Last time my BAIC Weiwang M50F remote key wasn't working, so I figured it was time to change the battery. There's a thin seam on the back of the key, so I carefully pried it open with a screwdriver from home—don't use too much force, or the shell might crack, which would be troublesome. Inside was a small round CR2032 battery, which costs just a few bucks at the supermarket. When replacing it, remember to place the new battery with the positive side facing up, or the remote won't work. After reassembling, I tested the lock/unlock function, and everything was back to normal. I recommend changing the battery once a year—it usually lasts one to two years, so keeping a few spares at home saves money and hassle. Avoid exposing the key to high temperatures to extend the battery life.
Replacing the battery for the BAIC Wevan M50F key isn't complicated at all, I often help my neighbors with this. The key casing is mostly secured with clips, just use a small screwdriver or thin tool to pry it open from the gap. The battery is a CR2032 model - when removing the old one, pay attention to the positive/negative polarity to avoid mixing them up. Align the new battery properly, press it firmly into place, then close the cover securely. Test the remote by pressing buttons a few times to check if the indicator light works - don't overlook this step. If the casing feels too tight, don't force it open as you might damage the internal circuits. Battery lifespan depends on usage frequency, typically requiring replacement every two years or so to prevent malfunction - this is the safest approach. Always choose reliable battery brands to avoid quick failures and recurring issues.
I just replaced the battery in my BAIC key fob myself, and it was quite easy. There's a seam on the key fob - just pry it open with a small tool. The small battery inside is a CR2032, which you can find at any supermarket or hardware store. When replacing the battery, make sure to align the positive side correctly and don't put it in backwards. Gently snap the cover back in place and test the remote to ensure it's working properly. The whole process is very simple and takes just a few minutes. I recommend wearing gloves during the operation to prevent static electricity and avoid accidental damage. Using a slender screwdriver makes it easier to find the seam. Take your time and proceed step by step.
