3. Step-by-Step Programming Procedures

There are two main procedures to program your 2009 Cadillac CTS key fob, depending on whether your vehicle has a Driver Information Center (DIC) or not. Follow the appropriate procedure carefully.

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

This procedure is for vehicles equipped with a Driver Information Center, which typically has a button to the right of the steering wheel labeled with a vehicle icon and the letter “i”.

Insert Key and Turn Ignition ON: Insert your key into the ignition and turn it to the “ON” position, just before starting the engine.
Access the Relearn Menu: Press the vehicle information button until “PRESS TO RELEARN REMOTE KEY” is displayed on the DIC.
Initiate Programming Mode: Press the set/reset button (usually marked with a checkmark) until “REMOTE KEY LEARNING ACTIVE” is displayed. The vehicle is now in programming mode.
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.
Program Additional Remotes: Repeat step 4 for any additional remotes you want to program. You can program up to 8 remotes for this vehicle. Ensure you program ALL remotes, including existing ones.
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 vehicles without a Driver Information Center.

Insert Key and Turn Ignition ON: Insert the key into the ignition and turn it to the “ON” position (just shy of starting the engine).
Access the Relearn Menu: Press the trip odometer reset button until “RELEARN REMOTE KEY” is displayed.
Initiate Programming Mode: Press and hold the trip odometer reset button for approximately 3 seconds until “REMOTE KEY LEARNING ACTIVE” is displayed.
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 will indicate successful programming.
Program Additional Remotes: Repeat step 4 to program any additional remotes. You can program up to 8 remotes for this vehicle. Make sure to program ALL remotes, including any existing ones.
Exit Programming Mode: Turn the ignition OFF, remove the key, and test all remotes.

Sometimes, programming doesn’t go as planned. Here are some common issues and how to address them:

Key Fob Not Responding:
- Ensure the battery is new and correctly installed.
- Double-check the programming steps.

Vehicle Not Entering Programming Mode:

4. Advanced Programming Techniques

For those who want to delve deeper, here are some advanced techniques and tips to enhance your key fob programming experience.

A diagnostic tool can simplify the programming process, especially for newer vehicles. These tools often provide step-by-step instructions and can diagnose any underlying issues.

Connect the Diagnostic Tool: Plug the tool into the OBD-II port under the dashboard.
Follow On-Screen Instructions: Navigate to the key fob programming section and follow the prompts.
Program the Key Fob: The tool will guide you through the programming steps, often automating much of the process.

4.2. Programming with Multiple Key Fobs

When programming multiple key fobs, ensure you program all of them in the same session. The vehicle typically clears the memory of old key fobs when new ones are programmed.

Gather All Key Fobs: Have all key fobs you want to use ready before starting.
Follow the Programming Procedure: Program each key fob one after the other, following the steps outlined above.
Test All Key Fobs: After programming, test each key fob to ensure they all work correctly.

In some cases, you may need to reset the vehicle’s security system to clear any errors or conflicts.

Disconnect the Battery: Disconnect the negative terminal of the car battery for a few minutes.
Reconnect the Battery: Reconnect the negative terminal.
Try Programming Again: Attempt the key fob programming procedure again.
