Turn they key over so you are looking at the side without the buttons on.
Near the blade of the key is a Small slot. Put a small screwdriver (that is about the same width as the slot) into the slot and gently turn it. The Electrics part of the key (the Fob) should pop-out. Pull it out the rest of the way by hand.
The fob opens up, "clam shell" style, by releasing one clip on the side (the other side has two clips, this is the "hinge" side.)
The battery is retained in the back of the fob (the bit without the buttons on.)
Remove the battery and fit a new one (A CR2032, Vauxhall part number 90541381) paying attention to the way up the old one was.
Re-assembly is the reverse of removal, but the fob will only fit into the key one way round.
Once the battery has been replaced it may be required to "reset" the locking/alarm system on the car. To do this put the key in the ignition, turn the key till all the dash warning lights come on, and press the "open" button. The car locks should lock and instantly unlock to show it has worked.
Alternatively call in at your local dealer, ask & pay for a new battery and ask to have it fitted for you. I fit them for free. :)

How do you open the key fob for a vauxhall vectra?
on the key fob, turn the key over so that the buttons are on the back. there is a small groove near the blade/key end of the fob. you can prise this open using a small screwdriver or if you're strong pull the blade/key part outward/away from the fob. the remaining key fob can then be split in two to get at the battery. beware that you only have a very short time to replace the battery or the fob will go out of sync with the car.
