How do you program a keyless remote for a 2005 Chevy Trailblazer?

Answer 1

Make sure all doors are closed, to include the hatch. put key in the ignition but do not turn yet. On the drivers side door, press and hold the unluck button on the door and keep held until told to release. Next turn the key on til just ebfore turning the cars engine over. then torun back to off then on then off. Now release the unlock button, This should turn your cars FOB into reset mode and you wll know this occurs if your doors lock and then unlock, might do this twice. Next press and hold the lock/unlock button on the FOB until the doors again lock and unlock again, might take 30 or so seconds. Turning the key to the on position again will complete this process.
