High-Security Locks

When you live or do business in NYC, the standard $25 hardware-store cylinder is the weak link in your security: building masters, bumping, picking and even lock-snapping take seconds. High-security locks fix that by combining UL 437 / ANSI Grade 1 hardware with restricted, patent-protected key blanks that cannot be copied at a kiosk. SwiftLocksmith specifies and installs the four brands that dominate NYC's most security-conscious buildings: Medeco (Maxum, Classic, M3) for sliding-pin and rotating-pin pick resistance favored by Upper East Side co-ops and law firms; Mul-T-Lock (MT5+, Interactive+, ClassicPro) for telescopic-pin technology and bump immunity used in brownstones and high-end retail; Abloy Protec2 for the disc-detainer mechanism preferred by jewelers and museums; and Schlage Primus for sidebar-controlled federal-grade keying common in commercial Manhattan offices.

Each cylinder is keyed to your unique restricted blank: only you (or a person with your written authorization plus a notarized signature card on file with us) can ever order another copy, which means a contractor, ex-partner or former employee can't quietly clone your key. We install them on residential entry doors, apartment front doors, brownstone vestibules, retail storefronts, server rooms and safes. Most installs swap directly into your existing mortise or rim hardware so there is no door modification, and the work typically takes 30–60 minutes per cylinder. We also build full master-key systems on these platforms, perfect for landlords and small commercial buildings that want one master to access every unit while each tenant carries a unique key that can be revoked.

Investing in high-security cylinders also frequently lowers commercial insurance premiums (we'll provide the install certificate insurers ask for). Pricing starts at $225 per cylinder installed; complete master-key plans are quoted on-site after a free security assessment.
