I drove a Buick GL8 for many years and know the frustration of a remote control running out of battery. Replacing the battery is actually quite simple. First, prepare a small screwdriver or coin and use it to gently pry open the shell at the gap of the key—be careful not to use too much force to avoid scratching the plastic. Once opened, you’ll see a small button battery, model CR2032, which can be bought for a few dollars at a supermarket or auto parts store. Carefully remove the old battery with a tool, making sure not to lose the spring clip. Then, insert the new battery with the positive side (marked side) facing up, close the shell, and press firmly to secure it. After replacement, test the door unlocking and locking functions immediately. If there’s no response, it might be due to poor contact—double-check the installation. Pay attention to signs of weakening key signals, such as shorter range or slower response, as these indicate it’s time to replace the battery. Don’t wait until it’s completely dead and causes trouble. Keep a spare battery in the car for emergencies—a simple DIY fix saves you a hundred bucks at the dealership.
