Key Fob Auto Learn
This procedure will first erase all known key fobs. The procedure will then program a single or multiple key fobs. Method 3 is a series of three 10-minute key cycles, for a total of 30 minutes. This procedure requires that you have a replacement key fob and the vehicle mechanical key.

Important: All previously programmed key fobs will be erased upon completion of the 30-minute programming procedure. The order in which the key fobs are programmed will determine its numbering position within the RCDLR memory. The first key fob programmed will be key fob #1, and the second key fob programmed will be key fob #2. The number stamped on the key fob case is for reference only: #2 can be programmed as #1.
Do not place any known good key fobs in the vicinity of the vehicle when programming. 

The vehicle must be OFF. 
Place the replacement key fob in the console pocket with the buttons facing forward. 
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. 

The DIC will display a message: OFF/ACC TO LEARN. 
Press the OFF/ACC portion of the ignition button. 
The DIC will display a message: WAIT 10 MINUTES, then it will count down from 10 to 0, one minute at a time. 
When the counter reaches 0, DIC will display OFF/ACC TO LEARN. 
Repeat steps 5-7 two more times, for a total of 30 minutes. 
The DIC will display a message: OFF/ACC TO LEARN. 
Press the OFF/ACC portion of the ignition button. 
A beep will occur and the DIC will display: READY FOR FOB 1. At this time all previously known key fobs have been erased. When fob 1 is programmed a beep will be heard and the DIC will display a message: READY FOR FOB 2. 
Additional key fobs can be programmed by taking fob 1 out of the pocket and inserting fob 2. If desired, up to 4 fobs can be programmed. Once 4 fobs have been learned, the DIC will display a message: MAX FOBS LEARNED, and automatically exit the program mode. 
If learning less than 4 key fobs, press the OFF/ACC portion of the ignition button to exit the program mode. 
Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation. 

Good luck and hope this help's keep me posted, there are 3 other methods and the 5th method is a tech 2 scan tool that the dealer uses but this should work on your year of cadillac.

Transmitter ProgrammingImportant: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

1. Install a scan tool.
2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
3. Press the START soft key on the scan tool. Important: The scan tool must stay connected until all of the transmitters are programmed.
   
4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.
