Lock Key
The safety key acts as a physical bridge for the high-current DC circuit. Over time, the plastic retaining tabs can wear down or the internal contact points can become pitted, preventing the mower from sensing that the safety bridge is closed. Replacing the key restores the mechanical integrity of the primary safety interlock.

Switch Unit
This microswitch is actuated by the handle bail lever and is responsible for signaling the controller to energize the motor. Mechanical fatigue in the internal leaf spring or moisture ingress can cause the switch to fail in the 'open' position. A new switch unit ensures the 'deadman' functionality correctly communicates with the electronic control unit.
