Lost your key fob or need to program a new one for your 2008 Cadillac CTS? Don’t worry, you might be able to do it yourself! This guide provides straightforward instructions for programming your 2008 Cadillac CTS key fob, saving you time and potentially money. Whether your CTS has the Driver Information Center (DIC) or not, we’ve got you covered with easy-to-follow procedures.
Procedure #1: For 2008 Cadillac CTS with Driver Information Center
If your 2008 Cadillac CTS is equipped with the Driver Information Center, programming your key fob is a relatively simple process. The Driver Information Center is typically located to the right of your steering wheel and features buttons with a vehicle icon and the letter “i”. Here’s how to program your key fob using this system:
-
Ignition Ready: Insert your key into the ignition. Turn the ignition switch to the “ON” position. This means turning the key just before you would start the engine – you should see the dashboard lights illuminate, but the engine should not be running.
-
Access Relearn Mode: Locate the vehicle information button on your Driver Information Center (the button with the vehicle icon and “i”). Press this button repeatedly until you see the message “PRESS TO RELEARN REMOTE KEY” displayed on the DIC screen.
-
Initiate Learning: Once “PRESS TO RELEARN REMOTE KEY” is displayed, press the set/reset button (this button usually has a checkmark symbol). Press it until the DIC screen shows “REMOTE KEY LEARNING ACTIVE”. At this point, your 2008 Cadillac CTS is in programming mode, ready to learn the new key fob.
-
Program First Remote: Take your first key fob remote. Simultaneously press and hold both the “LOCK” and “UNLOCK” buttons. Keep holding them for approximately 15 seconds. After about 15 seconds, you should hear an audible chime or acoustic signal from your vehicle. This sound indicates that the key fob has been successfully programmed.
-
Program Additional Remotes: If you have additional key fobs to program (including any existing remotes you want to continue using), repeat step 4 for each one. It’s important to program all remotes you intend to use during this session, as the system can handle up to 8 remotes.
-
Exit Programming Mode: To finish the programming process, simply turn the ignition switch to the “OFF” position and remove the key from the ignition.
-
Test Your Remotes: Thoroughly test all programmed key fobs to ensure they are working correctly. Try locking and unlocking the doors, activating the trunk release, and using the panic button to confirm full functionality.
Procedure #2: For 2008 Cadillac CTS without Driver Information Center
If your 2008 Cadillac CTS model does not have the Driver Information Center, you can still program your key fob using a slightly different procedure that utilizes the trip odometer reset button. Here’s how to do it:
-
Ignition On: Insert the key into the ignition and turn it to the “ON” position, just before starting the engine. Make sure the engine is not running, but the electrical systems are active.
-
Enter Relearn Mode: Locate the trip odometer reset button, usually found on the instrument panel near the speedometer and tachometer. Press and release this button repeatedly until the display shows “RELEARN REMOTE KEY”.
-
Activate Learning: Once “RELEARN REMOTE KEY” is displayed, press and hold the trip odometer reset button for approximately 3 seconds. Continue holding until the display changes to “REMOTE KEY LEARNING ACTIVE”. Your vehicle is now ready to program key fobs.
-
Program First Key Fob: Take your first key fob. Press and hold the “LOCK” and “UNLOCK” buttons simultaneously for about 15 seconds. Listen for the acoustic signal (chime) which will confirm successful programming of the remote.
-
Program Remaining Remotes: If you have more key fobs to program, repeat step 4 for each additional remote. Remember to program all desired remotes, as the system programs all remotes present during the session.
-
Exit Programming: Turn the ignition switch to the “OFF” position and remove the key from the ignition to exit the key fob programming mode.
-
Verify Functionality: Test each programmed key fob to ensure it properly locks and unlocks the doors, releases the trunk, and activates the panic alarm.
