clefty thanks guys, the lock is pretty new, gonna try in daylight tomorrow with some tweezers but am not that hopeful. looks like its a trip to HSS for me..
:D HSS! can i come! well get the biggest grinder in the shop! ..but i think theres a boring alternative :( i think you can phone the council and they come cut it off for you, you just need to provide some ID like a passport when they come do it. Ill try find out more, my mate had to do it.
