Is your 2004 Cadillac DeVille key fob no longer working, or did you recently replace it? Reprogramming your key fob can often be done easily at home, saving you a trip to the dealership. This guide provides clear instructions on how to program your 2004 Cadillac DeVille key fob, ensuring you regain convenient keyless entry and remote functions.
There are two main procedures to program your key fob for your 2004 Cadillac DeVille, depending on whether your vehicle is equipped with the Driver Information Center (DIC). Don’t worry if you’re unsure; we’ll cover both methods to help you determine the right one for your car.
Method 1: Using the Driver Information Center (DIC)
This method is applicable if your 2004 Cadillac DeVille has the Driver Information Center. The DIC is typically controlled by buttons located on the steering wheel or instrument panel, often featuring a vehicle icon and the letter “i”.
-
Start the Ignition: Insert your key into the ignition of your 2004 Cadillac DeVille and turn it to the “ON” position. This is the position just before you would start the engine. Do not start the car.
-
Access Relearn Remote Key Menu: Use the vehicle information buttons on your DIC to scroll through the menu options. Continue pressing the button until you see the message “PRESS TO RELEARN REMOTE KEY” displayed on the DIC screen.
-
Initiate Programming Mode: Once “PRESS TO RELEARN REMOTE KEY” is displayed, press the set/reset button (often marked with a checkmark symbol) to confirm your selection. You should see “REMOTE KEY LEARNING ACTIVE” appear on the DIC screen. This indicates your 2004 Cadillac DeVille is now in programming mode and ready to learn the new key fob.
-
Program the First Key Fob: Take your first key fob that you want to program. Simultaneously press and hold both the “LOCK” and “UNLOCK” buttons on the fob for about 15 seconds. Listen carefully for an audible chime or acoustic signal from your vehicle. This sound confirms that the key fob has been successfully programmed.
-
Program Additional Key Fobs: If you have more key fobs to program, repeat step 4 immediately for each additional fob. It’s important to program all your key fobs, including any previously working ones, during this session, as the system typically clears the old codes when entering programming mode. Your 2004 Cadillac DeVille can store up to 8 key fobs.
-
Exit Programming Mode: After you have programmed all desired key fobs, turn the ignition switch to the “OFF” position and remove the key from the ignition.
-
Test Your Key Fobs: Test each programmed key fob to ensure it is working correctly. Check the lock, unlock, and any other functions your key fob may have, such as remote start or trunk release.
Method 2: Without Driver Information Center
If your 2004 Cadillac DeVille does not have the Driver Information Center, use this procedure to program your key fob.
-
Start the Ignition: Insert the key into the ignition of your 2004 Cadillac DeVille and turn it to the “ON” position. Again, this is just before starting the engine.
-
Access Relearn Remote Key: Locate the trip odometer reset button, usually found on the instrument cluster near the speedometer or tachometer. Press and release this button repeatedly until you see “RELEARN REMOTE KEY” appear in the display.
-
Initiate Programming Mode: Once “RELEARN REMOTE KEY” is displayed, press and hold the trip odometer reset button for approximately 3 seconds. The display should change to “REMOTE KEY LEARNING ACTIVE,” indicating that your 2004 Cadillac DeVille is now in key fob programming mode.
-
Program the First Key Fob: Take your first key fob and simultaneously press and hold the “LOCK” and “UNLOCK” buttons for about 15 seconds. Listen for the acoustic signal from your vehicle, confirming successful programming.
-
Program Additional Key Fobs: Repeat step 4 for any additional key fobs you need to program. Remember to program all fobs at once.
-
Exit Programming Mode: Turn the ignition to the “OFF” position and remove the key.
-
Test Your Key Fobs: Test all programmed key fobs to verify they are functioning as expected.
By following these steps, you should be able to successfully program your 2004 Cadillac DeVille key fob. If you encounter any difficulties or the programming is unsuccessful, it might be necessary to consult a professional locksmith or your local Cadillac dealership for assistance.
