The LiftMaster 02-406-3 Keys are an OEM set of three replacement keys cut to code 301 for the LiftMaster 02-406 lock cylinder used on many LiftMaster commercial door operator control stations, gate operator cabinets, and access control enclosures produced from 2015 to present. Intended for restoring authorized access to keyed functions, these keys operate the 02-406 cylinder found on select LiftMaster/Chamberlain commercial and industrial applications, including keyed Up-Stop-Down stations, lockout-enabled controls, and service panels. As a direct replacement part, they are designed specifically for cylinders keyed to #301 and are not universal.
Use is straightforward with no programming required—simply insert into a compatible 02-406 cylinder and turn to unlock or enable controls. To confirm fit, check your existing lock or documentation for the 02-406 designation and verify the key code #301 on the lock face or original key. Ideal for facilities maintenance and dealer service calls, these replacement keys help maintain secure, authorized operation of LiftMaster commercial door and gate systems while supporting residential/commercial service environments that rely on 2015–present LiftMaster hardware.
