Apple has registered a new patent application, already codenamed the iKey.  The technology allows you to use an electronic device as an alternative to keys, for example, to unlock a front door, gain access to an office or car door.  The patent states: “The device can communicate with an external device to open a lock.”

Car manufacturers Toyota, Mercedes and Lexus have recently begun to introduce keyless access to vehicles via key fobs.

The technology used is known as Near Field Communication.
