The LOCKEY 3835OIL is a mechanical keyless lever lock with a built-in passage function and a single combination entry code. Designed for door security without the need for batteries or electronics, this lock operates entirely through a mechanical pushbutton mechanism. The oil rubbed bronze finish provides a durable, corrosion-resistant appearance suited to both interior and exterior door applications. Locksmiths, security contractors, and facility maintenance professionals install this type of hardware on residential and light commercial doors where reliable keyless access control is required without dependence on power or network infrastructure.
This lock is appropriate for residential entryways, office doors, utility rooms, and access-controlled interior passages where a single combination code is sufficient. The passage function allows free egress from the secured side without entering a code, making it suitable for doors where one-way code entry is the standard requirement. It ships as an individual unit and is available in case quantities of 10 for contractor or facilities applications.
Designed as an OEM-style replacement or new-installation mechanical keyless lever lock for standard residential and light commercial door preparations accepting lever lockset hardware.
Installation is typically performed by a licensed locksmith or qualified security hardware contractor. Verify that the door preparation and backset dimensions match the lock requirements before beginning installation. No electrical power or low-voltage wiring is required, but standard door hardware installation tools including a hole saw, chisel, and screwdrivers are needed. Review local building codes for egress and access control hardware requirements prior to installation.
