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.
What we set out to build
-
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.
