I've been using this Buick Envision key for several years and often encounter battery replacement. There's a small notch on the back of the key. You can gently pry it open with a flat-head screwdriver or a thin coin. Inside, there's a CR2032 button battery—make sure not to reverse the positive side when replacing it. Align the new battery exactly as the old one was. After replacement, press the shell firmly until you hear a click, then remember to test the remote function by pressing the lock button. Sometimes, after prolonged use, the key's clips may loosen, so I take the opportunity to clean out dust to prevent poor contact. The battery can be bought for just a few dollars at supermarkets or online—keeping a few at home saves you from last-minute errands. Be careful not to use wet hands to prevent short circuits, and handle gently to avoid damaging the plastic parts. I make it a habit to check regularly to prevent suddenly being unable to lock the car door due to a dead battery—it's both safe and convenient.
