Step-by-Step Guide to Cadillac XT4 Key Fob Battery Replacement
Replacing the battery in your Cadillac XT4 key fob is a simple task that requires minimal tools and time. Follow these step-by-step instructions to get your key fob working like new again.
Tools You’ll Need
Before you begin, gather the necessary tools. Luckily, you likely already have everything you need right at home:
- New CR2032 Battery: Ensure it’s a fresh, unused battery for optimal performance.
- Small Flathead Screwdriver or Key Fob Tool: This will be used to gently pry open the key fob casing. A small, plastic trim removal tool can also work to prevent scratches.
- Soft Cloth (Optional): To protect the key fob surface from scratches during the opening process.
Having these tools ready will ensure a smooth and efficient battery replacement.
Opening the Key Fob
The first step is to carefully open your Cadillac XT4 key fob to access the battery compartment.
- Locate the Release Latch: On the back of your key fob, you’ll find a small release latch or button.
- Release the Emergency Key: Press and hold the release latch while simultaneously pulling out the mechanical emergency key. Set the key aside; you won’t need it for the battery replacement but keep it in a safe place.
- Find the Opening Slot: Once the emergency key is removed, you’ll see a small slot or seam where the two halves of the key fob casing meet.
- Pry Open the Casing: Insert the tip of your flathead screwdriver or key fob tool into the slot. Gently twist or pry to separate the two halves of the key fob casing. Work your way around the seam if necessary, applying gentle pressure until the case pops open. Be careful not to apply excessive force to avoid damaging the casing.

Removing the Old Battery
With the key fob casing open, you can now access and remove the old battery.
- Locate the Battery: The CR2032 battery will be visible inside one half of the key fob casing. It’s usually held in place by small clips or a retaining bracket.
- Note Battery Orientation: Pay close attention to the orientation of the battery. Typically, the positive (+) side faces upwards. Noting this will ensure you install the new battery correctly.
- Remove the Old Battery: Use your fingertip or the edge of the flathead screwdriver to gently pry the old battery out of its compartment. Avoid using excessive force that could damage the battery contacts.
Inserting the New Battery
Now it’s time to install the new CR2032 battery into your Cadillac XT4 key fob.
- Position the New Battery: Place the new CR2032 battery into the battery compartment, ensuring the positive (+) side is facing the same direction as the old battery was removed (usually upwards).
- Press Battery into Place: Gently press down on the new battery until it clicks securely into place under the retaining clips or bracket. Ensure it is firmly seated to make good contact.
Closing the Key Fob
With the new battery installed, carefully reassemble the key fob casing.
- Align the Casing Halves: Line up the two halves of the key fob casing.
- Press Casing Together: Press the two halves firmly together until they snap back into place. You should hear a click, indicating that the casing is securely closed. Ensure there are no gaps along the seam.
- Reinsert Emergency Key: Slide the mechanical emergency key back into its slot until it clicks into place.
Testing Your Key Fob
The final step is to test your Cadillac XT4 key fob to ensure the battery replacement was successful.
- Test Lock/Unlock Buttons: Press the lock and unlock buttons on your key fob. Verify that your Cadillac XT4 responds by locking and unlocking the doors.
- Test Remote Start (if applicable): If your Cadillac XT4 is equipped with remote start, test this feature to ensure it is functioning correctly.
- Start Your Vehicle: Get into your Cadillac XT4 and start the engine using the push-button start. Ensure the vehicle detects the key fob and starts without issue.
If all functions are working correctly, you have successfully replaced your Cadillac XT4 key fob battery. If you encounter any issues, double-check that the battery is installed correctly and is the correct type. If problems persist, you may need to consult your Cadillac dealer.
