Advanced Wireless Engine Protection

Designed for 12V gasoline vehicles, this wireless immobilizer secures your car engine by controlling the fuel circuit to prevent unauthorized starts. Its relay-shaped design allows seamless replacement of the original relay without damaging the car's wiring, maintaining the vehicle's integrity and performance.

Dual Operation Modes for Enhanced Security

Switch effortlessly between hidden lock mode and anti-hijacking mode to suit your security needs. Hidden lock mode allows normal driving after remote signal detection without interruption, while anti-hijacking mode continuously monitors signal presence, stopping the engine if the signal is lost to prevent theft or hijacking attempts.

Hidden lock mode requires re-sensing after engine off.
Anti-hijacking mode cuts engine if remote signal lost over 1 minute.

Intelligent Sensor and Signal Processing

The unit scans sensor ID passwords during engine start cycles, progressively shortening verification time for convenience. If an unauthorized start is detected, the fuel circuit cuts off automatically, ensuring your vehicle remains protected against theft attempts.

First start scan time: 25 seconds
Second start scan time: 20 seconds
Third start scan time: 10 seconds

Non-Intrusive Installation and Compatibility

Installation involves replacing the original vehicle relay without cutting wires, preserving existing electrical systems. Compatible with various relay shapes—choose Model A by default or Model B if unavailable—to fit different vehicle designs.

No damage to original wiring
Fits different vehicle relay shapes

Reliable Electrical and Anti-Interference Performance

Featuring stable chips with anti-shielding technology, this immobilizer operates with low power consumption: about 20mA for the unit-relay and 5mA for the remote controller. Remote control uses a CR2032 battery ensuring long-lasting operation.

Unit-relay load current: 30A–40A depending on model
Remote operates on CR2032 battery

It replaces the original vehicle relay without cutting any wires, ensuring non-destructive and quick installation.

03 What are the main anti-theft functions?

It features a hidden lock mode and an anti-hijacking mode to prevent unauthorized engine start and theft.

04 How does the hidden lock mode work?

In hidden lock mode, after receiving the remote control signal, the engine runs normally without turning off during driving; sensing is required again after engine shutdown.

05 What happens in anti-hijacking mode?

The unit continuously checks for remote signals during driving and shuts off the engine if the signal is lost for more than one minute.

06 Does it affect other vehicle systems like doors or lights?

No, it only controls the fuel or oil circuit to prevent engine start and does not control doors or lights.

07 What is the sensing distance for automatic fuel cut-off?

The device senses the remote control signal at about 15 meters to automatically cut off fuel when the engine is off.

08 What is included in the package?

The package includes 1 unit-relay, 2 induction remote controls, and 1 user manual.

09 What are the electrical requirements?

The unit-relay works at approximately 20mA with load currents of 30–40A depending on model; the remote control uses a CR2032 battery.

10 Is the device affected by interference or shielding?

The immobilizer uses anti-shielding and anti-interference technology with a stable internal chip for reliable operation.
