The LiftMaster 041SLG-0054 is a lock and key service kit for select slide gate operator covers and housings. On a gate operator, the cabinet lock is more than a convenience item. It helps keep the control compartment, wiring, manual controls, and service components protected from tampering and weather exposure. Replacement is usually needed when the cylinder no longer turns, the cam is damaged, keys are missing, or the cover cannot be secured after service. This kit is commonly associated with LiftMaster slide gate operators and SLY-series references, but lock fitment depends on the cabinet design and access panel. Compare the lock body, key cylinder, cam orientation, and parts diagram before ordering.
Compatibility note: Use this part only when the installed operator manual, parts diagram, or original part number supports the match. Similar LiftMaster parts may not interchange by appearance alone.

Before replacing this part, inspect the surrounding hardware, mounting points, wiring where applicable, and any related drive or sensing components. A failed surrounding part can make a good replacement part appear defective after installation.
Gate operators can move heavy gates and may include high-voltage circuits, stored spring force, pinch points, and monitored safety devices. Mechanical repairs should be completed with the operator secured and power disconnected where required. Electrical testing, high-voltage work, and safety-device issues should be handled by a qualified gate technician.

Some listings associate it with SLY300, SLY500, and SLY1000 slide operators, but the cabinet parts diagram should still be checked.
No. This row should be treated as a slide gate operator lock kit, not a CAPXL, EL, or IPAC entry-system lock.
Replace it when keys are lost, the cylinder is seized, the cam is damaged, or the operator cover cannot be secured.
Not always. Cam length, cylinder size, mounting clip, and cover thickness can vary by cabinet.
