Multiquip 50404900 Starter Key

The Multiquip 50404900 Starter Key is a genuine OEM component designed for MVH308DZ, MVH408DZ, MVH508DZ, MVH308DE, MVH408DE, MVH508DE, and QP4TZ equipment. As an authentic Multiquip OEM part, it is manufactured to the same specification as the original, ensuring correct fit and function across all compatible models. This key is a direct replacement for the original ignition starter key on these machines, with no modification needed to the keyswitch assembly. Sourced directly through authorized Multiquip distribution channels, part number 50404900 is the correct replacement whenever the original key is lost, worn, or damaged.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specification, ensuring the correct key profile for proper ignition switch engagement without slipping or misfiring.
• Correct Key Profile — Cut and coded to match the ignition switch used across the MVH308DZ, MVH408DZ, MVH508DZ, MVH308DE, MVH408DE, MVH508DE, and QP4TZ, dropping in exactly as the original.
• Broad Fitment Across MVH and QP Series — Covers the MVH308, MVH408, and MVH508 reversible plate compactors in both DZ and DE configurations, plus the QP4TZ trash pump, making it a versatile stocking item for mixed fleets.
• Prevents Ignition System Damage — Using the correct key profile protects the ignition switch cylinder from wear caused by ill-fitting or improvised replacements, extending switch service life.
• Operational Safety — A properly fitting starter key ensures the ignition switch engages and disengages cleanly and completely — critical for reliable machine startup and safe shutdown on plate compactors and pumps.

The starter key is the operator's primary interface with the ignition switch, engaging the switch cylinder to power the machine on and allowing a clean shutoff when released or turned to the off position. On reversible plate compactors and trash pumps, a worn or incorrectly profiled key can cause intermittent starting failures, prevent full switch engagement, or make it impossible to shut the machine down reliably. Replacing a damaged or lost key with the correct OEM part — Multiquip 50404900 — restores proper ignition function and ensures the switch cylinder is not subjected to unnecessary stress from a mismatched profile.
