Well I'm feeling a little stupid now!!

The AA man was with with within 25 minutes, and
within three minutes he had the door open, the battery on booster, with the engine started!!!
Although the buttons of the locks had not risen from the "locked" position, making me think the car was still locked, in fact when I had broken the key yesterday in the lock I had in actual fact unlocked the system. I had just not tried to lift the door handle!

So of course, the AA man just lifted the door handle, went in to release the bonnet catch and in the blink of an eye the booster was on with the engine started.

I really didn't believe, and still don't, how all the buttons were down but the door could be opened!!

Oh well, something learn't, and I got the kind AA man to remove the boot light bulb so if the boot is accidently left open the battery cannot be drained.

Thanks for all your help though guys!!
