Abstract

A method of monitoring a storage area within a lock box including: detecting, using at least one of: a load cell sensor or an object shape detection sensor, a physical property of a property access tool within the storage area prior to a showing of a property, the physical property of the property access tool including at least one of a weight of the property access tool or a shape of the property access tool; saving the physical property of the property access tool; detecting an end of the showing of the property; detecting, after the end of the showing, that the property access tool is not present in the storage area; and activating, using a controller, an alert in response to detecting that the property access tool is not present in the storage area.

Claims (45)

1. A method of monitoring a storage area within a lock box, the method comprising:

detecting, a weight of a property access tool within the storage area and detecting a shape of the property access tool within the storage area prior to a showing of a property;

saving the weight and the shape of the property access tool;

detecting an end of the showing of the property;

detecting, after the end of the showing, that the property access tool is not present in the storage area by detecting at least one of a weight or a shape of an object present in the storage area; and

activating, using a controller, an alert in response to detecting that the property access tool is not present in the storage area.

2. The method of claim 1 , wherein the detecting that the property access tool is not present in the storage area is completed by detecting at least one of (i) the weight of the object present in the storage area does not match the saved weight of the property access tool or (ii) the shape of the object present in the storage area does not match the saved shape of the property access tool.

3. The method of claim 1 , further comprising:

transmitting, using the controller, the alert to a mobile computing device.

4. The method of claim 3 , further comprising:

displaying a visual notification on the mobile computing device indicating that the property access tool has not been placed in the storage area.

5. The method of claim 3 , further comprising:

displaying a visual notification on the mobile computing device indicating that an incorrect property access tool has been placed in the storage area.

6. The method of claim 1 , wherein the property access tool is either a key or an access card.

7. The method of claim 1 , wherein at least one of the weight or the shape of the object present in the storage area does not match the saved weight or shape of the property access tool when the property access tool is not present in the storage area.

8. The method of claim 1 , wherein the alert is activated by the controller when the weight of the object present in the storage area does not match the saved weight of the property access tool, but the shape of the object present in the storage area matches the saved shape of the property access tool.

9. The method of claim 1 , wherein the alert is activated by the controller when the shape of the object present in the storage area does not match the saved shape of the property access tool, but the weight of the object present in the storage area matches the saved weight of the property access tool.

10. A lock box comprising:

a storage area configured to fit a property access tool therein;

a load cell sensor configured to detect a weight of the property access tool within the storage area and an object shape detection sensor configured to detect a shape of the property access tool within the storage area;

a controller comprising:

a processor; and

a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:

detecting the weight of a property access tool within the storage area and detecting the shape of the property access tool within the storage area prior to a showing of a property;

saving the weight and shape of the property access tool;

detecting an end of the showing of the property;

detecting, after the end of the showing, that the property access tool is not present in the storage area by detecting at least one of a weight or a shape of an object present in the storage area; and

activating an alert in response to detecting that the property access tool is not present in the storage area.

11. The lock box of claim 10 , wherein the detecting that the property access tool is not present in the storage area is completed by detecting at least one of (i) the weight of the object present in the storage area does not match the saved weight of the property access tool or (ii) the shape of the object present in the storage area does not match the saved shape of the property access tool.

12. The lock box of claim 10 , wherein the operations further comprise:

transmitting, using the controller, the alert to a mobile computing device.

13. The lock box of claim 12 , wherein the operations further comprise:

displaying a visual notification on the mobile computing device indicating that the property access tool has not been placed in the storage area.

14. The lock box of claim 12 , wherein the operations further comprise:

displaying a visual notification on the mobile computing device indicating that an incorrect property access tool has been placed in the storage area.

15. The lock box of claim 10 , wherein the property access tool is either a key or an access card.

16. The lock box of claim 10 , wherein at least one of the weight or the shape of the object present in the storage area does not match the saved weight or shape of the property access tool when the property access tool is not present in the storage area.

17. The lock box of claim 10 , wherein the alert is activated by the controller when the weight of the object present in the storage area does not match the saved weight of the property access tool, but the shape of the object present in the storage area matches the saved shape of the property access tool.

18. The lock box of claim 10 , wherein the alert is activated by the controller when the shape of the object present in the storage area does not match the saved shape of the property access tool, but the weight of the object present in the storage area matches the saved weight of the property.

19. A method of monitoring a storage area within a lock box, the method comprising:

detecting a shape of a property access tool within the storage area prior to a showing of a property;

saving the shape of the property access tool;

detecting an end of the showing of the property;

detecting, after the end of the showing, that the property access tool is not present in the storage area by detecting a shape of an object present in the storage area; and

activating, using a controller, an alert in response to detecting that the property access tool is not present in the storage area.
