Key problem!

Evening all Work progresses on my newly aquired 240 - the lights, fan heater etc are now working OK. In addition the engine seems fine - 20 miles today without a hiccup - very smooth. Knackered radio removed with blanking plate installed - looks good. Have removed economy (vacum) gauge so of any one want it send me a PM - it is complete with surround and pipe but not the fitting that screws into the manifold. Have fitted the blanking plate supplied by Brens and it looks good. A couple of problems however: The heater still vents hot air even when the controls are turned to the cold setting. I had two keys when I picked up the car, I have lost the one that operates the boot and glove compartment - the remaining ones works the doors and ignition. Can I source a master key via Volvo quoting the VIN number or similar? Otherwise, what do I do - replace the boot lock? At the moment its OK as the central locking opens the boot - however, if there is a problem with this system I wont be able to get into the boot? Any ideas folks?

A volvo dealer can cut you a key from either the VIN or the registration number.

Andrew (UK) has asked for the vacuum gauge so this is no longer available!

Update on my original post - the heater seems to have sorted itself out and is now venting cold air! It made some odd 'gurgling noises' first.
