Abstract

A vehicle key testing device includes a housing, an antenna, and an electrical input. The housing defines an interior space and is configured to have a vehicle key positioned into the interior space. The antenna is mounted in the interior space. The electrical input is configured to activate at least one wireless aspect of the vehicle key.

Claims

1. A vehicle key testing device comprising:

a housing defining an interior space and configured to have a vehicle key positioned into the interior space;

an antenna mounted in the interior space; and

an electrical input configured to activate at least one wireless aspect of the vehicle key.

2. The vehicle key testing device according to claim 1, wherein

the antenna is configured to simulate a corresponding antenna on a vehicle.

3. The vehicle key testing device according to claim 1, further comprising

a low frequency switch connected to the antenna.

4. The vehicle key testing device according to claim 1, wherein

the electrical input is a control circuit connected to the low frequency switch and configured to connect to the vehicle key.

5. The vehicle key testing device according to claim 4, wherein

the control circuit is configured to connect to a control system to control the vehicle key.

6. The vehicle key testing device according to claim 4, wherein

the control circuit is configured to simulate a voltage of a battery of the vehicle key.

7. The vehicle key testing device according to claim 4, wherein

the control circuit is configured to control the at least one wireless aspect of the vehicle key.

8. The vehicle key testing device according to claim 4, wherein

the antenna is a first antenna of a plurality of antennas and the control circuit is configured to selectively activate one of the first antenna and a second antenna of the plurality of antennas.

9. The vehicle key testing device according to claim 1, wherein

the housing is configured to prevent signals from the vehicle key from passing through walls thereof.

10. The vehicle key testing device according to claim 1, wherein

the housing is aluminum.

11. A method of testing a vehicle key, comprising:

placing a vehicle key inside a housing of a key testing device;

coupling the vehicle key to a control circuit;

instructing the control circuit to activate at least one wireless aspect of the vehicle key;

receiving a signal from the vehicle with an antenna disposed inside the housing; and

transmitting the signal to a control module.

12. The method according to claim 11, wherein

the antenna simulates a corresponding antenna on a vehicle.

13. The method according to claim 11, wherein

the transmitting the signal to a control module including transmitting the signal through a low frequency switch connected to the antenna.

14. The method according to claim 11, further comprising

connecting the control circuit to a control system, and controlling the vehicle key via the control system.

15. The method according to claim 14, further comprising

simulating a voltage of a battery of the vehicle key.

16. The method according to claim 14, wherein

the antenna is a first antenna of a plurality of antennas, and selectively activating, via the control circuit, one of the first antenna and a second antenna of the plurality of antennas.

17. The method according to claim 11, further comprising

preventing signals from the vehicle key from passing through walls of the housing.

18. The method according to claim 11, wherein

the housing is aluminum.
