1. An access system comprising:
- a computer for communicating over a primary wireless communication path;
a lock including a lock circuit for communicating over a secondary wireless communication path, and for energizing a lock mechanism to unlock the lock based upon instructions received over the secondary wireless communication path; and
a key including a key circuit for communicating with the computer over the primary wireless communication path, for communicating with the lock over the secondary wireless communication path, and for inductively coupling energy from the key to the lock to provide power to the lock circuit;
wherein the key is authorized to unlock the lock absent a de-authorizing instruction from the computer and absent a determination that the key has not been in contact with the computer over the primary wireless communication path for a predetermined time amount during a predetermined period of time.

11. An access system comprising a plurality of locks, a plurality of keys, and a computer disposed at a remote location from the keys and locks, wherein:
-
each lock is configured to receive instructions from the keys and to energize a lock mechanism to unlock the lock; the computer is configured to communicate with the keys over a primary wireless communication path to receive usage data from the keys and to send de-authorization instructions to the keys; and each key is configured to communicate over the primary wireless communication path with the computer, communicate with the locks over a secondary wireless path, and to supply inductively coupled energy to at least partially energize or recharge a lock with which the key is communicating; wherein each key is authorized to unlock one of the locks absent a de-authorizing instruction received over the primary wireless communications path from the computer and absent a determination that the key has not been in contact with the computer over the primary wireless communication path for a predetermined time amount during a predetermined period of time. - View Dependent Claims (12, 13, 14)
