Abstract

A remotely actuated door lock is provided. The remotely actuated lock includes a transceiver for establishing telephone communication with a remote telephone and for receiving a transmitted identification code therefrom. The door lock includes a microprocessor, a programmable logic controller or the like for comparing the transmitted identification code with a stored identification code stored in memory associated with the processor or controller. The door lock further includes a lock bolt actuator in communication with a lock bolt for changing a state of the door lock. The lock bolt actuator is selectively actuated if the transmitted identification code matches the stored identification code. However, if the transmitted identification code does not match the stored identification code, then the transceiver transmits a first alert message to a user, alerting the user to possible unauthorized access.

Claims

1. A method of remotely actuating a door lock, consisting the steps of:

establishing telephone communication with a door lock actuating mechanism by dialing a telephone number associated with the door lock;

transmitting an identification code to the door lock actuating mechanism;

comparing the transmitted identification code with an authorization code stored in the door lock actuating mechanism;

activating the door lock actuating mechanism to change a state of the door lock when the transmitted identification code matches the stored authorization code;

transmitting a first alert message without changing the state of the door lock when the

transmitted identification code does not match the stored authorization code;

monitoring the door lock continuously;

detecting unauthorized access to the door lock, and

transmitting a secondary alert message to a user specified address when unauthorized access is detected;

wherein the step of transmitting the first alert message and the step of

transmitting the second alert message each consists of transmitting a text message

to a user-specified address.

2. The method of remotely actuating a door lock as recited in claim 1, wherein the step of transmitting the identification code to the door lock comprises transmitting a personal identification number to the door lock actuating mechanism.

3. The method of remotely actuating a door lock as recited in claim 1, wherein the step of activating the door lock actuating mechanism comprises the steps of:

locking the door lock when an initial state of the door lock is an unlocked state; and

unlocking the door lock when the initial state of the door lock is a locked state.

4. A remotely actuated door lock, comprising:

a door lock;

a door lock actuating mechanism connected to the door lock;

a transceiver; and

a controller connected to the door lock actuating mechanism and the transceiver, the controller having;

memory;

means for comparing an identification code received by the transceiver with an authorization code stored in the memory;

means for generating a first alert when the received identification code is not the same as the authorization code;

a sensor configured to continuously monitor the door lock and to generate a signal to said controller when the sensor detects tampering with the door lock;

means for generating a second alert when a signal is received from the sensor signifying tampering with the door lock;

wherein the first alert message and the second alert message each consists of a text message transmitted to a user-specified address; and

means for activating the door lock actuating mechanism to toggle the door lock between a locked state and an unlocked state when the received identification code is the same as the authorization code stored in the memory.

5. The remotely actuated door lock as recited in claim 4, wherein the authorization code comprises a personal identification number.

6. The remotely actuated door lock as recited in claim 4, wherein the first alert

comprises a text message, said controller further comprising means for activating

the transceiver to transmit the text message to a user-specified address

programmed into said memory.

7. The remotely actuated door lock as recited in claim 4, wherein the second alert comprises a text message, said controller further comprising means for activating the transceiver to transmit the text message to a user-specified address programmed into said memory.

8. A remotely actuated door lock, comprising:

a door lock;

a door lock actuating mechanism connected to the door lock;

a transceiver; and

a controller connected to the door lock actuating mechanism and the transceiver, the controller consisting of;

memory;

means for comparing an identification code received by the transceiver with an authorization code stored in the memory;

means for activating the door lock actuating mechanism to toggle the door lock between a locked state and an unlocked state when the received identification code is the same as the authorization code stored in the memory; and

a sensor configured to continuously monitor the door lock and to generate a signal to said controller when the sensor detects tampering with the door lock

wherein signal is selected from the group consisting of a first alert message and a second alert message, wherein each text message is transmitted to a user-specified address.

9. The remotely actuated door lock as recited in claim 8, wherein the authorization code comprises a personal identification number.

10. The remotely actuated door lock as recited in claim 8, wherein said controller generating a first alert when the received identification code is not the same as the authorization code.

11. The remotely actuated door lock as recited in claim 10, wherein the first alert comprises a text message, said controller being coupled for activating the transceiver to transmit the text message to a user-specified address programmed into said memory.

12. The remotely actuated door lock as recited in claim 8, wherein said controller generating a second alert when a signal is received from said sensor signifying tampering with the door lock.

13. The remotely actuated door lock as recited in claim 12, wherein the second alert comprises a text message, said controller being coupled for activating the transceiver to transmit the text message to a user-specified address programmed into said memory.
