Method to replace the battery in a Buick GL8 remote key: 1. Remove the mechanical key and use a screwdriver or other tool to open the key cover; 2. Once the key cover is opened, you will see the battery. Remove the old battery and replace it with a new one; 3. When installing the new battery, ensure the positive side faces upward, then close the key cover. The Buick GL8 is an MPV model under the Buick brand, with dimensions of 5256mm in length, 1878mm in width, and 1776mm in height, and a wheelbase of 3088mm. In terms of suspension, the Buick GL8 uses a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear.
I've replaced the battery in my Buick GL8 remote key several times myself—it's not difficult. First, remember to confirm the key type. For older straight keys, look for a small groove in the middle of the side with the remote buttons. For newer folding keys, the mechanical key slot is often hidden behind the Buick emblem. Use your fingernail to pry open a small gap, then insert a coin or a small flathead screwdriver to gently lift it open. Be careful not to pry too hard, as the case clips are fragile. Once the case is open, you'll see the battery, usually a CR2032 coin cell. To remove the old battery, simply use your fingernail to lift it from the edge. When installing the new battery, make sure the positive side faces upward—the printed side should be visible. Test the key buttons to see if the red light turns on. If it does, snap the case back together. A special reminder: check if the waterproof rubber ring has shifted—it's essential for preventing rain damage. I also recommend using an eraser to clean the yellow metal contacts on the circuit board for better responsiveness.
You'll need a CR2032 battery, which can be purchased at supermarkets for around 5 yuan—just make sure not to get the wrong model. I usually keep thin plastic sheets or eyebrow tweezers handy, as metal tools can easily scratch the key. When opening the case, locate the hidden clip first; carefully feel along the edge of the remote for a slight protrusion—that's where the plastic pry tool should be inserted. Be extra cautious when separating the shell to avoid tearing the ribbon cable, as some models have the circuit board attached to the upper cover. After replacement, test the response speed of the lock/unlock buttons—if they're slower, it's likely due to poor battery contact or incorrect installation. The whole process takes no more than ten minutes DIY, whereas a dealership visit could cost you 80 yuan in labor fees alone, not to mention the wait time.
