Abstract

A security system and method for an in-vehicle remote transmitter that transmits a wireless control signal and has an activation button. A controller determines whether a vehicle status is authorized and permits transmission of the wireless control signal by the in-vehicle remote transmitter if the vehicle status determined is authorized.

Claims

1. A security system for an in-vehicle remote transmitter, the transmitter for transmitting a wireless control signal and having an activation button, the system comprising:

a controller for determining, in response to an input signal representing actuation of the activation button by an operator, whether a vehicle status is authorized;

wherein the controller permits transmission of the wireless control signal by the in-vehicle remote transmitter if the vehicle status determined is authorized.

2. The system of claim 1 wherein the controller determines whether the vehicle status is authorized based on a vehicle immobilization system signal.

3. The system of claim 1 wherein the controller determines whether the vehicle status is authorized based on a vehicle remote entry system signal.

4. The system of claim 1 wherein the controller determines whether the vehicle status is authorized based on a presence of a key in a vehicle lock cylinder.

5. The system of claim 4 wherein power is provided to the in-vehicle remote transmitter based on the presence of the key in the vehicle lock cylinder.

6. The system of claim 1 wherein the in-vehicle remote transmitter further comprises a plurality of buttons and the controller determines whether the vehicle status is authorized based on a pattern of actuation of at least one of the plurality of buttons.

7. The system of claim 1 wherein the in-vehicle remote transmitter further comprises a receiver for receiving a wireless signal, and the controller determines whether the vehicle status is authorized based on the wireless signal.

8. A security system for an in-vehicle remote transmitter, the transmitter for transmitting a wireless control signal, the system comprising:

a controller for determining whether a vehicle status is authorized;

wherein the controller enables the in-vehicle remote transmitter for transmission of the wireless control signal if the vehicle status is authorized.

9. The system of claim 8 wherein the controller determines whether the vehicle status is authorized based on a vehicle immobilization system signal.

10. The system of claim 8 wherein the controller determines whether the vehicle status is authorized based on a vehicle remote entry system signal.

11. The system of claim 8 wherein the controller determines whether the vehicle status is authorized based on a presence of a key in a vehicle lock cylinder.

12. The system of claim 11 wherein power is provided to the in-vehicle garage door opener remote transmitter based on the presence of the key in the vehicle lock cylinder.

13. The system of claim 8 wherein the in-vehicle remote transmitter further comprises a plurality of buttons and the controller determines whether the vehicle status is authorized based on a pattern of actuation of at least one of the plurality of buttons.

14. The system of claim 8 wherein the in-vehicle remote transmitter further comprises a receiver for receiving a wireless signal, and the controller determines whether the vehicle status is authorized based on the wireless signal.

15. A security method for an in-vehicle remote transmitter, the transmitter for transmitting a wireless control signal and having an activation button, the method comprising:

receiving an input signal representing actuation of the activation button by an operator;

determining whether a vehicle status is authorized; and

transmitting the wireless control signal if the vehicle status determined is authorized.

16. The method of claim 15 wherein determining whether the vehicle status is authorized is based on a vehicle immobilization system signal.

17. The method of claim 15 wherein determining whether the vehicle status is authorized is based on a vehicle remote entry system signal.

18. The method of claim 15 wherein determining whether the vehicle status is authorized is based on a presence of a key in a vehicle lock cylinder.

19. The method of claim 15 wherein the in-vehicle remote transmitter further comprises a plurality of buttons and determining whether the vehicle status is authorized is based on a pattern of actuation of at least one of the plurality of buttons.

20. The method of claim 15 wherein the in-vehicle remote transmitter further comprises a receiver for receiving a wireless signal, and determining whether the vehicle status is authorized is based on the wireless signal.
