This method applies to vehicles equipped with a Driver Information Center (DIC).

1. Insert Key and Turn to ON Position:
   Insert the ignition key into the ignition switch and turn it to the “ON” position. This is the position just before starting the engine.

4. Program the First Key Fob:
   Simultaneously press and hold the LOCK and UNLOCK buttons on the first remote key for approximately 15 seconds. Listen for an acoustic signal, such as a chime or beep, which indicates successful programming. According to a GM service bulletin, the acoustic signal confirms that the vehicle has recognized the key fob’s signal.

5. Program Additional Key Fobs:
   Repeat step 4 for each additional key fob you want to program. You can program up to eight key fobs for your 2005 Cadillac DeVille. Make sure to program all existing remotes, as the system will only recognize the remotes programmed during this session.

4. Program the First Key Fob:
   Press and hold the LOCK and UNLOCK buttons on the first remote key simultaneously for about 15 seconds. Listen for an acoustic signal confirming successful programming.

5. Program Additional Key Fobs:
   Repeat step 4 for each additional key fob you want to program. You can program up to eight key fobs. Ensure all existing remotes are programmed during this session.
