Baojun remote battery replacement method is: 1. Locate the plastic button on the head of the car key and pry it open to remove the metal mechanical key; 2. Use the metal mechanical key or a flat-head screwdriver to pry open the plastic shell of the car key, revealing the battery inside; 3. Replace with a new battery, then reassemble the car key by reversing the disassembly steps. Taking the 2021 Baojun 530 as an example, its body dimensions are: length 4690mm, width 1835mm, height 1750mm, wheelbase 2750mm, fuel tank capacity 52l, and curb weight 1465kg.

I just helped my neighbor replace the battery in their Baojun key fob, and it was actually super simple. Look for the small groove on the side of the key, insert a coin, and twist to pop it open. Make sure to note the orientation of the old battery (positive/negative sides). The new battery should be a CR2032 model, which you can find at any supermarket. After installing, don’t rush to close the cover—stand near the car and press the unlock button a few times to test the response. Oh, and avoid touching the metal part of the battery directly with your fingers, as sweat can affect conductivity. The whole process takes about three minutes and saves you 80 bucks compared to going to a repair shop. Wipe the key fob casing with a damp cloth before reassembling—this makes the buttons more responsive.

Last time I replaced the remote control battery myself, I noticed a few key points. First, gently pry open the back cover along the key seam, avoiding excessive force to prevent the clips from breaking. Inside the battery compartment, there are + and - symbols indicating the corresponding electrodes; the Panasonic CR2032 coin cell battery should be placed with the positive side facing up. When testing, press the buttons multiple times from different angles, as sometimes the issue lies with the car door receiver. I also placed a thin piece of paper in the battery compartment to prevent loosening, which works particularly well for older keys. Be careful not to get any water on the components during the process, as electronic parts are sensitive to moisture. If you really can't manage it, just go to the auto parts market to buy a battery and have someone help you replace it—it only costs five yuan.

The worst thing when replacing key fob batteries is scratching the shell. I prefer using a nail file to pry open the back cover - you can buy one for pennies at a hardware store. Before disassembling, take a photo of the old battery position to avoid installing it backwards. Purchase Panasonic or Philips CR2032 batteries at convenience stores. After installation, press the unlock button - if the red light turns on, it means success. If it doesn't work, don't panic, it might be because the battery insulating tab wasn't removed. If the key fob shell clips break, use super glue (502) to attach an old steel ruler as reinforcement. Remember to regularly clean dust accumulation inside the key fob.
