US 9,460,571 B2 · Backup key for multiple backup key integration into a mobile device case

Abstract

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.

Dependent claims

A key for a vehicle comprising:

a blade extending along an axis within a first plane;
and
a head, attached to the blade, extending along the axis having a height in the first plane that is at most twenty percent greater than a height of the blade in the first plane to reduce key size and defining a slot having a length along the axis that is greater than a width perpendicular to the axis for insertion of a torque assisting device that, when inserted in the slot, lies in a second plane generally perpendicular to the first plane such that a force applied perpendicular to a surface of the torque assisting device that lies in the second plane creates a torque to rotate the key about the axis.
