How can I change battery for my key? I paid £150 for a key for my last 307 and was told I may mess the workings up if I open the housing!
Please help!!

Take the philips screw out of the key.
Using a flat bladed screwdriver open the key apart - there will be an opening on the bottom of the key
This is important part
Carefully open the key and don't drop, lose or put the circuit board back in incorrectly
Doing so will mean you wont be able to start your car.
When replacing the battery make sure you remember which way it goes back in, as it'll only work in one way.
Refit in reverse order.

2nd option: take it to a garage and get them to fit it,
