Advanced Vehicle Security

The CHADWICK wireless immobilizer car engine lock is a sophisticated anti-theft system designed for 12V vehicles. It replaces the original relay with minimal effort and no wire damage, securing your car against unauthorized use with a hidden relay-shaped design.

Its dual operation modes—hidden lock and anti-hijacking—offer flexibility to suit your security needs, automatically controlling the vehicle's fuel circuit to prevent theft.

Dual Mode Operation

The device allows you to switch between manual mode and anti-robbing mode without needing to operate in the automatic induction mode. In hidden lock mode, the unit disables engine start unless the correct signal is received once after ignition.

In anti-hijacking mode, the device continuously monitors for the remote control signal while driving and cuts engine power within one minute if the signal is lost, enhancing in-motion vehicle protection.

Non-Destructive & Easy Installation

This immobilizer is designed for a seamless replacement of your vehicle's relay. It installs invisibly without altering original wiring or damaging your car’s electrical systems, ensuring a fast and convenient setup.

The original vehicle relay power is used to control an internal switch coil, preserving all other vehicle functions intact.

Reliable Performance and Safety

The unit features anti-shielding and anti-interference chip technology for stable operation. It supports normal start and stop functions and senses the correct password signal to authorize engine ignition within preset time intervals.

It automatically cuts off the fuel supply shortly after the flame is turned off and reopens it when the user with the remote control approaches, within a 15-meter sensing radius.

Unfortunately, it does not fit the Kia Sportage NQ5. The housing is too large and the base is too tight. The feet fit at the correct spacing, but nothing else fits. It's a pity.
