LiftMaster Q084 Cam Lock with Keys — Documented Legacy Elite Operator Applications

The LiftMaster Q084 is the cam-lock-with-keys offer associated with the emergency-key-release reference in documented legacy Elite operator parts information. It is a lock-related service item, not a complete actuator, release linkage or access-control receiver. Match the original lock, cam arrangement and operator drawing before ordering. Legacy CSW200UL documentation identifies Q084 separately from Q118 access-door keys, so the two references should not be treated as equivalent simply because both relate to keyed access on the same equipment.

Compatibility — Models, Versions and Exclusions

Identify the Lock Function and Inspect Its Mounting

Photograph the lock from both accessible sides and identify what its cam operates or retains. A similar key opening does not prove matching cylinder length, cam reach or attachment. If a previous repair changed the lock, the original equipment parts list may no longer describe the installed hardware. Have the technician compare the current assembly before selecting a replacement.

A lock that will not turn may be affected by a damaged cylinder, a bent cam or pressure from a misaligned cover or mechanism. Inspect those conditions before forcing the key or replacing only one piece. After installation, the intended access or release function must operate correctly without leaving the enclosure unsecured or interfering with the operator’s moving parts.

Specifications and Product Identification

Before Ordering

• Record the operator model and locate Q084 in its parts information.
• Identify the actual lock function, cylinder and cam arrangement.
• Inspect the cover, mounting opening and related mechanism for damage.
• Confirm the current supplied lock hardware and number of keys.

Package Contents and Separate Requirements

The source identifies a cam lock with keys. Confirm the current package for the cam, retention pieces and key quantity; a specific count is not established by this listing. A complete operator cover, release lever, actuator, access receiver or set of unrelated enclosure keys is not promised as included. Select damaged surrounding hardware separately rather than assuming it accompanies the lock.

Safety Warnings — Read Before Installation or Service

• WARNING: Accessing an operator or operating a release can expose hazardous components or permit unexpected gate movement. Use qualified service personnel for lock replacement.
• Isolate applicable power before opening or working inside the equipment, and secure the gate if the lock is associated with a release function.
• Do not force the lock, bypass its retention function or leave a service enclosure unsecured after repair. Keep keys under authorized control.
• Verify the intended lock and release behavior, restore covers and complete the operator’s required safety checks before normal use.

Related Products and Important Differences

• LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
• LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.

Frequently Asked Questions

Is Q084 a keys-only offer?

The source describes a cam lock with keys; Q118 is a separately identified access-key reference.

Will it fit every LiftMaster lock opening?

No. Match the cylinder, cam and equipment-specific service reference.

Is a complete manual-release linkage included?

A complete linkage is not promised. Confirm the current lock package and other required repair parts.

Will replacing the lock correct a bent cover?

No. Cover alignment and damaged mounting points require separate repair.
