch to the OFF position within 5 minutes after the horn has sounded, then to the ON position within 5 seconds after switching it OFF.
Leave the key to the ON position for 10 minutes. After the 10 minutes has elapsed, the car horn will chirp twice. Turn the ignition switch to the OFF position within 5 minutes after the horn has sounded, then to the ON position within 5 seconds after switching it OFF.
Leave the key to the ON position for 10 minutes. After the 10 minutes has elapsed, the car horn will chirp 3 times.
Verify that the security indicator in the instrument cluster has stopped flashing and attempt to start the vehicle.
Turn the ignition to OFF and remove the key from the ignition switch.
Move approximately 3 meters (10 ft) away from the vehicle and test the transmitter functions to validate that the transmitter has been programmed successfully."
