  You may need to use these: http://shop.eurobatteries.com/images/ipod_open_tools.jpg
  
  Try going into your local mobile phone shop, they should be able to do it for you.

  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.

  Thank you both for your advice :) As I only have a short time to get new batteries in I think its best to go somewhere, as Im not sure on the size they need.

  You can open and look at the battery needed or even take out and pop back in if you have to

  They may go out of sync, but its quite easy to sync it back up if i remember correctly.
  
  If you have a fob which is not programmed to any car, you put the key in and turn it round 4 or 5 times...well, thats how you got Transits to work anyway.

  As above split key apart.ie metal key and buttons apart.
  then where they meet you open the buttons its quite tight there you will see battery its a cr2032 battery.
  Once replaced it wont work.
  Go to car open door with key alarm might sound.
  Put key in ignition and try to start car i think it starts and also sets key .
  Close door and try to lock with buttons should work it did for me.

  Thats great, we have done both keys, the one that I have been using instantly worked but the other just wont zap the car so I will try this out in the morning see if it will kick start the key back :)

  The battery you need is a CR2032 and you can get them very cheap on Amazon (I paid less than a pound for two, including delivery). It really wasn't that tough to get this done on my 2002-2009 model Vectra key. You need a small flat-blade screwdriver (3 or 4mm wide) to put in the notch and twist, as per the instructions above, which will move the metal part of the key off the body of the fob. Then don't be afraid to split the fob into two halves (it's pretty easy if you just give it a go) and you'll see the battery. Look to see which side of the battery goes up and which goes down, then swap the new one for the old one and put it back together. Total time to do probably around two minutes.
