How to Replace the Battery in a Baojun 630 Car Key?

[DeJohn]

Prepare the necessary tools: the key, a screwdriver, and a battery. It's important to ensure the battery is the same model as the original one in the key. Slide the latch at the bottom of the car key to the right to remove the mechanical key. Insert the screwdriver into the hole on the left side and rotate it clockwise. When you hear a "click" sound, remove the screwdriver and pry open the back cover of the key. After removing the back cover, use a pin to pry out the old battery and replace it with a new one. Be careful not to reverse the positive and negative terminals of the battery. Once the battery is replaced, close the back cover and reattach the mechanical key.

I've replaced the battery for my Baojun 630 car key several times before, and it's quite simple. First, use a pointed tool or a small coin to gently pry open the small groove on the side of the key, being careful not to damage the plastic casing. Once the back cover is open, you'll see the old battery, typically a CR2032 coin cell. Remove it while noting the positive and negative positions. Align the new battery and press the back cover firmly back in place. After replacement, test the unlock function by pressing the remote button. These batteries last about one to two years, and buying them online costs just a few yuan each—much cheaper than spending dozens at a 4S shop. DIY is very convenient, and I recommend checking them regularly to avoid sudden power failure. Don't worry, take your time, and you'll get the hang of it after a few tries.

As a young person with my first car, I was a bit nervous the first time I changed the battery for my Baojun 630 key. My friend taught me to locate the small slit on the key, then use a flathead screwdriver or the key's own metal piece to pry open the back cover, being careful not to break the plastic clips. Inside, the old battery is revealed, usually a CR2032 model, which can be easily bought at supermarkets. Remove the old battery and replace it with a new one, making sure the positive side faces up, then press the back cover back into place with your fingers. Immediately test the remote to unlock the doors or trunk to check if it works. If there's no response, the battery might not be installed tightly or the model might be wrong—open it again to confirm. The whole process takes about five minutes, saving money and time. Battery aging typically requires replacement every two years, so keeping a spare new battery in the car adds peace of mind. The first time might make your hands shake, but with practice, you'll gain confidence.

Replacing the battery for the Baojun 630 car key requires caution, especially at my age where safety is a priority. First, check for a small opening on the edge of the key. Use a fine-tipped tool to gently pry open the plastic back cover. Avoid using excessive force to prevent cracking the casing. Remove the old battery, which is typically a CR2032 model, then align the new battery with the negative terminal and insert it. Close the back cover and press firmly. After replacement, immediately press the lock button to test the remote function. Battery life generally lasts one to three years, so replace it promptly when it ages to avoid malfunctions that could disrupt your car use. If you're hesitant to do it yourself, you can visit a roadside repair stall for assistance at a low cost. Remember to proceed slowly and take care not to damage the key.

I have plenty of experience changing car key batteries. The Baojun 630 key has a designed groove, so you can easily pry it open with a coin or nail clippers. After removing the back cover, you'll see the old CR2032 battery. Make sure not to reverse the positive and negative poles, otherwise the remote control may malfunction. Replace the old battery with a new one, then gently press the cover back on. To test, press the function button near the car to confirm the locking works properly. It's recommended to buy branded batteries for better durability, which are generally available at hardware stores. If the key doesn't work after replacement, it might be due to poor battery contact or water damage, requiring cleaning of the contacts. Changing it yourself saves time and money. The frequency depends on usage, and the operation is simple, taking just a few minutes without needing professional tools. Be careful not to operate in damp places and keep everything dry.

As a mom who frequently shuttles kids around, I prefer changing the battery for my Baojun 630 car key at home.

When buying new batteries, I recommend choosing authentic ones from supermarkets or auto parts stores for affordability and convenience. DIY replacement saves a trip to the repair shop; prioritize safety and take your time without rushing. Proper key maintenance ensures smooth daily commutes.
