Car keys currently available on the market mainly include mechanical and electronic types. 2. Mechanical car keys are the most traditional and widely used type, with relatively simple functions, only featuring lock and unlock buttons. However, mechanical car keys have a lower failure rate, require less frequent battery replacements, and are easier to maintain. 3. Electronic car keys are a new type of car key with more functions. In addition to locking and unlocking, the display screen of an electronic car key also integrates vehicle information such as fuel consumption, driving range, and door status.

I've been driving a Baojun car for several years and have replaced the key fob battery two or three times. You should change it when the remote control distance becomes shorter or the buttons stop responding. First, find the correct battery model—most Baojun keys use CR2032 coin batteries, which are available at supermarkets or auto parts stores. Be careful when opening the key; the back cover can usually be pried open or unscrewed with a small flathead screwdriver. Avoid using excessive force to prevent scratching the plastic shell. When removing the old battery, pay attention to the positive and negative markings—align the "+" side up or down as it was. After taking it out, check for any corrosion. Insert the new battery in the same orientation, gently close the cover, and test the remote function. It's recommended to check the battery every two years. Doing it yourself saves over a hundred yuan compared to going to a 4S dealership and prevents unexpected power loss that could leave you unable to unlock the car. The whole process takes about five to six minutes. Beginners can search for tutorial videos online—all you need is a small flathead screwdriver. Just remember to test it before regular use.
