Going to try to explain this the best I can until I can go and get some photos' of the lock.
I need to get the lock off the bolt to replace the bar that was fitted as an extra support for the engine.
It's a cylinder (alloy?) with a flush cap. Looks like the key goes into a cut out between the cap and the cylinder body. Has a black rubber cap if that helps.
Are these like the classic alloy wheel locks and every key sold fits ever lock? Or am I going to have to cut it off?
Will get some photos' as soon as I get time to go up to the RIB (really wish I'd dug my heels in over it living in the front garden
