First Claim
1. A multi layer data link communication system for after market installation on a vehicle having an existing remote starter/alarm system, an existing vehicle data bus, an existing vehicle computer and an existing OEM security interface, comprising:
- a multi-functional data bus interface module having a central processing unit (CPU), said multi-functional data bus interface module being located outside from and externally connected to and in data communication with the existing remote starter/alarm system for sending control commands to the vehicle computer, said control commands comprising commands to start an engine of the vehicle, said multi-functional data bus interface module being aftermarket installed in the vehicle; and
a transponder bypass module having a central processing unit (CPU), said transponder bypass module in communication with the OEM security interface and the multifunctional data bus interface module for transmitting and receiving authorization commands from the OEM security interface, said multi-functional data bus interface being aftermarket installed in the vehicle, wherein the transponder bypass module is connected to and in data communication with the multifunctional data bus interface module via a customized network protocol link or a data antenna communication protocol link, wherein the transponder bypass module allows the vehicle to start without using an OEM key associated with the existing remote starter/alarm system.
