Ok, so I cut my key apart, (and my thumb), got the guts out of it and went out to the car and hey presto, the damn thing works everytime! put it back in the casing and no go, well worked once or twice. Take it out of the casing and it works faultlessly. Go figure?
I guess Ill change the battery as what else could I do.
Thanks again for all the help everyone.
Ben.
