Abstract

A key fob assembly includes a mechanical key, a key fob, a control in the key fob, Hall effect switches in the key fob, and magnets associated with the mechanical key. The mechanical key is configured to cooperate with a mechanical lock. The key fob is configured to selectively connect with the mechanical key. The control in the key fob is for transmitting wireless signals to a vehicle to actuate components on the vehicle. The Hall effect switches in the key fob are each in electrical communication with the control. At least one of the Hall effect switches changes an operating state based on detecting a positive magnetic field and at least one other Hall effect switch changes an operating state based on detecting a negative magnetic field. Respective poles of the magnets are disposed such that connection of the mechanical key with the key fob in a storage position aligns the poles of the magnets with respective Hall effect switches for changing the operating state of the respective Hall effect switches.
