Licensed locksmith service in Marble Hill since 1984 — protecting upper Manhattan’s northernmost neighborhood for four decades. Golden Key: Marble Hill’s locksmith.
Needed urgent lock change for our DUMBO store. They used Mul-T-Lock cylinders for extra security. Highly recommend.
Kenny replaced weatherstripping on a revolving door at our Upper West Side building. Immediate improvement. The lobby feels like it's summer again during the dead of winter.

Mark came to our apartment after we couldn't lock the door. He replaced the internal cylinder and made it safer with a Mul-T-Lock upgrade.
