How to Replace the Battery in an MG Car Key?
2 Answers
To replace the battery in an MG car key, follow these steps: 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 flat-head 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. MG car models include the MG6, MG5, MG ZS, MG HS, MG3, and others. Taking the 2020 MG6 as an example, its body dimensions are: length 4704mm, width 1848mm, height 1466mm, with a wheelbase of 2715mm, a fuel tank capacity of 50 liters, and a trunk capacity ranging from 499 to 1383 liters.
Last time my MG key fob stopped working, it gave me quite a scare. I quickly searched online how to replace the battery. Usually there's a small groove on the back cover of the key - you can gently pry it open using a keyring or small screwdriver, but don't use too much force to avoid cracking it. Inside there's a button battery, typically CR2032 model, which you can buy at supermarkets or auto shops. Remove the old battery, paying attention to the positive/negative orientation - insert the new battery with the positive side facing up. Close the cover firmly, then test the remote unlock/lock functions. I recommend testing the vehicle ignition after battery replacement to ensure everything works before driving off. It's wise to keep some spare batteries in your car - prevents delays in critical moments and makes routine maintenance easier.
