Method to replace the battery of BAIC Weiwang M50F remote key: First take out the mechanical key, then pry open the shell along the gap of the remote key housing, and you will see the chip and the battery. Remove the old battery and install the new one. Be careful not to damage the chip when replacing the battery. BAIC Weiwang M50F is an MPV model with a length, width, and height of 4724mm, 1796mm, and 1748mm respectively, and a wheelbase of 2760mm. In terms of power, this car is equipped with two engines, one is a 1.5L naturally aspirated engine, and the other is a 1.3L turbocharged engine. The maximum power speed of the 1.5L naturally aspirated engine is 6000 rpm; the maximum power speed of the 1.3L turbocharged engine is 5500 rpm.
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.
