My garage lock doesn't inspire me with confidence. The door is a standard up and over, and there is a metal latch on each side that clicks past a rail on the vertical part of the frame. These latches are connected by a wire to a handle in the centre of the door which you turn to release the latches. It's only the central handle that has a lock, and I don't think it would take much to bypass.
Does anyone have any ideas on what to use to beef this up?
