Key Features

• Genuine OEM Construction — Manufactured by Multiquip to the precise tolerances required for correct key engagement and ignition switch operation on this equipment.
• Direct-Fit Replacement — Engineered to drop into the existing ignition switch housing on EH340 and QP-40TA models without alteration to the switch or surrounding components.
• Verified Fitment — Confirmed compatibility with EH340 and QP-40TA series machines; always cross-reference your model code before purchase.
• Correct Key Profile — The cut pattern matches the OEM ignition cylinder exactly, ensuring smooth insertion, positive engagement, and reliable start/stop function every time the key is turned.
• Operational Safety — A properly fitting ignition key prevents unintended starting, supports correct switch wear, and ensures the machine can be shut down immediately when needed.

The ignition key is the operator's primary interface with the machine's start and stop circuit. It engages the tumblers inside the ignition switch cylinder to allow the electrical circuit to open or close, enabling the engine to crank, run, or shut off. A worn, damaged, or incorrect key can cause intermittent starting failures, difficulty shutting the engine down, or accelerated wear on the ignition cylinder itself — all of which can lead to unexpected downtime in the field.
