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.
