Abstract

A system and method for controlling remotely controlled components of a plurality of vehicles in response to a short range common signal emitted by a transmitter that can operate the components only during specified time periods. A transmitter can be programmed to provide a relatively long range customer signal that can operate the components at any time. The system and method are operative on a mutually exclusive basis wherein the remotely controlled components only respond to the common signal or the customer signal.

Claims

1. A security system for a vehicle, comprising:

a programming device disposed apart from the vehicle that generates a first control signal; and

a transmitter disposed apart from the programming device that receives the first control signal, the transmitter including a control switch for entering a command;

an oscillator that transmits a second control signal based upon the command, and

a programmable encoder for programming the second control signal transmitted by the oscillator;

wherein the first control signal inhibits the oscillator from transmitting the second control signal beginning at a specified time period.

2. The security system of claim 1 wherein the specified time period corresponds to a time of day when access to the vehicle is denied.

3. The security system of claim 1 wherein the programming device is a computer.

4. The security system of claim 1 wherein the control switch is actuated with a button disposed on the transmitter.

5. The security system of claim 1 wherein the oscillator transmits an RF signal.

6. The security system of claim 5 wherein the oscillator is adjustable to select a transmission range for the RF signal.

7. The security system of claim 6 wherein the transmission range is between approximately four to six feet.
