If you think it’s time to replace the remote battery for your Jeep Grand Cherokee because it only works from very close range or not at all, you’re in the right tutorial. Before you begin, you will need a new C2032 3V battery and a slightly robust flathead screwdriver.

The first step is to remove the metal ignition key from the body by unlocking the small clip on the remote. Next to the metal key housing, there is a slot where you should insert the screwdriver to lever it open and separate the remote into two parts.

Unlike many other remotes, the battery is not housed on the motherboard but on the other half. The final step is to remove the old battery with the screwdriver and reposition the new one. Ensure that when you finish the operation, you reassemble the two sections of the key correctly without leaving any gaps.

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.
