There is a gap on the side of the Excelle car key. Use your fingernail to pry open the gap on the side of the Buick Excelle car key shell. Locate the battery inside the Buick Excelle car key and remove it. Install the new battery, making sure the battery is inserted in the correct orientation. Finally, close the shell of the Buick Excelle car key. This completes the battery replacement for the Buick Excelle car key.

With over a decade of car repair experience, changing the battery for an Excelle key is a piece of cake for me. Just grab a small Phillips screwdriver—see that tiny groove on the back of the key? Pry open the back cover, and the battery will be exposed. The old battery is a CR2032 coin cell; just buy a new one and replace it. When installing, make sure the smooth side of the battery faces down—don’t put it in backward. After snapping the cover back on, test the key by locking and unlocking the car a couple of times to ensure it works smoothly. Try not to keep the key too close to your phone in your pocket, as electromagnetic interference can drain the battery faster. Off-brand batteries from supermarkets will work, but don’t cheap out—they tend to fail in cold weather.

Old driver teaches you a trick: A coin can also open the Yinglang key! Slot a 50-cent coin into the groove on the back of the key, then twist it with a hidden force to open. The battery is a 3V CR2032, available at any convenience store. Last time, my wife installed it upside down by herself, causing the remote to fail—remember, the side with text must face up. After installation, press the cover tightly until you hear a click, which is crucial. By the way, don't stockpile batteries; they expire in three years—all the expired ones in my garage drawer are useless now.

Designers usually hate complex structures, but this key is surprisingly simple. Use the tip of a utility knife to pry open the back cover—it's less likely to damage the paint than a screwdriver. The battery model is CR2032; be careful not to buy CR2025 by mistake, as it’s half a millimeter thinner and may cause poor contact. Once in winter at -10°C, the remote stopped working. I thought it was a battery issue, but it started working again after warming up, making me disassemble it three times for nothing. A reminder for northern drivers: low temperatures can cause a sudden voltage drop in batteries, which doesn’t necessarily mean they’re dead. After reassembly, test the lock button from 5 meters away—if the signal is weak, check the contacts.
