Our Story

StarterStopper started with a simple question: What protects a vehicle when the thief has the keys?

We saw how common key theft, key cloning, and modern “relay” methods had become — and how often factory security and add-ons don’t help once access is already compromised. We wanted a solution that stays effective in the real world: quiet, reliable, and built to work without apps, subscriptions, or tracking.

The gap in "factory security"

Most vehicles are protected until they aren’t: once the key is stolen, copied, or electronically abused, many systems are easy to defeat. We didn’t want louder alarms or another app. We wanted an additional layer of security that’s independent of phones, cloud services, and key fobs — and that doesn’t add daily hassle.

  • Real protection

    An extra security layer that meaningfully raises the effort and risk for thieves — even when keys are compromised.

  • Zero nonsense

    No hype, no gimmicks. Engineering choices driven by reliability and real outcomes.

  • Easy to live with

    No subscriptions, no accounts, no charging, no pairing. Install once. Use every day.

Design criteria (what we won’t compromise on)

Additional layer above factory security

StarterStopper is designed to add a practical layer on top of existing vehicle systems.

Works across many vehicles

Vehicle-agnostic design philosophy (model requirements and fitment still apply — always check compatibility).

Low daily friction

Security shouldn’t become a chore. The system is designed for normal daily use.

Discreet & independent

No visible fob, no “special tag on the keyring”, no reliance on apps or cloud services.

Installer-friendly

Designed to be installable by qualified workshops (and by experienced DIYers where appropriate), without requiring ongoing software updates.

Reliability first

Built to work consistently without ongoing maintenance, charging, or subscriptions.

Affordable for real drivers

Security that is accessible for families and small businesses — not just luxury vehicles.

Quiet security for people who depend on their vehicles

We build honest security hardware that protects your vehicle — not your data. If it doesn’t improve real-world outcomes, we don’t ship it.
