LockCar One Plus complete review every feature explained for UK drivers

The LockCar One Plus integrates a hardwired 20A relay immobiliser, AES-128 encrypted proximity tag and app authentication, 4G module with real-time GPS tracking, a forward-facing dashcam, 24/7 parking mode with cloud footage backup, and remote immobilisation capability, all managed by the AZFO MCU from one installation.

The 20A relay is rated for the full range of passenger car and light commercial vehicle start circuits. The proximity tag communicates over a 2.4GHz encrypted channel, separate from the vehicle’s keyless entry frequency. GPS updates are available as frequently as every few seconds while the vehicle is in motion. The 4G module maintains a continuous data connection using an embedded SIM.

The LockCar app on iOS and Android provides access to every One Plus function: live GPS tracking, live camera stream, movement and geofence alerts, remote immobilisation, journey history, speed camera alerts, and system status. All functions accessible from one interface without multiple apps or subscriptions.

Against relay attack, the relay immobiliser provides complete protection. A relay attack that satisfies the factory keyless entry system, unlocks the doors, and attempts to start the engine encounters the LockCar relay in the start circuit. The relay is open. The engine does not start. The attack fails at the final step regardless of how completely every factory security check was satisfied.

Against CAN bus injection, the relay immobiliser provides equivalent protection. CAN bus injection attacks send commands to the ECU over the vehicle’s internal network. The LockCar relay is outside the CAN bus entirely. No CAN bus command can open or close the relay. The engine does not start.

Against tow-away theft, where the vehicle is loaded onto a flatbed and removed without starting, the 4G GPS tracking in One Plus provides the response capability. A movement alert reaches the owner’s phone within seconds. Live GPS location is immediately available to share with police.

Against key cloning, OBD programming, or any other method that attempts to create or use a new key, the relay immobiliser is equally effective. Regardless of whether a new key has been created, the LockCar relay remains open. The vehicle does not start until the correct LockCar authentication is provided.
