How to Replace the Battery in a Baojun Car Key?
2 Answers
Baojun car key battery replacement method is: 1. Use a flat-head screwdriver to pry open the key case along the opening line on the side of the key from top to bottom; 2. Remove the key shell with the logo; 3. Locate the battery compartment at the back, then unscrew the screw on the battery compartment; 4. Take out the old battery and replace it with a new one. Baojun's models include: Baojun 730, Baojun 310, Baojun 510, Baojun 530, Baojun 360, etc. Taking the 2021 Baojun 510 as an example, it is a compact SUV with body dimensions: length 4220mm, width 1740mm, height 1615mm, and a wheelbase of 2550mm.
I remember last time when my Baojun key fob ran out of battery, the remote stopped working, and I was so anxious that I immediately searched online for solutions. The back cover of the key is made of plastic, with a small gap along the edge—you can gently pry it open using a coin or your fingernail. Just be careful not to use too much force when prying, or the cover might crack. Inside, you’ll find a round coin-cell battery, usually the CR2032 model. When removing the old battery, remember the positive and negative orientation; place the new battery the same way—don’t reverse it, or the remote won’t work. After replacing it, snap the cover back on firmly and test the unlock button to make sure it’s functioning. The first time I replaced it myself, I was a bit worried about making a mistake, but it only took me a couple of minutes—saving money and hassle. I recommend not waiting until the battery is completely dead; if the remote feels less responsive, go ahead and replace it. The batteries are cheap and available at convenience stores. Stay patient during the process, and use fine tools to avoid scratching the key’s surface.
