Most remote car starters can be divided into two primary categories – one-way and two-way. Many of the standard systems are typically of the one-way variety, which means the data from your transmitter is being sent to the vehicle in one direction. When a button is pressed on the remote, a signal is transmitted to the car, which will often acknowledge receipt of that signal by flashing the parking lights, generating an audible signal, or both. As long as you are within range, which may be many hundreds of feet, you can confirm that your vehicle has started.
