How to Change the Battery in a Buick Key Fob

Changing the battery in your Buick key fob is a simple process, but if done incorrectly, it can result in damage. Here’s how to change the battery in a Buick key fob: 

1. How to Open a Buick Key Fob: Using a flathead screwdriver, gently pry the key fob’s two halves apart. Ensure you do this with care to avoid any damage to the outer casing.
2. How to Take Apart a Buick Key Fob:Once opened, you’ll notice the Buick Key Fob battery housed within. Before removing it, note the battery’s position to ensure you place the new battery correctly.
3. Replace the old battery with a new one. Typically, a CR2032 battery is used for Buick key fobs.
4. Reassemble the key fob by pressing the two halves together until you hear a click, indicating they’re securely in place.

Buick Key Fob Battery Quality Matters

Using the right Buick key fob battery is essential. We recommend high-quality batteries to ensure your key fob performs optimally and lasts longer. Cheap batteries can run out quickly and may even damage your key fob in the long run.

How to Program a Buick Key Fob

After replacing the battery, you may wonder how to program a Buick key fob. While many key fobs will work immediately after a battery replacement, others may need reprogramming. 

1. Insert the key into the ignition, but don’t turn it just yet. 
2. Use the manual lock on your driver’s door to lock all the doors.
3. Turn the key to the “On” position (without starting the car) and right back to the “Off” position quickly.
4. Do the turn to the “On” and “Off” position steps a total of three times.
5. If done correctly, the door locks should cycle (lock and unlock on their own), indicating the vehicle is now in programming mode.
6. On the key fob, press and hold both the “Lock” and “Unlock” buttons simultaneously for about 15 seconds. If the programming is successful, the door locks will cycle again.
7. Remove the key to exit programming mode.
8. Ensure that the buttons on the key fob operate correctly.
