How Remote Start Systems Work
Remote start systems are more complex than they appear. They involve a combination of hardware and software working in harmony to safely and reliably start your engine from afar.
The Key Fob and Its Signal
The key fob acts as a transmitter, sending a radio frequency signal to the vehicle’s receiver. This signal contains a specific code that identifies your key fob as authorized to start the engine. To prevent unauthorized access, these codes are often encrypted and change with each use.
The Vehicle’s Receiver and Control Module
Inside the vehicle, a receiver picks up the signal from the key fob. This receiver is connected to a control module, which is essentially the brains of the remote start system. The control module verifies the signal’s authenticity and checks various safety parameters before initiating the start sequence.
Safety Interlocks and Security Measures
Safety is paramount in remote start systems. Before the engine can be started remotely, the control module checks several crucial conditions. These include:
- Transmission in Park: The system ensures that the vehicle is in Park (or Neutral for manual transmissions) to prevent unintended movement.
- Parking Brake Engaged: Some systems require the parking brake to be engaged as an additional safety measure.
- Hood Closed: Many systems prevent remote start if the hood is open, to avoid accidental injury during maintenance.
- Brake Pedal Not Depressed: The system will not allow remote start if the brake pedal is depressed, as this could indicate someone is inside the car.
These safety interlocks prevent the vehicle from starting unexpectedly and protect both the vehicle and its surroundings.
The Starting Sequence
Once all safety checks are passed, the control module activates the starter motor, just as if you were turning the key in the ignition. The engine starts and runs for a pre-programmed duration, typically 10 to 15 minutes. After this time, the engine will automatically shut off to conserve fuel and prevent idling for extended periods.
