- Insert Working Key: Insert your existing, correctly programmed key into the ignition.
- Turn Ignition to ON: Turn the ignition key to the “ON” position, but do not start the engine. Hold it in this position for about 10-15 seconds. You may hear a chime sound, and the security light on the dashboard might flash or turn off, indicating the vehicle has entered programming mode.
- Remove Working Key: Take out the working key from the ignition.
- Insert New Key Fob: Immediately insert the new, unprogrammed key fob into the ignition.
- Turn Ignition to ON Again: Turn the ignition to the “ON” position with the new key fob. Hold it for another 10-15 seconds. You should hear chimes again, indicating successful programming.
- Test New Key Fob: Turn the ignition OFF and remove the newly programmed key fob. Test all buttons (lock, unlock, remote start, panic, liftgate) to ensure they are functioning correctly.
If you have multiple key fobs to program, repeat steps 5-7 immediately after successfully programming the first new fob, using each new fob in turn.
This is what a typical key fob for a 2012 GMC Acadia Denali looks like, equipped with buttons for lock, unlock, remote start, panic alarm and liftgate release.
