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.

I often replace the battery for my car key myself, and the steps for the MG ZS key are not complicated. Just prepare a small pry tool or use the edge of a nail clipper. There is usually a designed opening on the back of the key. Gently insert the tool and pry open the shell, moving slowly to avoid damage. The battery inside is mostly the CR2032 model. After removing the old one, simply replace it with a new one, making sure not to reverse the electrodes. After closing the key, test if the unlock button works. If it doesn't, check if the contacts are oxidized. It's recommended to buy genuine batteries, available at supermarkets or auto parts stores—don't go for cheap ones. After replacement, maintain the key by cleaning off any dirt. If you notice the signal distance shortening, it's a warning to replace the battery.

Changing the car key battery for the first time is like opening a small box. For the MG ZS key, gently pry the edges—it's easy. The commonly used CR2032 battery is compact and readily available. When replacing, ensure the electrodes are aligned correctly to avoid wrong orientation; it's a simple task that takes just a few minutes. After completion, press the buttons to test—if the light comes on, it's successful; otherwise, repeat the steps while paying attention to cleanliness. I keep a spare battery with me for emergencies, ensuring a more worry-free driving experience.

The MG ZS key uses a CR2032 lithium battery with a standard voltage of 3V. When replacing the battery, choose a plastic pry tool to prevent scratches. After prying open the casing, remove the old battery and note its position and orientation. When installing the new battery, ensure the positive side faces upward for good contact. After installation, test the remote control's functional range. If the distance is short, it may be due to battery quality or contact issues—clean the contacts if necessary. A normal battery lasts one to three years; regular checks can prevent malfunctions. Also, keeping the battery compartment dry can extend its lifespan.
