    You will need a CR2032 battery, around a £1 on ebay.

    Remove the key and you should be able to pop off the back cover with a small screw driver.

    Oh, don't think you can do those Rick as the key is sealed. Aren't they suppose to recharge automatically when your driving?

    It can be done but it's a bit of a faff apparently
    I understand when sticking back together the use of cable ties can help hold the halves together.

    Mine is like that' but there's no gap where the blade enters the body - as said, charges in the ignition by induction.

    My key is like the one in the top picture ( lci fob with no visible key blade ) and has just stopped working, spare key works fine. Will this be a case of replacing battery or will I need a new fob!!
    Thanks

    If your car hasn't got comfort access then the battery isn't replaceable. I don't know whether it can be broken apart and physically replaced like they do with the old style key in the video above but theres certainly no pop off cover without the comfort access option on those keys.
