Liftmaster 041SLG-0054, LOCK AND KEY
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.

Technician Note
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.
Before Ordering
- Confirm the operator model and serial or generation when available.
- Compare the original part number with the number listed on this product page.
- Review the operator parts diagram for the exact service part location.
- Check dimensions, mounting style, connector style, chain size, or finish where applicable.
- Do not substitute similar-looking parts unless the parts diagram confirms the match.
Professional Advisory
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.
Product Questions & Answers
What is the 041SLG-0054 used for?
It replaces the lock and key assembly on select LiftMaster slide gate operator covers or housings.
Does this fit the SLY300, SLY500, and SLY1000?
Some listings associate it with SLY300, SLY500, and SLY1000 slide operators, but the cabinet parts diagram should still be checked.
Is this a telephone entry system lock?
No. This row should be treated as a slide gate operator lock kit, not a CAPXL, EL, or IPAC entry-system lock.
When should the lock be replaced?
Replace it when keys are lost, the cylinder is seized, the cam is damaged, or the operator cover cannot be secured.
Can two LiftMaster locks that look similar be interchanged?
Not always. Cam length, cylinder size, mounting clip, and cover thickness can vary by cabinet.
