This is a genuine replacement ignition key that is manufactured by MTD for use in select models of outdoor power equipment. The ignition key is a plastic piece that is inserted into the ignition cylinder to start the machine. Turning the plastic key will signal to the engine to fire. This is a durable plastic piece, but it can become damaged or lost over time, which will render the machine unable to start. Replacing it will be necessary in order to operate the unit. This genuine OEM ignition key is manufactured to exact standards. It can be used in snowblowers and snow throwers from MTD, Yard Machines, Troy-Bilt, Cub Cadet, Yard-Man, and Husky. The durable plastic key is sold as an individual unit and does not require any tools for installation. This is a simple replacement that should only take a couple of minutes. In the event that the old key is damaged or stuck in the ignition, it may take more effort. It is important to disconnect the power supply for safety before performing any repairs, as well as to wear gloves for hand protection.
