To change the battery in the Toyota Prius remote, note that the remote has a narrower top and a wider bottom. The wider part contains the security key, which you should remove first.

You can use the key to split the remote shell in two (however, a small screwdriver or plastic spatula is recommended). The shell contains the chip, which also houses the button battery.

The battery is a CR 2032, which you can find for a few pounds at any supermarket or newsagent. Remove it with the small screwdriver, and replace it with a new one, paying attention to the polarity.

Close the shell, insert the security key, and you're done.

Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
