Yes, you can almost always change the battery in a key fob for a Chevrolet Malibu yourself. It's a straightforward DIY task that takes just a minute or two and costs only a few dollars for a new battery. The specific battery type and replacement method depend entirely on your Malibu's model year and the style of your key fob.
For most modern Malibus (approximately 2016 and newer) with the rectangular "switchblade" or separate smart key fob, the battery is a standard CR2032 3V coin cell. To access it, look for a small release latch or a seam you can pry open carefully with a flat-head screwdriver or a coin. Older models (roughly 2008-2015) might use a different battery, like a CR2016, so it's best to check your owner's manual or the old battery itself.
The key is to work gently to avoid damaging the plastic housing. Once open, note the orientation of the old battery (the positive ‘+’ side facing up) before inserting the new one. After replacement, test all the key fob's functions—lock, unlock, and trunk release—immediately. If the remote still doesn't work, ensure the battery is seated correctly and that the contacts inside the fob are clean.
