Buick Key Fob Battery: When It’s Time

How do you know when you need a Buick key fob battery replacement? Generally, you’ll observe that the range of effectiveness reduces rapidly, and your Buick key fob just is not as effective at unlocking your doors from a distance.

How to Open a Buick Key Fob

Not sure how to change the battery in a Buick key fob? Learning how to open a Buick key fob is easy—just like removing batteries from a child’s toy or a TV remote. Simply follow these instructions on how to change a battery in a Buick key fob:

1. Press the button at the top of the key fob to release the internal key. Usually, a key fob has a regular key embedded inside, so that the car can still work with a conventional key.
2. Once the key is removed, you will notice a slot in the middle of the space. Use a flathead screwdriver to pry open the key fob between the two small dents where the physical key used to be. Then, remove the Buick key fob battery cover.
3. After you’ve removed the battery cover, you will be able to see the battery. Remove the silver disc with the screwdriver, or remove it by hand. Confirm that the new Buick key fob replacement is the right size.
4. Install the new battery by pushing it into the gap with the positive side facing downward. With the battery locked into place, reattach the cover and click the two sides together, as you should hear them snap into place. Then you should be ready to go.
