Abstract

A system for preventing the unauthorized by-pass of an OEM security system is disclosed. The system includes an OEM starter for starting a vehicle; an OEM security system in communication with said starter; a by-pass kit for by-passing said OEM security system and enabling remote car starting of the vehicle without placing the key in the ignition; a remote car starter device in communication with the by-pass kit for sending a signal to the by-pass kit to start the engine; and a remote car starter transmitter in wireless communication with the remote car starter device. The signal that is sent to said by-pass kit is data, so that the by-pass kit is adapted to by-pass the OEM security system only upon receipt of the data signal. The improvement can be brought to both transponder-based bypass kits and microprocessor-based bypass kits.

Claims

1. A system for preventing the unauthorized by-pass of an OEM security system, comprising:

an OEM starter for starting a vehicle;

an OEM security system in communication with said starter;

a by-pass kit for by-passing said OEM security system and enabling remote car starting of said vehicle without placing said key in said ignition;

a remote car starter device in communication with said by-pass kit for sending a signal to said by-pass kit to start said engine; and

a remote car starter transmitter in wireless communication with said remote car starter device;

wherein said signal is data that is sent to said by-pass kit is data, and wherein said by-pass kit is adapted to by-pass said OEM security system only upon receipt of said signal.

2. A system according to claim 1, wherein said remote car starter is in wireless communication with said by-pass kit.

3. A system according to claim 1, wherein said remote car starter is in communication with said by-pass kit through a cable.

4. A system according to claim 1, wherein said by-pass kit includes a transponder on board and is encased in metal.

5. A system for preventing the unauthorized by-pass of an OEM security system comprising:

an OEM starter;

an OEM security system in communication with said OEM starter, said OEM security system including a transponder for starting said engine upon receipt of an authorized signal;

a remote starter including a wireless transmitter, said remote starter being in communication with a conventional by-pass kit; and

an OEM transponder jammer for constantly jamming said transponder of said OEM security system when enabled,

wherein said transmitter is adapted to disable and enable said OEM transponder jammer, so that when said OEM transponder jammer is enabled, said vehicle cannot be started even with a correct signal being emitted to said OEM security system.
