Car remote keys have functions such as locking/unlocking doors, locating the car, and setting anti-theft features for the vehicle. The method to replace the battery of a Baojun remote key is as follows: 1. Remove the mechanical key. 2. Use a flat-head screwdriver to pry open a small gap from the side seam of the key, then gradually pry open the seam along the gap. Note: after opening one side a bit, pry from the other side, and finally open it completely. 3. Use the flat-head screwdriver to remove the old battery and insert the new one. Note: the positive side (+) of the battery should face downward. Then reinstall the circuit board into place, align the key cover properly, and press firmly with your hand until you hear a click sound indicating it's secured. After securing, check the seam; if the gap is small, the replacement is successful.

To replace the battery in your Baojun remote key, I personally think it's safer to start by understanding the key's structure. Typically, Baojun key casings have small gaps near the buttons where you can gently pry them open using a small screwdriver or coin—just be careful not to apply too much force to avoid scratches. Inside, you'll usually find a coin cell battery, often a CR2032 model, which can be easily purchased at supermarkets or online for just a few bucks. When removing the old battery, pay attention to its orientation (positive/negative sides), and insert the new battery the same way. After reassembling the casing, it's best to test the buttons for responsiveness to ensure they can lock/unlock and start the car. If they feel unresponsive, there might be poor contact—reopen and check. Also, note that different Baojun models may have slight variations in key design; for example, older 510 keys and newer RM-5 keys differ in casing thickness, so pry more carefully to avoid breakage. Always carry a spare battery, and replace it promptly if you notice reduced remote range to avoid getting stranded.

My last experience changing the battery in my Baojun car key was quite amusing. After years of use, the buttons were getting increasingly sticky, so I used a paperclip to pry open the back cover. The first attempt went awry and nearly broke the clip. Later, I watched a video tutorial and realized I should start from the side gap—it popped open with a gentle pry. The battery inside was a CR2032. When removing it, I made sure to note its orientation so the new one could be installed exactly the same way. When putting the cover back on, I pressed firmly until I heard a click. After the replacement, the unlock response was much quicker. Just remember not to do this in a damp environment—wet hands could cause a short circuit. Not only did I save money, but I also saved the trip to the shop. If you don't have the right tools, you can borrow a flathead tool from a friend. I recommend checking the battery every two years to extend the key's lifespan and avoid unexpected issues.

The steps to replace the battery in a Baojun key are simple: First, locate the gap on the key and use a tool to pry open the shell. Remove the old battery inside and check the model (CR2032), then purchase a new one and insert it. After reassembling, press firmly and test. Be careful not to use excessive force.
