A CAN bus connection gives the system all the vehicle data it needs without extensive changes to the wiring. Your new car warranty stays.
02 — 360° protection
Doors, hood, trunk, cabin.
Perimeter protection, wireless PIR and magnetic sensors, and a tilt sensor against towing and wheel theft.
03 — Authorization
Unlocking isn't enough.
Keyless cars are stolen by relaying the key signal. KEETEC requires a second step — the app, a key fob or a secret PIN on the steering wheel.

KEETEC Car Security
Car security
CAN bus alarms, immobilisers and GPS trackers, developed in Slovakia and proven in practice together with installers.
Choose how you prove you're the owner. Without authorization the engine won't start — not even with the original key in hand. Try all three.
A sequence of factory steering-wheel button presses is your secret code. Without it the car stays immobilized, even if a thief unlocks it with a copied key signal.
