How to Replace the Battery in a MG ZS Key?
2 Answers
Method for replacing the battery in a MG ZS key: 1. Locate the silver button at the top of the car key; 2. Press the button, and the mechanical key will automatically pop out; 3. Once the key is open, you will see a gap in the middle. Use a flathead screwdriver to slide along the gap and pry it open; 4. After opening the back cover, you will see the battery panel. Remove the old battery and install the new one. The MG ZS is the first internet SUV model under the MG brand. In terms of body dimensions, it measures 4323mm in length, 1809mm in width, 1653mm in height, with a wheelbase of 2585mm.
Last time my MG ZS key suddenly stopped working and the remote couldn't lock the doors, I suspected the battery was dead. I replaced the battery myself, and it was quite simple: first, find a small gap on the side of the key case, then gently pry it open with a small flat-head screwdriver or a credit card—be careful not to use too much force to avoid breaking the clips. Inside, there's a CR2032 coin cell battery. Remember the orientation of the old battery when installing the new one, with the positive side (marked with a +) facing up. Before inserting the new battery, wipe the metal contacts with a dry cloth to prevent poor contact. After replacing it, close the case firmly and test the key buttons—if the red light flashes normally, you're good to go. I later stocked a few of these batteries in my car so I can replace them immediately if the key buttons become unresponsive, avoiding any roadside panic. The battery typically lasts about two years. After replacement, check the case seal to ensure no dust gets in, as it can affect the battery's lifespan.
