The LiftMaster K41-0219-000 postal lock switch kit is a service replacement part used in select LiftMaster Smart Video Intercom access systems. Postal lock switch assemblies allow authorized postal access through a controlled entry point when the site is configured for that function. This kit is most commonly listed for the CAPXM medium video intercom and the CAPXLV / CAPXLV2 large video intercom series. It is not a universal key switch for every LiftMaster access control panel, and it should not be selected only by appearance. The correct part depends on the intercom model generation, cabinet, wiring harness, postal lock provision, and the replacement parts diagram for the specific panel.
A postal lock switch should be replaced without bypassing the access control system or leaving the entrance unsecured. If the switch wiring, relay behavior, or postal access requirement is unclear, have a qualified access control technician inspect the panel.
K41-0219-000 is commonly associated with CAPXM, CAPXLV, and CAPXLV2 Smart Video Intercom systems. Always verify the exact parts diagram for the panel before ordering.
No. K41-0219-000 is the postal lock switch kit. K41-0215-000 is commonly listed as a separate cam lock and kit for certain CAPXLV2 parts diagrams.
Do not assume CAPXS compatibility. This kit is commonly associated with medium and large LiftMaster Smart Video Intercom models, not the small CAPXS, unless the specific parts diagram says otherwise.
