Programming Your 2007 Cadillac STS Key Fob
Before you begin, ensure you have all the key fobs you intend to use with your vehicle, as you will need to program them all in one session.
Here are the programming steps for your 2007 Cadillac STS key fob:
-
Start in the Off Position: Make sure your Cadillac STS is turned off and the key is removed from the ignition.
-
Prepare the Remotes: Have both your new, unprogrammed remote and at least one existing, working remote inside the vehicle’s cabin with you.
-
Door Lock Cycling: Insert your key into the driver’s side door lock cylinder. Cycle the lock cylinder to the UNLOCK position five times in rapid succession (within 5 seconds).

DIC Display: After successfully cycling the door lock, the Driver Information Center (DIC) will display “READY FOR FOB #X” (where X indicates the remote number being programmed, starting with 2, then 3, and so on).
-
Locate the Remote Pocket: Open the center console between the driver and passenger seats. You’ll find a designated remote pocket inside.

Program the New Fob: Place the new, unprogrammed remote into the center console pocket, ensuring the buttons are facing forward.
-
Programming Confirmation: You will hear an audible tone confirming successful programming. The DIC will then display “READY FOR FOB #X” or “MAX # FOBS LEARNED,” indicating the programming status.
-
Program Additional Remotes: If you have more remotes to program, remove the first programmed remote and place the next remote into the pocket. Repeat steps 6 and 7 for each additional key fob.
-
Exit Programming Mode: Once you have programmed all desired key fobs, you can exit the programming mode. Simply turn off the vehicle and remove the key.
-
Test Your Remotes: Test all programmed remotes to ensure they are functioning correctly with your 2007 Cadillac STS.
Important Note for Remote Start Fobs: If you are programming key fobs with a remote start function, after programming, you MUST idle your Cadillac STS for 20 to 30 minutes with the remotes remaining in the programming pocket within the center console. This step is crucial for the remote start feature to function properly.
By following these instructions, you can easily program your 2007 Cadillac STS key fob and regain full access to your vehicle’s keyless entry and remote functions. If you encounter any issues or prefer professional assistance, consider searching for a local key fob programming service in your area.
