Are you looking to program a new key fob for your 2008 Cadillac STS? Whether you’ve lost your old one or simply want a spare, programming a new key fob yourself can save you time and money compared to dealership services. This guide provides clear, easy-to-follow instructions for programming your 2008 Cadillac STS key fob right at home.
Before you begin, ensure you have all the key fobs you intend to use with your vehicle, as you’ll need to program them all at once during this process. Let’s get started with programming your 2008 Cadillac STS key fob.
Programming Steps:
-
Vehicle Preparation: Begin by turning off your 2008 Cadillac STS completely and removing the key from the ignition.
-
Prepare Remotes: Gather your currently working key fob and the new key fob you wish to program. Have both remotes with you inside the vehicle’s cabin.
-
Door Lock Cycling: This step initiates the programming sequence. Insert your key into the driver’s side door lock cylinder. Within 5 seconds, cycle the lock cylinder to the UNLOCK position five times. It’s crucial to perform these cycles quickly and within the time limit for the system to recognize the programming request.
-
DIC Display: After successfully cycling the door lock, the Driver Information Center (DIC) display in your Cadillac STS will show a message. This message will indicate that the system is “READY FOR FOB #X,” where X represents the next remote to be programmed (e.g., 2, 3, or 4). This confirms that your vehicle has entered programming mode and is ready to learn new key fobs.
-
Locate Remote Pocket: Inside your 2008 Cadillac STS, find the designated remote pocket. This pocket is located in the center console, positioned between the driver and passenger seats.
-
Place New Remote: Take the new, unprogrammed key fob and place it into the remote pocket in the center console. Ensure that the button side of the remote is facing forward as you place it in the pocket.
-
Programming Confirmation: Once the key fob is successfully programmed, you will hear an audible tone from your Cadillac STS. The DIC display will also update to show either “READY FOR FOB #X” if you can program more remotes, or “MAX # FOBS LEARNED” if the maximum number of remotes has been programmed.
-
Program Additional Remotes (If Necessary): If you have more key fobs to program, remove the first programmed remote from the pocket and place the next key fob you want to program into the remote pocket. Repeat step 7 for each additional remote.
-
Exit Programming Mode and Test: After you have programmed all desired key fobs, you can exit the programming mode. Simply remove the key from the door lock cylinder or turn on the ignition. Test all programmed key fobs to ensure they are working correctly by locking and unlocking the doors and, if applicable, testing the remote start function.
Important Note for Remote Start Function: If you are programming key fobs that are equipped with a remote start function, there is an additional step required. After programming the remotes as described above, you must idle your 2008 Cadillac STS for 20 to 30 minutes with the newly programmed remotes still placed in the programming pocket. This step is necessary to synchronize the remote start feature with the vehicle’s system.
