Door Preparation and Installation Checklist

1. Confirm the correct cylindrical lock bore, cross-bore and backset for the factory 9KZ37 or special 9KZ47 version.
2. Identify the frame's S3 ANSI or STK strike and match the selected factory hardware rather than substituting plates by appearance.
3. Choose #14, #15 or #16 lever style and verify compatible door handing and lock trim.
4. Check the building's small-format interchangeable-core mechanical override requirements and confirm core and key inclusion before ordering.
5. Program authorized PIN users, test the mechanical keyed bypass, and verify interior egress and any listed fire-rating requirements.

Not included unless stated: A new complete door, access-control panel, replacement door frame, permanent SFIC core, additional keys or separate monitoring hardware.
