The LOCKEY 2900SN is a mechanical keyless deadbolt lock designed for narrow stile door applications. It operates without batteries or electronics — the combination is entered directly on the pushbutton mechanism, which drives a deadbolt throw. No keys are required, and there are no electronic components to fail or replace. The satin nickel finish suits both interior and exterior installations. At 4.1 pounds, the unit is solidly built for commercial-grade use. Licensed locksmiths, door hardware installers, and general contractors are the typical trades for this product.
The 2900SN is suited for narrow stile aluminum or glass-frame doors commonly found in commercial storefronts, office entryways, and light industrial facilities. Its mechanical pushbutton design makes it a practical choice for applications where keyless access is required but power or network infrastructure is unavailable or impractical. It is sold as a single unit and is appropriate for both new installation and retrofit projects on compatible narrow stile door preparations.
Designed as an OEM-style replacement or new-installation deadbolt for narrow stile door assemblies. Verify door stile width and existing bore preparation before ordering.
Installation is typically performed by a licensed locksmith or a qualified door hardware installer. Confirm the door stile width and backset dimension match the 2900SN specifications before beginning work. Disengage any existing latch or lock hardware and follow the manufacturer instructions for spindle alignment and trim mounting. Local building and fire codes may govern keyless lock use on egress doors — verify compliance before installation.
