I've been driving my BMW X1 for a few years, and the remote key battery died. Replacing it myself was super easy. First, take a small tool like a coin or screwdriver, find the small groove on the back cover of the key, and gently pry it open. Don't use too much force to avoid scratching the plastic shell. Second, inside you'll see the button battery, model CR2032. Remember, the battery has a positive and negative side—usually, the round side faces up, meaning the positive side is down. Use tweezers to remove the old battery and replace it with a new one, which you can buy at the supermarket for about three yuan each. Third, after placing the new battery, align the cover and press it back into place, applying some force to ensure it's snug. Then, you can use the remote to lock the car doors—it'll work perfectly with just a press. A reminder: the key battery usually needs replacement every two years. Avoid storing the key in damp places to prevent leakage. My key has been working flawlessly for this long, and I saved 200 yuan in labor fees compared to going to the 4S shop.
