Does anyone know how to replace the battery in the key I have opened the key but the battery appears to be attached permanently to a silver spiral piece .
Any ideas ?

Thanks
I've just done this and my key needed to be re-programmed with the car, although my lock button is no longer working. Unlock and boot release are working fine though.
Perfectly true and should be the last port of call, but regardless of this some of the rechargeable batteries do die and have needed to be replaced. Some of them are well over a decade old now.
