I know this topic has be covered however i seem to be stuck half way. I have a Ford Ka 1999 (V) in with lost keys. got a new ecu, transponder etc. I have cut the end of the barrel off with hacksaw and removed the tumblers. The lock will now turn but i cant seem to see any way of removing the barrel. I have turned to position 1 and understand there is a grub screw or similar somewhere??? can anybody help please???
