I was so impressed with this locksmith. I called him when our front door knob came out of the door. The locksmith answered and was over at my apartment within a few minutes. He took a look at the door and the lock and I learned that the lock was broken in two places. He had a part back at his place that would fit it and when he came back, he had it installed within 15 minutes. Fast, courteous and an all over nice guy. I would definitely recommend Chinatown Lock & Key locksmith to any of my neighbors.
