How do you program keyless entry remotes?

Answer 1

This is going to be a quick guide to save you from paying a programming fee for your remote keyless entry for All Yukon and Envoy, Tahoe and Trailblazer models.. This guide will not work for any other models, but will for most all Yukon, Tahoes, and Envoy, Trailblazers including XL and Denali models. If you go to a dealership, you will pay around $50 for programming!

This will work on new remotes you just purchased or on old remotes that you may have had batteries replaced that lost program. It must be followed exactly.

First, hold down the unlock feature on your door and keep it held down. While holding down, turn ignition key over 2 times and turn off (dont start vehicle). The speed at which you do this is not important, but just turn to where radio will play and instrument panel lights up. After you have done this the unlock-lock will cycle on your doors automatically and the horn will sound. Now, you can let go of the unlock on door and Hold the Lock and Unlock function on the remote, Both at same time! Hold for 15 to 20 seconds until your doors cycle thru lock-unlock. They will do this automatically while you are holding both remote keys. Now, Turn the key over again and then off. This should set your remote to work. If this does not work, there may be a problem with the remote or you may have a remote not compatible with vehicle or even dead battery in remote. Hope this saves someone some time and money!

There are some models that can be set up through the (DIC) Driver Information Center. You can go through the options in the DIC until you see where it says to (Learn New Remote) or something to that nature. When you push the check mark and hold it down it will say learning new remote. You then hold the unlock and lock buttons on your remote keyless entry. This may take a few seconds, but should take care of the programming process.

This really works! I just used it to program my 2005 Tahoe LT keyless entry system!
