摘要

A backup key for a vehicle includes a blade extending along an axis within a first plane and a head, attached to the blade, extending along the axis and defining a slot along the axis for insertion of a torque assisting device. The slot may be configured to receive a coin. The slot may be configured such that the torque assisting device, when inserted into the slot, lies in a second plane that is generally perpendicular to the first plane. A case for a portable electronic device includes a housing configured to receive the portable electronic device and defining a plurality of receptacles for one or more backup keys. The case also includes a key fob circuit for wirelessly interfacing with a keyless entry system and a communication circuit that connects to the key fob circuit for coupling the portable electronic device and the keyless entry system.
