Received a call from a distressed man who was locked in his house.  On arriving at his house and opening the door the man threw his arms around me and thanked me so much for my quick response. Quantum locksmiths carry a large selection of locks and tools for most eventuality. The lock was replaced on the spot and as the man was less privileged a free security check of all door and windows was conducted for his own safety. Sherborne in Dorset.
