Are you looking to program a new key fob for your 2009 Cadillac STS? Perhaps you’ve purchased a replacement key fob or need to program an additional remote. Fortunately, programming a key fob for your 2009 Cadillac STS can be done relatively easily at home without needing to visit a dealership. This guide provides you with straightforward, step-by-step instructions to program your 2009 Cadillac STS key fob.
Before you begin, make sure you have all the key fobs you intend to program with you, as you will need to program all of them in one session. Here’s how to program your 2009 Cadillac STS key fob:
Programming Instructions:
-
Start with the Vehicle Off: Ensure your Cadillac STS is completely turned off and the key is removed from the ignition.
-
Gather Your Remotes: Bring all remote transmitters, both currently functioning ones and any new ones you wish to program, inside the vehicle cabin with you.
-
Door Lock Cylinder Cycling: Insert your key into the driver’s side door lock cylinder. Within 5 seconds, cycle the lock cylinder to the UNLOCK position 5 times.
-
DIC Display Confirmation: After cycling the lock cylinder, observe the Driver Information Center (DIC) display. It should show “READY FOR FOB #X” (where X indicates the remote number being programmed, starting from 2, then 3, and so on).
-
Locate the Remote Pocket: Find the remote pocket located in the center console between the driver and passenger seats.
-
Place Remote in Pocket: Take the new, unprogrammed remote and place it into the designated pocket in the center console. Ensure the buttons on the remote are facing forward.
-
Programming Completion: Once the programming process is successfully completed for that remote, you will hear an audible tone. The DIC will then display either “READY FOR FOB #X” if you have more remotes to program, or “MAX # FOBS LEARNED” if you have programmed all remotes.
-
Repeat for Additional Remotes (If Necessary): If you have more remotes to program, remove the remote that was just programmed from the pocket and place the next remote to be programmed into the remote pocket. Repeat steps 7 for each additional remote.
-
Exit Programming Mode and Test: After you have programmed all desired key fobs, you can exit the programming mode. Test each remote to ensure it is properly programmed and functioning correctly with your 2009 Cadillac STS.
Important Note for Remote Start Function: If you are programming key fobs that include a remote start function, it is crucial to idle your vehicle for 20 to 30 minutes after programming and leave the remotes in the programming pocket during this idling period. This step is necessary to ensure the remote start function is properly synchronized.
If you encounter any difficulties programming your key fob or prefer professional assistance, you can search for a qualified key fob installer in your local area. Programming your 2009 Cadillac STS key fob yourself can save you time and money, getting you back on the road quickly with a fully functional remote.
