Five things
before you buy.
Anything else, email contact@starterstopper.com — a real person reads it.
Will it work on my car?
Any vehicle that uses a physical key to start. Push-to-start cars need the One module.
What if I forget my code?
Hold the program button on the control unit for 30 seconds with the battery disconnected — the unit factory-resets. Set a new code; the car still starts normally.
Does it drain the battery?
About 0.6 mA when armed — roughly the same as your factory clock. Vehicles parked for 6+ weeks during testing did not flatten their battery.
Can a thief just find it and bypass it?
They have to find it (smaller than a deck of cards), recognise it, and short two specific terminals — by which point they've spent more time than they would picking another car.
Can I uninstall it later?
Yes. Pull the harness, reconnect the original wires (we ship butt connectors for exactly this), done. No permanent modifications.
