It's a simple DIY job that only requires popping off your fob's rear panel and switching out the coin cell battery.

If you've got a more recent fob, though, you will likely have a non-rechargeable CR battery, which will need replacing periodically. Many of these fobs have rechargeable batteries designed to be topped up automatically during use as soon as it's put in the ignition slot, it starts charging. If you've got a key fob that you have to insert in a slot on your BMW's steering columnyou might be able to skip this step. If it's not working, it could just be that the battery has run out. Before shelling out on a new remote key fob, it's worth making sure your existing one really needs replacing. Maybe your existing key is just damaged, and you need something fresh. Maybe you want a spare in case you lose your primary key, or perhaps you share your BMW with a few family members and want everybody to have a key of their own. But for all this convenience, they can be a real pain to get copies of. Modern remote keys have plenty of security benefits and make it easy to get into your car and hit the road - particularly if your BMW or MINI has the Comfort Access feature.

Where did you get this fob from then? Its a long story I had to get a new key and all i had to do is push the key into the slot, hold it for 20 seconds and thats it. What I meant to say was how to program the keys to actually start and run the car. Thanks for the info Nikki but I think we're talking about 2 different things. You use the left stalk thing sorry I'm not very technical and there is a button that goes up or down on it and a button that goes in on it. Does anybody know how this can quickly be done?
