2 Answers
To replace the battery in an Envision key fob, follow these steps: 1. Press the button on the transmitter to eject the key. 2. Use a flat tool to insert into the bottom of the transmitter and separate it into two halves. 3. Press the battery and slide it toward the bottom of the transmitter to remove it. 4. Insert a new battery with the positive side facing the back cover. Press the battery down until it is securely in place. Use a CR2032 or equivalent battery for replacement. 5. Reattach the battery cover to the transmitter. Important notes when replacing the battery: Avoid touching any circuits inside the transmitter during the replacement process, as static electricity from the body may damage the transmitter. The battery model for the Buick Envision key fob is CR2032.
I replaced the battery in my Envision key fob last year, and it was actually quite easy. There's a small notch on the side of the key - just use a coin or flathead screwdriver to twist and pop open the back cover. The battery is a common CR2032 coin cell, which you can buy at any supermarket for about five yuan. When removing it, remember which way the positive side was facing (usually the side with text faces up). The trickiest part is the rubber gasket that tends to fall out - make sure it's properly seated before reassembling, or the key won't be waterproof anymore. After replacement, test by pressing the buttons a few times. If your older key fob doesn't respond, you might need to reprogram it - there's a tutorial in the Buick app.
