Part: Key
Operation: How to replace the battery of a Smart car.

Replacing the battery of a Smart key is a very simple operation that can be done independently, thanks also to our video guide. Let's start the key replacement by removing the metal security key located inside the remote control. To do this, we simply need to pull it out. Once the security key is removed, we can proceed to open the remote control. To open the remote control, we simply need to pry on the bottom right side. Once the remote control is open, we can remove the microchip and the battery. We insert the new battery and close the remote control.
