I recently replaced the battery of my Baojun remote key by myself, and it felt quite easy. First, prepare a small flat-head screwdriver or a coin because there's a small notch or clip on the back of the key. Gently pry it open without using too much force to avoid breaking it. Inside is a coin cell battery, usually the CR2032 model, which you can buy at a supermarket for just a few bucks. When removing the old battery, pay attention to the positive and negative markings, and place the new battery in the same orientation. Reassemble the cover and press the test button to check the unlocking function. If it doesn't work, open it again to check if the electrode contacts are clean—avoid touching them with your fingers to prevent oil residue from affecting performance. After one attempt, I learned my lesson: replace the battery every two years to prevent failure. Doing it yourself saves time and money while also teaching you useful life skills, giving you confidence in emergencies. I recommend keeping a spare battery in your car for convenience in urgent situations.
