Testimonials
We Are Trusted Over 40 Years
Licensed locksmith service in Lenox Hill since 1984 — protecting Upper East Side residences and medical facilities for four decades. Golden Key: Lenox Hill’s trusted 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.
