What is an Interface Module, or Bypass? Why do I need it?

Most newer vehicles have a factory anti-theft system (not to be confused with a proper security system) in them. Sometimes these are referred to as “Chip Keys” or Transponder Keys. In order for a remote starter to start the car, an Interface Module or “By-Pass” is used so that when the Remote Start is activated the system will allow the vehicle to start. The important part is to ensure that the device used does not totally disable your vehicles anti-theft system! Interface Modules are also increasingly required to work with newer vehicles computers and start sequences, beyond the basic Power and Start wiring that was needed 30 years ago when we started doing remote car starters!
