If the remote key has lost its codes and can no longer open and close the vehicle, you can reprogram it by following the procedure below: enter the cabin and sit in the driver's seat, insert the key into the ignition switch and start the engine. Locate the buttons on the key for opening and closing the doors, and press them in sequence (first the unlock button and then the lock button) at least five times.

At that point, the key will be reprogrammed, and you can turn off the engine. Finally, remove the key and exit the cabin to test its functionality.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
