I called Global Locksmith Service and told John that I had a disassembled, removed deadbolt on my back door and a patio door lock that I thought couldn't be repaired. He said that he could come by in the afternoon. He arrived and went right to work on the disassembled deadbolt and reattached it to the door. After finishing, he sprayed it with silicone and tested the key on both sides of the door to assure that the key was properly fitted and would open from both sides. He then looked at the patio door and said that he could, indeed, fix the lock on that as well. He repaired the patio door lock and sprayed it with silicone to assure easy locking. I'm very pleased with his work and I would call him again.
