2004 Cadillac XLRFACTORY OEM SERVICE PROCEDURE

Method 2 - Key Fob Slot Programming

This procedure will add or replace a key fob. Method 2 allows you to choose which location (slot) the unprogrammed fob will be learned to. If you are replacing a key fob, this method will erase the previously known key fob programmed to that particular slot. This procedure requires that you have a known good key fob, a replacement key fob, the vehicles mechanical key, and a scan tool.

IMPORTANT: This procedure is not available when the maximum number of Fob's (4) have been programmed. If 4 key fobs are programmed to this RCDLR and this method is attempted, the 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. Open the rear compartment.
  3. Place a known key fob within the interior of the vehicle.
  4. Install a scan tool.
  5. Use the scan tool, to access the following:
    • Vehicle Control Systems
    • Computer/Integrating Systems
    • Module Replacement/Setup
    • RCDLR
    • Program Key Fobs
  6. At the rear of the vehicle insert the vehicle key in the rear compartment lock cylinder located in the lower left and cycle the key 5 times within 5 seconds.
  7. Select Fob X (X = 1, 2, 3, or 4) on the scan tool. This will be the slot you wish to program to.
  8. Place the replacement key fob in the glove box pocket with the buttons facing right. A beep will occur indicating programming completion. The previously known fob is now erased.
  9. If programming additional key fobs, repeat steps 4-8, or press the OFF/ACC portion of the ignition switch to exit programming.
  10. Remove the scan tool.
    IMPORTANT: Failure to operate the active portion of each key fob will result in that fob being inoperative. Pressing the active portion finishes the programming sequence and is require to ensure transmitter operation.
  11. Operate the active portion of each key fob in order to verify correct system operation.
