How to Start an MG Car When the Key Fob Battery Dies?

Disassemble the key fob, purchase a new battery matching the button cell model, and replace it to resolve the issue. Some models have a sensor near the start button. Simply bring the key fob close to the start button to start the vehicle. Some models have a dedicated key fob sensing area on the center console. Placing the key fob in this area allows the vehicle to start normally.

If your MG car key runs out of battery, the first step is to use the physical key inside to open the door—usually there's a small button on the key fob; press it to pull out the key. Once inside the car, don’t rush to start it. Modern MG models like the MG ZS or HS have a designated induction area near the start button. Place the dead key against it (e.g., pressing it close to the button), then press the button to start. If it doesn’t respond, check the manual for the exact induction spot or try a spare key. Having driven an MG for years, I’ve faced this situation—staying calm is key. It’s wise to keep a spare button battery at home and replace it when the remote’s range shortens, preventing emergencies. This ensures timely starts and extends the key’s lifespan.
