Hey,

I was just wondering if anyone could give me the procedure for programing a keyless remote for a 2002 Trailblazer? Thanks !

Follow this link - Chevy owners. A quick registration and you can get access to the owners manual for your vehicle which has the steps for programing your remote.

Hope this helps...Jim

Thanks for the reply, but the owners manual does not help. they do not give a procedure for the programming. I got the procedure for the Silverado, and tried that, but that does not work. Can anyone help?????????

Picked this up from another board for trailblazer remote programming...Gotta love Google searches. Jim

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.

Thank you very much. I had tried this same procedure but with the drivers door open. I will try it with the door closed. Again Thank you very much.

jherdt,

I tried this tonight but could not get the remote to work. Is there anything else I can try?????

Sorry, that was the extent of the information I was able to find. The only other idea I have is to call the GM support line or maybe the dealer knows the drill.

Good Luck...Jim
