I've got a lock on an old style metal sliding patio door that neither myself or my landlord have the key to.
There is no lock on the door itself but a little box at the bottom of the door with Copydex on the side.
I was just after a bit of advice on what to do:
Would it be best to get a lock pick to pick it and then replace it, can you get generic keys like those for window locks or is there anything else that i can do?
