Introduction – Why Keyless Cars Need Extra Protection
Modern keyless‑entry systems make life convenient, but they also expose your vehicle to relay attacks and key‑cloning. In 2024 alone, keyless theft rose by 22 % in the UK. A CAN‑bus immobiliser disables the starter and fuel systems at the software layer, stopping thieves even if they relay your key signal.
How the CarGuard CAN Immobiliser Works
- Seamlessly integrates with the vehicle’s CAN network – no cutting OEM wires.
- Requires a hidden, driver‑chosen PIN code sequence on factory buttons to start.
- Blocks engine start, ignition and gearbox until the correct PIN is entered.
- Auto‑re‑arms 30 seconds after ignition off for set‑and‑forget protection.
- TASSA‑certified and insurance‑approved in the UK.
