Lockey M220SN Mechanical Keyless Deadbolt Satin Nickel

Product Description

The LOCKEY M220SN is a mechanical keyless surface mount deadbolt finished in satin nickel. It operates without keys or electronics, relying on a pushbutton combination mechanism to control access. The deadbolt mounts directly to the door surface, making installation straightforward without requiring a mortise pocket or cylindrical bore. At 4.4 inches long, 3.6 inches wide, and 1.8 inches tall, it is compact enough for residential doors, gates, and light commercial entryways. Weighing 0.75 pounds, the unit is lightweight yet provides the positive locking action of a deadbolt. This lock is installed by locksmiths, general contractors, and experienced DIYers working on access control upgrades.

The M220SN suits applications where keyless entry is preferred but battery-powered or wired electronic hardware is not practical or desired. Typical install scenarios include residential side doors, utility room doors, pool gates, fence gates, and secondary entryways. The satin nickel finish blends with standard door hardware in both residential and light commercial settings. No wiring, programming, or power source is required, making it a low-maintenance access control solution.
