Snapping your key in the lock is a classic nightmare scenario. With the right tools though, it’s often possible to remove the broken metal from the cylinder, and then access the property, without damaging the lock. If you have a spare, you can the make new duplicates of course. If there has been unfortunate damage to the lock in the process we can usually replace the cylinder on the same day.
