How to Program a Chevy Tahoe Remoteby Leonardo R. Grabkowski
The Chevrolet Tahoe comes standard with remote keyless entry, as do many modern vehicles. If your remote is lost or damaged and you want to replace it, you'll need to program its replacement before it can be used. You can also program additional remotes, beyond the two that come with your Tahoe (the Tahoe's memory will store up to eight). The process is different between the third-generation (2007 to 2010) and the second-generation Tahoe (1999 to 2006).
Third-Generation Tahoe (2007 to 2010)
Shift your Tahoe into park and move the key into the "On" position.
Hold the trip odometer button (right side of instrument cluster) for three seconds, until the message "Remote Key Learning Active" is displayed.
Press and hold the "Lock" and "Unlock" buttons on the remote for fifteen to twenty seconds, until you hear a confirmation chime.
Turn the ignition to "Off" and remove the key to finalize the programming sequence.
Second-Generation Tahoe (1999 to 2006)
Make sure all the doors are closed, and then insert the key without turning it.
Press and hold the "Unlock" button on the door panel (hold it while performing step three).
Turn the ignition to "On" (without cranking), and then back to "Off". Then, turn it to "On" and back to "Off" again.
Release the "Unlock" button on the door panel.
Press and hold the "Unlock" and "Lock" buttons on your remote until the door locks cycle (this will take approximately 30 seconds).
