3. Step-by-Step Programming Instructions for Cadillac CTS

Programming your Cadillac CTS key fob can be done in a few simple steps. Here are two procedures, one for vehicles with the Driver Information Center (DIC) and one for those without.

3.1. Procedure #1: Vehicles with Driver Information Center (DIC)

This procedure applies to Cadillac CTS models equipped with a Driver Information Center, typically a button to the right of the steering wheel with a vehicle icon and the letter “i”.

3.1.1. Step 1: Ignition On

Insert the key into the ignition and turn it to the “ON” position. This is just shy of starting the vehicle, without cranking the engine.

3.1.2. Step 2: Access Relearn Mode

Press the vehicle information button until “PRESS TO RELEARN REMOTE KEY” is displayed on the DIC screen.

3.1.3. Step 3: Enter Programming Mode

Press the set/reset button (usually a button with a checkmark) until “REMOTE KEY LEARNING ACTIVE” is displayed. The vehicle is now in programming mode.

3.1.4. Step 4: Program the First Remote

Press and hold both the LOCK and UNLOCK buttons simultaneously on the first remote for approximately 15 seconds. You should hear an acoustic signal indicating successful programming.

3.1.5. Step 5: Program Additional Remotes

Repeat step 4 for each additional remote you want to program. You can program up to 8 remotes for your Cadillac CTS. Remember to program ALL remotes, including any existing ones.

3.1.6. Step 6: Exit Programming Mode

Turn the ignition OFF, remove the key, and test all remotes to ensure they are working correctly.

3.2. Procedure #2: Vehicles without Driver Information Center (DIC)

This procedure is for Cadillac CTS models that do not have a Driver Information Center.

3.2.1. Step 1: Ignition On

Insert the key into the ignition and turn it to the “ON” position, just before starting the engine.

3.2.2. Step 2: Access Relearn Remote Key

Press the trip odometer reset button until “RELEARN REMOTE KEY” is displayed.

3.2.3. Step 3: Activate Learning Mode

Press and hold the trip odometer reset button for approximately 3 seconds until “REMOTE KEY LEARNING ACTIVE” is displayed.

3.2.4. Step 4: Program the First Remote

Press and hold the LOCK and UNLOCK buttons at the same time on the first remote for about 15 seconds. An acoustic signal should indicate successful programming.

3.2.5. Step 5: Program Additional Remotes

Repeat step 4 to program any additional remotes. You can program up to 8 remotes, and you must program all remotes, including existing ones.

3.2.6. Step 6: Exit Programming Mode

Turn the ignition OFF, remove the key, and test all remotes to ensure proper function.

4. Troubleshooting Common Programming Issues

Even with careful execution, you may encounter issues during the programming process. Here are some common problems and how to troubleshoot them.

4.1. Key Fob Not Responding
