Abstract

A remote access system remotely accesses one or more electronic locks from a locally placed computer. The computer includes a key receptacle electrically coupled to the computer. The key receptacle allows ingress of a key, whereupon insertion of the key and login permission granted allows access of the computer to an electronic lock via a communication channel. The electronic lock is mechanically, electrically and functionally connected to activate and deactivate a locking mechanism of a lockable device. According to one arrangement, the computer is connected to the electronic lock via the communication channel to allow the user remote login to the electronic lock. The user located remote from the lock may therefore operate the lock from the remote location.

Claims

1. A remote access system, comprising:

a computer;

a key receptacle electrically coupled to said computer wherein said key receptacle is adapted to receive a key for conveying user information to said computer indicative of a user to which said key is issued;

an electronic lock located separate and distal from said computer, said electronic lock includes a storage device for storing a set of operating parameters, and said electronic lock further includes a programmable unit for activating and deactivating a locking mechanism functionally connected to the programmable unit; and

a communication channel coupled between said computer and said electronic lock for transmitting the user information from said computer to said electronic lock, wherein said communication channel bypasses said key receptacle, and wherein said electronic lock, in response to said user information from said computer, is configured to allow said user to read a lock database stored within said electronic lock from said computer, said user information identifying said user to said electronic lock.

2. The remote access system as recited in claim 1 wherein said user information includes a set of permissions, and wherein said electronic lock is configured to allow user control of said electronic lock according to the set of permissions.

3. The remote access system as recited in claim 2 wherein the set of permissions includes a remote access permission of an electronic lock.

4. The remote access system as recited in claim 3 wherein said electronic lock is configured to deny login if the remote access permission is not given.

5. The remote access system as recited in claim 1 wherein said electronic lock is configured to request a PIN code prior to logging in said user.

6. The remote access system as recited in claim 1 wherein said programmable unit is configured to enter a diagnostic mode.

7. The remote access system as recited in claim 6 wherein said electronic lock is configured to login said user during a time period in which said programmable unit is in said diagnostic mode.

8. The remote access system as recited in claim 7 wherein said programmable unit is configured to enroll said key inserted into said key receptacle such that said key is enabled to login to said electronic lock.

9. The remote access system as recited in claim 1 wherein said communication channel comprises an RS-232 cable.

10. The remote access system as recited in claim 1 wherein said communication channel comprises a pair of modems operably connected to a telephone line.

11. The remote access system as recited in claim 10 wherein a first of said pair of modems is coupled to said computer.

12. The remote access system as recited in claim 10 wherein a second of said pair of modems is coupled to said electronic lock.

13. The remote access system as recited in claim 12 wherein said second of said pair of modems is maintained, during use, in an auto-answer mode.

14. The remote access system as recited in claim 1, wherein said electronic lock is further configured to allow said user to manipulate said set of operating parameters stored within said lock from said computer.
