How to Replace the Key Battery for Envision?
2 Answers
To replace the key battery for Envision, follow these steps: 1. Use a screwdriver to pry open the gap on the side of the key; 2. Bend the back cover toward the closed end to remove it; 3. Take out the old battery and replace it with a new one of the same model; 4. Reassemble the key in the reverse order of disassembly. Taking the Envision 2021 model as an example, it is a 5-door, 5-seat MPV under the Buick brand, with body dimensions of 4694mm in length, 1839mm in width, and 1686mm in height, a wheelbase of 2750mm, a fuel tank capacity of 66 liters, and a curb weight of 1610kg.
I also encountered a dead key fob battery when driving my Envision before, and changing the battery myself went smoothly. Find a small screwdriver or thin tool, gently pry open the small gap on the back of the key fob—there’s usually a small notch designed there. Don’t use too much force to avoid scratching the casing. Inside, you’ll see a coin cell battery, typically a CR2032 model. Before removing the old battery, note the positive and negative polarity to avoid reversing it. Just insert the new battery the same way. When closing the key fob, press the clips firmly and test the buttons a few times to ensure they unlock the car door properly. The whole process takes less than five minutes, and the battery costs just a few dollars at a supermarket or online—it’s good to keep a spare handy. I also recommend regularly checking the key fob’s waterproof seal and battery life. The Envision’s key fob is well-designed, but with prolonged use, the battery drains quickly. Doing it yourself saves the cost of a dealership visit.
