You should be able to bend the sawn downwards to allow it to split.

You used to dismantle the lock, but now you have to reassemble it.Push the new cylinder or barrel back through the door and screw it to the back plate using the long screws you took out.Then slip the lock box over the shank and wiggle it back into place.Use the side screws you took out first to screw the lock box back on.
