What a Starter Kill Switch Does, and Does Not Do

Key takeaways

  • It prevents a parked car from starting until released
  • It is meant for parked cars, never for use while driving
  • It works best with an alarm and a tracker
  • Placement and wiring quality matter

A kill switch is a relay in the starter circuit. When it is open the starter will not turn.

What it does

It makes a quick theft much harder, because the car will not start.

What it does not do

It does not stop a tow truck, and a determined thief may find it. That is why we pair it with an alarm and a tracker.

Safe use

It is for a parked vehicle. We install it so it cannot cut a moving car.
