Locate the opening notch on the side edge of the key. Use a screwdriver to pry open along the side seam. The battery is located beneath this back cover. Apply slight upward force to partially lift the back cover, then press the battery at the clip area to make it protrude. Replace the battery accordingly.

As an ordinary car owner, I recently replaced the battery in my Buick Excelle key because the remote wasn't working well. The key is a folding type, and it uses a small coin cell battery CR2032, which can be bought at any supermarket. The replacement process is super simple, just a few steps: first open the key, look for a small groove on the side or bottom, gently pry it open with a coin or small flat-head screwdriver, but don't use too much force to avoid damaging the plastic case. After opening the case, you'll see a round battery inside, just pop it out. Note that the battery has a positive and negative side, make sure to install the new battery in the same orientation as the old one, usually with the positive side facing up. Then close the case and press firmly until you hear a click. After replacement, it worked normally, and the whole process took just a few minutes. Just be careful not to cut your fingers and keep the tools clean. If the key is a smart card type, the steps are similar but might require a bit more skill. Regularly replacing the battery can save a lot on repair costs, generally every two years is fine.

I'm used to this job, changing the battery for an old model like the Buick Excelle is pretty straightforward. First, prepare some tools, like a small Phillips screwdriver or a thin plastic piece, depending on the key design. Many Excelle models have a thin slit on the back—just slot the tool in and gently pry it open. The battery inside is a CR2032; after removing it, simply replace it with a new one, but avoid touching the metal surface to prevent static interference. When putting it back, make sure the cover is aligned and pressed firmly. I’ve done this several times myself—just pay attention to safety details, like keeping the area free of water or grease. I recommend buying branded batteries for stable quality; avoid the cheapest ones. The whole process takes about five minutes—simple and hassle-free, saving you the cost of hiring a technician. If the key has an anti-theft chip, handle it more carefully, gently placing it back without touching the chip. The battery usually needs checking every year and a half.

I'm a new driver. Last time my Buick Excelle key fob stopped working, a friend taught me how to replace the battery. It's very simple: There's usually a seam on the key fob. Use a stiff card or key blade to pry it open, then you'll see a small battery inside. Remove it and replace it with a new one. Make sure not to put it in backwards—the positive side should face up. Then snap the cover back on firmly. The whole process takes less than two minutes, is inexpensive and convenient. If you can't open it, check the manual or look up a tutorial online.
