Remote Keyless Entry

[AnsteyZ71]

Does anyone know how to program a remote? I was wondering if I should go buy a after market Remote Keyless Entry or if my old one can be reprogrammed. I have a 2004 Colorado and when I bought it used there wasn't a remote. I tracked down one for that model but was wonding if I should buy it and have it programmed.

Any and all info is much appreciated.

I looked into it a little bit. It looks like it has to be programmed by the dealer. ???

Not sure about Collie, Steve. but here is repost intructions...

Transmitter Programming

Important
All transmitters which are to be recognized by the Liftgate Module (LGM) 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.


You may program up to 4 transmitters, using either of the 2 following procedures:

Method 1 - No Tools Required
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.
Method 2 - Scan Tool Required
Install a scan tool.
Turn the ignition ON, with the engine OFF.
Use the scan tool in order to access the Lift Gate Module (LGM) Special Function: Program Key Fobs menu.
Follow the directions on the scan tool in order to program the transmitters.
Operate the transmitter functions in order to verify correct system operation.

I bought a new remote to replace one i lost on my 2004 and the dealer had to plug the tech II (some machine) into it and program it, said for that model it was the only way to do it. They did it for free though. Oh and I had to have both with me reprogramed because when one gets programed it changed the code so the others wouldn't work.

Who was the dealer? Most charge you for it.

Now the dealers are coming around to programming it for free if you buy the remote from them. That's why the remotes went up in price. I remember when they were around $30 and you could program it yourself.
