Keyless Entry for GMC 98 Yukon

[ech72]

I have a just purchased a 1998 GMC Yukon SLE and

the Keyless Entry is working, but not like it

should, you see if you hit the lock button twice

it is supposed to make the horn chirp as

confirmation of security system, but it does

not.The horn has been checked and is working

properly though. I have also checked fuses and

relays and I can't figure out what is the

problem, Can anyone help me with info on how to

fix this problem or how to reprogram my keyless

entry, before I decide to consult the dealership

with this issue.

I think this should answer both of your questions good luck!

Transmitter Programming Base
If they key is in the ON position during the programming procedure, the horn chirp will be disabled, if the key is in the OFF position, the horn chirp will be enabled. The horn will chirp when the lock button is pressed two times.


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.

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.
Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed until the locks cycle (approximately 10 seconds).
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.
Remove the ground applied to the DLC.
Lock and unlock the doors in order to verify the transmitter operation.
Activate the rear window release in order to verify the transmitter operation.
