Product Overview

This high-quality Original Main Switch Keyless Ignition Barrel Key is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2024) models.

The main switch keyless ignition barrel key is the central switching unit that controls power to the motorcycle's electrical systems and engine start, using keyless smart key recognition to lock, unlock, and activate the ignition without a traditional key. Over time, internal contacts can wear or the smart key recognition module can degrade, causing unreliable starts, intermittent power loss, or complete failure of the keyless system. This original replacement restores full keyless ignition functionality, bringing back the convenience and security of the original system to your NMAX 125.
