In Reply to: Can I reprogram the keyless entry system myself? posted by Verdi on May 23, 19100 at 03:01:28:
Yes you can, I have included a copy of how to do it from SI2000. A paper clip works great as a jumper wire.
This should work for all 95 to 99 Suburbans, Tahoes, and Yukons. At the top of the page is a picture of DLC and what pins need to be grounded. Hope this helps.
Note: You do NOT have to have the keys in the ignition for this to work.
Transmitter Programming
When reprogramming the remote control door lock reciever, All transmitters must be programmed at this time in
order for the transmitters to operate the vehicle. Transmitters not programed at this time will not work and the
procedure will have to be redone with all the transmitters.
1.Ground pin 4 to pin 8 of the data link connector (DLC). The receiver will respond by locking and unlocking
the doors, and activating the liftgate window release (if equipped) within 2 seconds.
2.Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed
until the locks cycle (approximately 10 seconds).
3.Repeat step 2 for up to four total transmitters to be programmed (if available). The receiver will respond by
locking and unlocking the doors and activating the liftgate window release (if equipped) within 2 seconds.
4.Remove the ground applied to the DLC.
5.Lock and unlock the doors in order to verify the transmitter operation.
6.Activate the rear window release in order to verify the transmitter operation.
