Abstract

Detecting unauthorized access of a locked key container having a key for a vehicle or a premises. An indication is received at a sensor coupled to the key that the key container is being tampered with. A notification is sent in response to receiving the indication that the key container is being tampered with.

Claims (47)

1. A method for detecting unauthorized access of a locked key container, the method comprising:

locking a key to a key container;

receiving an indication at a sensor that the key container is being tampered with, wherein the sensor is coupled to the key inside the key container; and

sending a notification in response to receiving the indication that the key container is being tampered with;

wherein upon the key container being unlocked and opened and the key removed from the key container, the sensor reducing sensitivity level to avoid generating a false alarm.

2. The method of claim 1 wherein the key is to a particular vehicle and the key container is located on or near the particular vehicle, and wherein receiving an indication at a sensor that the key container is being tampered with comprises receiving an indication of motion at a motion sensor that the key container is being tampered with.

3. The method of claim 2 wherein the indication of motion comprises cutting of the key container.

4. The method of claim 2 wherein the indication of motion comprises cutting of a lock to the key container.

5. The method of claim 1 wherein sending a notification in response to receiving the indication that the key container is being tampered with comprises sending an alert to central service.

6. The method of claim 1 wherein sending a notification in response to receiving the indication that the key container is being tampered with comprises sending an alert to one or more of the following:

an owner of a vehicle;

a manager of a sales lot;

a sales associate of a sales lot;

a security guard; and

a police department.

7. The method of claim 1 further comprising, in response to receiving an indication at a sensor that the key container is being tampered with, transmitting video of the key container being tampered with.

8. The method of claim 7 further comprising determining a direction of a signal and orienting a video camera based on the direction of the signal.

9. The method of claim 7 further comprising determining a time-of-flight of a signal, thereby determining a distance to the key container being tampered with.

10. The method of claim 1 wherein sending a notification in response to receiving the indication that the key container is being tampered with comprises sending a video evidencing that the key container is being tampered with.

11. A system for detecting unauthorized access of a locked key container, the system comprising:

a key locked in a key container;

a sensor coupled to the key within the key container;

an indication at the sensor that the key container is being tampered with; and

a notification generated in response to receiving the indication that the key container is being tamped with;

wherein upon the key container being unlocked and opened and the key removed from the key container, the sensor reducing sensitivity level to avoid generating a false alarm.

12. The system of claim 11 wherein the key is to a particular vehicle and the key container is located on or near the particular vehicle.

13. The system of claim 11 wherein the sensor is a motion sensor receiving the indication that the key container is being tampered with.

14. The system of claim 11 further comprising a computing device receiving the notification and the computing system providing an alert to at least one of the following:

an owner of a vehicle;

a manager of a sales lot;

a sales associate of a sales lot;

a security guard; and

a police department.

15. The system of claim 11 further comprising a video of the key container being tampered with.

16. The system of claim 11 further comprising a video camera oriented based on a direction of a signal from the sensor and on a time-of-flight of the signal from the sensor.

17. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer processor to cause the computer processor to perform a method for detecting unauthorized access of a locked key container, comprising:

receiving an indication at a sensor that a key container is being tampered with, wherein the sensor is coupled to a key inside the key container; and

receiving a notification in response to the indication that the key container is being tampered with;

wherein upon the key container being unlocked and opened and the key removed from the key container, the sensor reducing sensitivity level to avoid generating a false alarm.

18. The computer program product of claim 17 wherein receiving an indication from a sensor that a key container is being tampered with comprises receiving an indication of motion from a motion sensor that the key container is being tampered with, and wherein in response to receiving the notification an alert is sent to one or more of the following:

an owner of a vehicle;

a manager of a sales lot;

a sales associate of a sales lot;

a security guard; and

a police department.

19. The computer program product of claim 17 wherein the method further comprises, in response to receiving an indication from a sensor that a key container is being tampered with, transmitting video of the key container being tampered with.

20. The computer program product of claim 17 wherein the method further comprises determining a direction of a signal from the sensor in order to orient a video camera based on the direction of the signal and determining a time-of-flight of the signal from the sensor, thereby determining a distance to the key container being tampered with.
