Abstract

A vehicle security system includes a transmitter that is alternatively permanently mounted in or selectively removable from the vehicle. The transmitter communicates with a security system controller associated with the vehicle so that the transmitter is only useable under selected, authorized conditions. The transmitter enables a vehicle owner to access and operate a plurality of remotely located systems or devices such as a garage door opener, a home security system or a pager system, for example.

Claims

1. A security system for use in a vehicle, comprising:

a transmitter having at least one selectively actuatable switch that generates a signal for communicating with at least one receiver that is located remotely from the vehicle, said transmitter having a housing that supports said switch;

a receptacle supported on the vehicle and having a portion that receives said transmitter housing so that said housing is selectively removable from the vehicle; and

a controller supported on the vehicle that communicates with said transmitter, said controller selectively enabling said transmitter to operate, wherein said transmitter includes an activation module having a code reading portion that determines whether an authorized activation code has been received from said controller, said activation module arranged to render said transmitter unusable until the authorization code has been received by said activation module.

2. The system of claim 1, wherein said receiver is associated with a device selected from the group of devices consisting of a garage door opener, a home security system, and a pager.

3. The system of claim 1, wherein communications between said transmitter and said receiver and said controller include rolling code encrypted signals.

4. The system of claim 1, wherein said authorized activation code enables said transmitter to be used after said housing has been removed from said receptacle subsequent to receiving said activation code.

5. The system of claim 1, wherein there are two said authorized activation codes, a first authorized code that enables said transmitter to be used only while said housing is received in said receptacle and a second authorized code that enables said transmitter to be used when said housing has been removed from said receptacle.

6. The system of claim 1, wherein said transmitter includes a first communication link that is supported by said housing and said controller includes a second communication link supported by the vehicle, said first communication link being coupled to said second communication link when said housing is received in said receptacle.

7. The system of claim 6, wherein said controller selectively enables said transmitter to be operable through said coupling of said first and second communication links.

8. The system of claim 1, wherein said transmitter includes a plurality of switches and there are a corresponding plurality of receivers located remotely from the vehicle and wherein said transmitter is useable to communicate with said receivers when said housing is received by said receptacle and when said housing is removed from the vehicle.

9. A security system for use in a vehicle, comprising:

a transmitter permanently mounted in the vehicle and having a plurality of switches that are useable to selectively generate communication signals for communication with a plurality of devices remote from the vehicle;

a controller supported by the vehicle and generating an authorized activation code; and

a security link supported by the vehicle and interconnecting the controller and the transmitter and wherein the controller supplies the authorized activation code to the transmitter via the security link such that the transmitter is only operational subsequent to receiving the activation code.

10. The system of claim 9, wherein the security link comprises a hard wire connection between the transmitter and the controller.

11. The system of claim 9, wherein the authorized activation code includes an encrypted rolling code signal.

12. The system of claim 9, wherein the plurality of devices that receive communication signals from the transmitter include a garage door opener device, a home security device and a local area pager device.

13. The system of claim 9, wherein the controller generates the authorized activation code only after a preselected condition is met.

14. The system of claim 9, wherein the transmitter remains operational after receiving the authorization code only under preselected conditions.

15. A method of controlling a security system that includes a transmitter supported in a vehicle that also includes an electronic controller, comprising the steps of:

(A) mounting the transmitter within the vehicle;

(B) determining whether a preselected condition exists; and

(C) enabling the transmitter to be used by a user by supplying an activation code from the electronic controller to the transmitter only after the condition of step (B) exists.

16. The method of claim 15, wherein step (A) includes permanently mounting the transmitter in the vehicle and wherein the method further includes providing a direct communication link between the transmitter and the controller on the vehicle.

17. The method of claim 15, wherein step (B) includes determining whether an authorized code has been received by one of a vehicle remote keyless entry device or an ignition switch supported in the vehicle.

18. The method of claim 15, further comprising the step of maintaining the transmitter in an enabled state subsequent to performing step (C) while at least one preselected operation condition exists and deactivating the transmitter when the preselected condition ceases to exist.
