Remote keyless entry relay module and system.

A system and in-vehicle communication module for relaying a remote keyless entry command from a cellular network to a vehicle keyless entry receiver. The module include a cellular network receiver configured to receive a remote keyless entry command from a cellular network; and a keyless entry transmitter located in the vehicle and in communication with the cellular network receiver. The keyless entry transmitter is configured to transmit a remote keyless entry signal to a vehicle keyless entry receiver in the vehicle in order to execute a vehicle operation. By sending a remote keyless entry signal to a vehicle remote keyless entry system, installation and engineering costs can be reduced.
