Available as an exit-only model and a GSA-approved FF-L-2890C Lock Type I & II Push/Pull version, the LKM10K aims to provide a secure access solution. Installation involves specific considerations for door thickness and may require optional standoff kits for hollow metal doors.

Lockmasters, Inc. provides a two-year limited warranty covering defects in materials and workmanship, contingent upon adherence to installation and operating instructions.
Device Overview and Models
The LockMasters LockOne LKM10K is presented as a second-generation pedestrian door lock. It is available in at least two configurations: an exit-only model and a GSA-approved version meeting FF-L-2890C standards, specifically Lock Type I & II – Push Pull. The GSA-approved model is also compatible with Security Door Controls (SDC) 920 Push Pull handles. The device is designed to change the way users think about security, according to promotional material included in the documentation.
Installation Procedures
Installation of the LKM10K requires careful attention to door thickness. The device is initially configured for 1-3/4” and 2” thick doors. If a door is thinner than these dimensions, the stand-offs must be cut to size. Lockmasters offers a stand-off kit for doors exceeding 2” in thickness, which is recommended for all hollow metal door installations.
The installation process involves marking the door for the exterior trim using a template. Establishing the high side of a beveled door is a critical step in this process. The documentation references Figure 2 for establishing the high side of a beveled door. The exterior trim mounting template is available as Part Number 10KERHTMP for right-hand doors and 10KELHTMP for left-hand doors. A QR code is provided for accessing a detailed video of the installation instructions.
Specific drilling procedures are outlined for metal doors. A 5/16” wood drill bit must be used for the raceway escutcheon on fire-rated doors. For metal doors, a 5/16” metal drill bit is used for the wire entry hole (F). A 3/8” drill bit is used to create the light indicator hole (E), drilling only through the outer skin of the metal door.
Key Override Feature
The LKM10K includes a key override feature. Users are instructed to refer to separate instructions before drilling for this feature. Lockmasters recommends using an Interchangeable Core rim cylinder to facilitate re-keying. The key override feature will not override a combination lock, but will override the access control system.
Components and Accessories
The LKM10K package includes several components. These include the base plate, fully assembled, and spindles with retaining alignment rings. The package also contains a base plate cover (parts A, B, and C) and a change key plug (D).
The device is compatible with several accessories, including:
- S&G 2740B Lock Shield
- Light Indicator Collar
- 1-3/4” & 2-5/8” Spindles

Additional Notes
The documentation references a version H of the installation instructions, dated October 2020. The documentation also includes a copyright notice for Lockmasters, Inc. 2020. An optional 1/8” Hex Wrench is listed as a tool needed for installation of the Key Override Feature.
