Multiquip KEYISUZUF Starter Switch Key

The Multiquip KEYISUZUF Starter Switch Key is a genuine OEM replacement designed for DCA-series ultra-silent diesel generators, including the DCA25SSI, DCA25SSI2, DCA25SSAI, DCA25SSIU-GEER, DCA40SSI, DCA40SSAI, DCA45SSIU2, DCA45SSIU2-FEMA, DCA60SSI2, and DCA60SSAI. As a direct Multiquip OEM component, the part is manufactured to the exact specification of the original part, ensuring correct operation of the ignition and starter switch circuit. Sourced and sold by DHS Equipment, this key ships as a factory-genuine replacement for verified fitment across the DCA ultra-silent generator lineup.

Key Features

• Genuine OEM Ignition Integrity — Manufactured to the original switch specification, ensuring the key engages and releases the starter circuit with the correct detent positions and switch travel.
• Direct Drop-In Replacement — Matches the OEM key profile and switch cylinder of the DCA-series control panel, allowing straightforward swap without modification.
• Broad DCA Generator Fitment — Compatible across the DCA25SSI, DCA25SSI2, DCA25SSAI, DCA40SSI, DCA40SSAI, DCA45SSIU2, DCA60SSI2, DCA60SSAI, and related variants.
• Uninterrupted Start/Stop Control — A worn or missing starter key prevents the generator from starting or safely shutting down; replacing it restores full operator control of the machine.
• Electrical Safety Compliance — The ignition key is a primary electrical interlock on the generator; using the correct OEM key maintains the integrity of that interlock and avoids unintended circuit energization.

The starter switch key is the operator's direct interface with the generator's ignition circuit. Turning the key cycles the switch through its off, run, and start positions, controlling power to the control panel and engaging the starter motor. A worn, damaged, or lost key can prevent the unit from starting at all, or in some cases leave the circuit in an indeterminate state that prevents safe shutdown. Replacing the KEYISUZUF with a genuine Multiquip OEM key restores proper switch engagement and keeps the ignition circuit operating exactly as designed.
