Mul-T-Lock and high-security locks in NYC
Bee Locksmith is an authorized Mul-T-Lock dealer and installer. We install and service Mul-T-Lock and other high-security cylinders for buildings, offices and storefronts in New York City and the tri-state area. High-security cylinders resist picking and drilling, and restricted keys limit who can make copies. Our own technicians install them as part of the door and lock, not as an add-on.
