Baojun 630 Car Key Replacement Method: 1. Flip the small switch on the key to remove the mechanical key; 2. After pulling out the mechanical key, there is a gap around the shell; 3. Use a screwdriver or other thin tool to pry it open, rotating along the gap for a full circle; 4. Separate the key, remove the old battery, and replace it with a new one to complete the process.

Last time I helped my dad replace the battery in his Baojun 630 key, I figured out a few tips: First, locate the small notch on the side of the key and gently pry open the cover using nail clippers or a small screwdriver. Note that the silver coin battery inside is a CR2032 model, which you can find at the watch counter in supermarkets. When removing the old battery, avoid using metal tools to pry it out—just use a toothpick to push it out from the side. When inserting the new battery, make sure to check the orientation; the side with the '+' sign should face upward. When putting the cover back on, listen for a 'click' sound to ensure it's securely fastened. The whole process takes less than three minutes, but if your hands are sweaty, remember to dry them first, as the battery is sensitive to moisture. If the key still doesn't work after replacement, it might need to be reprogrammed, in which case you'll need to contact the 4S dealership.

After repairing cars for five years, I've seen too many cases of keys being damaged during disassembly. The Baojun 630's straight key is quite simple: pinch both sides of the key and pull firmly, and the casing will split open from the middle. Focus on the shiny CR2032 battery in the center of the circuit board—you can buy two for ten yuan at the supermarket. When removing the old battery, be careful not to scratch the golden contacts beside it. Press the new battery in with the printed side facing up. Just align the casing and press it back together with your palm; no tools are needed at all. Remember to avoid metal objects throughout the process, as static electricity can fry the chip. I usually advise the owner to clean the blackened battery slot while they're at it—oxidized copper contacts can affect connectivity.

As a female car owner, I'm always afraid of breaking things. Changing the battery in the Baojun key is actually very safe: just prepare a 1-yuan coin and a cotton pad. Insert the coin into the gap at the tail of the key and twist to open it, then use the cotton pad to remove the battery to prevent static electricity. Remember the battery model is CR2032—don't buy the wrong one. When installing the new battery, make sure the side with the engraving faces upward, and you'll hear a crisp 'click' when it's properly in place. After changing it, I reinforce the seam with transparent tape to prevent water damage on rainy days. The whole process is even simpler than changing a SIM card, and the moment the key light turns back on feels incredibly rewarding!
