Method 1 - Key Fob Quick Learn

This procedure will add key fobs. Fobs will be numbered in sequence based on when they are programmed; if 2 fobs are currently programmed to the RCDLR, a fob programmed using this method will be numbered as Fob 3. This procedure requires that you have a known good key fob, a replacement key fob, and the vehicles mechanical key.

IMPORTANT: This procedure is not available when the maximum number of fobs (4) have been programmed. If 4 key fobs are programmed to this RCDLR and this method is attempted, the driver information center (DIC) will display MAX FOBS LEARNED and the programming procedure will exit. Method 4 must be used in this instance.
  1. The vehicle must be OFF.
  2. Place a known key fob within the interior of the vehicle.
  3. Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds.
  4. The DIC will display a message: READY FOR FOB X (X = fob 2, 3, or 4).
  5. Place the replacement key fob in the console fob pocket with the buttons facing forward.
  6. A beep will occur and the DIC will display: READY FOR FOB X (X = fob 3 or 4) or MAX FOBS LEARNED.
  7. If programming additional key fobs, repeat steps 5 and 6, or press the OFF/ACC portion of the ignition switch to exit programming mode.
  8. Operate the active portion of each key fob in order to verify correct system operation.
