Advanced Car Engine Security
The M501 Model A wireless immobilizer locks your 12V gasoline vehicle’s engine by cutting off the fuel circuit if unauthorized start attempts are detected. This anti-theft system increases vehicle security without altering original wiring.
This intelligent device uses a relay-shaped design that replaces the original vehicle relay with no damage or modification required, enabling fast, invisible installation.
Multiple Operating Modes
Switch seamlessly between manual control, automatic induction, hidden lock, and anti-hijacking modes to customize your vehicle’s security. The hidden lock allows driving after signal reception without re-sensing until the engine is turned off.
Anti-hijacking mode monitors the remote control signal continuously during driving and will stop the engine if the signal is lost for more than one minute, enhancing on-road protection.
Reliable Engine Start Verification
Engine start attempts are verified by scanning a sensor ID password. The device allows up to three shortened scanning intervals to confirm correct password presence.
If the correct signal is not recognized within these intervals, the fuel circuit is cut off and the engine stops, effectively preventing unauthorized use.
Stable Performance and Compatibility
Equipped with anti-shielding and interference-resistant technology, the chip maintains stable operation to reliably secure your vehicle.
Designed exclusively for 12V gasoline cars, the unit works with different vehicle relay shapes by replacing the original relay without interfering with other car systems.

Currently, it's still in the testing phase, so I can't say whether it will work in some time. 😁

It does not work properly on a consistent basis, it fails very often and you are unable to start the car even if you have the key; you have to remove the original one and replace it.
