how do i change battery in key fob?

As you look at the fob where the vauxhall sign is you will see a split in case.Put thumbs either side of slot where key sits in, and push thumbs in opposite direction.The the part of case below split will detach its self. A bit like opening a sea shell.

Should be able to slide the top part of the key. May need a small screwdriver to put in the groove.
