Starter Kill Switches
A starter kill switch is a relay that stops the starter from working until it is released. Done well, it adds a layer that thieves do not expect. It is meant for a parked car. We install it safely and explain how it works.

A kill switch or starter interrupt is for a parked vehicle only. It is installed so it cannot cut a moving vehicle, and it should never be used while a vehicle is moving. Check your contracts and local rules, and ask an attorney if you are unsure.
