To replace the battery in the key fob of the latest model Porsche Cayenne, you need a plastic lever to help open the housing. Alternatively, you could use a flathead screwdriver, but since it's metal, it might damage the plastic of the fob. First, remove the blade of the mechanical key, then use the lever to remove the side parts of the housing.

Using this plastic lever, you can rotate the cover of the battery compartment to open it and finally access the battery.

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.
