Locksmith job in Parkchester Bronx. Her problem was that she needed some locksmith repair done on her lock which she said refuse to open leaving her locked in the apartment. When we arrived, we carefully studied the lock. There were three things we thought we could do. We had an option of changing the mortise mechanism, the knob or change the mortise itself. We also had an option of installing a new mortise lock. We checked the screws holding the lock cylinder and realized that they were loose. We removed the faceplate and located the two loose screws which we replaced. We aligned the new screws with the center of the mortise cylinder and tightened them. We replaced the faceplates and screwed them in place. We tested the lock to see if it was working and we realized that we had done a wonderful job. The lady praised us for our work and we left.
