How Do Code Alarm Remote Starters Work?


Quick Answer

Code alarm remote starters work by switching a car's ignition system on when the device receives a signal from the accompanying remote transmitter, which is usually a key fob. The remote starter connects to the ignition switch, the ignition wire, the power wire, the brake wire and the starter wire. The starter also connects to the tachometer wire and the car's ground wire.

Once properly connected, pressing the remote sends out a signal that switches all these systems on, which starts the engine. In general, pressing a special button on a code alarm system twice in two seconds activates it. To visually confirm starting, the starter turns on or flashes the vehicle's parking lights, depending on system settings.

Code Alarm remote starters also have other functions aside from switching the engine on. These include the keyless entry function, which unlocks the vehicle's doors, a progressive car finder feature that helps a car owner locate the vehicle in a crowded parking lot, and a personal protection alarm that suspends the normal functions of the transmitter buttons. Some also feature programmed transmitter notification systems that help identify unauthorized transmitters that attempt to access vehicles. Some may also have valet mode functions to disable remote starting if desired.

Optional features include a trunk release function that opens the trunk of the vehicle and a two-stage door unlock that unlocks the driver's door before opening the other doors.
