Key Features
- Genuine OEM Construction — Manufactured by Husqvarna to original specifications, with precise key-profile tolerancing that matches the ignition switch cylinder exactly — no filing, bending, or guesswork.
- Broad Cross-Equipment Compatibility — A single part that spans CRT48 and CRT48PS power trowels and the full FS-series floor saw lineup, including FS3500G, FS4600G, FS5000D, FS7000D, FS7000DL, and FS7000DMT.
- Correct Ignition Engagement — The key profile is cut to activate the switch cleanly through all positions — Off, Run, and Start — preventing false starts, failed cranking, or ignition switch wear caused by an ill-fitting key.
- Drop-In Replacement — Slots directly into the OEM ignition switch with no modification, restoring full machine start-up function immediately.
- Operator Safety Compliance — Using the correct keyed ignition ensures the machine's start and stop circuit functions as designed, an important safeguard on heavy floor saws and ride-on trowels operated in occupied work areas.
The ignition key is the physical interface between the operator and the machine's electrical start circuit. When inserted and turned, it rotates the ignition switch cylinder through Off, Run, and Start positions, completing the circuits that allow the engine to crank and run. A worn, damaged, or incorrect key can cause intermittent starting, unintended shutdowns, or accelerated wear on the switch cylinder itself — any of which can halt production on a floor saw mid-cut or delay a troweling pass. Replacing a damaged key with the correct OEM part restores reliable, consistent ignition control across every shift.
