How do you program your hhr key fob?

Answer 1

To program your HHR key fob, first, insert the key into the ignition and turn it to the "On" position without starting the engine. Press and hold the "Unlock" button on the fob while also pressing the "Lock" button three times, then release the "Unlock" button. Turn the ignition off and test the fob to ensure it works. If necessary, repeat the process for any additional fobs.
