Abstract
A multi-function key system and method is provided that includes key identification system, a first key, and a second key. The multi-function key system is in communication with an item of power equipment, and comprises first and second sensors for detecting magnetic fields. The first key is configured to interact with the key identification system, the first key comprises a first magnet generating a first magnetic field. The second key is configured to interact with the key identification system. The second key comprises a second magnet generating a second magnetic field. Wherein the first and second sensors differentiate between the first and second key based upon the first and second magnetic fields. The key identification system initiates a first functionality of the power equipment responsive to identifying the first key, and initiates a second functionality of the power equipment responsive to identifying the second key.
