A brand new aftermarket two position ignition key switch supplied under RMSTATOR part number RM05013, built as a direct replacement for the original unit fitted to the Honda TRX 450, TRX450R and TRX450ER quads from 2004 to 2014. The ignition key switch carries the whole ignition circuit through a pair of small contacts, and on a hard-used sport quad those contacts eventually suffer from vibration, dirt and water ingress.
The symptoms of a tired switch are familiar: the engine cuts out over rough ground, the machine will not fire until the key is worked back and forth, or everything dies without warning and then comes back a minute later. This replacement is a plug-and-play direct fit with a four wire, single plug layout and a simple two position off and on action, and it is supplied with two keys and a connector so nothing has to be cut into the loom. Every switch is bench tested before dispatch.

Frequently Asked Questions
Will this fit without modification?
Yes. It is a plug-and-play direct replacement for the original Honda switch, with a single four wire plug and a supplied connector, so the loom does not need cutting or splicing. Check the number on your original switch against the cross reference above before ordering.
What is included?
One two position ignition key switch, two keys and a connector. Every item is tested before dispatch.
How do I know my old key switch has failed?
Disconnect the battery and check continuity across the switch terminals in both key positions. A sound switch makes a clean circuit in the on position and breaks it completely in the off position, and the reading stays steady when the barrel and wiring are moved. Flickering or intermittent continuity, or a barrel that binds, means the switch is worn out.
Is this the same switch for the TRX450R and the TRX450ER?
Yes. RMSTATOR list one part, RM05013, covering the TRX 450, TRX450R and TRX450ER across the 2004 to 2014 range, cross referenced to Honda part number 35100-HP1-003.
