Abstract

A vehicle remote start control system is for a vehicle including a vehicle engine, an electrical system, and a transponder reader. The transponder reader may enable the vehicle engine based upon wirelessly reading an authorized code from a transponder carried by a user and placed proximate the transponder reader. The system may include a remote start transmitter and a remote start controller at the vehicle. The remote start controller may include a transponder code bypass transmitter electrically connected to the vehicle electrical system for wirelessly transmitting the authorized code to the transponder reader responsive to the remote start transmitter to enable the vehicle engine.
