How to disassemble and assemble a Buick car key?

Buick car key disassembly and assembly method: Use a small screwdriver to remove the fixing screws, then use a small tool to pry off the upper cover along the gap; when installing the car key, reverse the operation. It should be noted that the spring must be rotated counterclockwise once before it can be snapped on, otherwise the mechanical key will not pop out. The function keys of the Buick car key include: unlock button, lock button, trunk opening button, RES remote start button, and car finder button. Buick is a car brand under General Motors of the United States, established in 1904, mainly producing mid-to-high-end cars, including new energy vehicles, sedans, SUVs, and MPVs.
The last time I took apart my Buick key, the whole process was actually quite straightforward. First, locate the edge of the key where there's a small gap or a tiny button, as designs may vary slightly between different models. I recommend having a thin plastic tool or a small screwdriver ready to gently pry open the casing—avoid using metal tools to prevent scratches. Once opened, you'll see the circuit board inside and a small button battery, typically a CR2032 model. Take note of the positive and negative terminal orientation. After replacing the battery, align the casing and press it gently until you hear a click, indicating it's properly secured. If you notice the battery drains quickly, it might be an issue with the internal chip, so it's a good idea to check the connections while you're at it. I once installed the battery backward, which caused the key to stop working, and I had to visit the dealership for a replacement—so it pays to be careful. The whole process takes about 5 minutes, but patience is key.
