Compact Security for Your Vehicle

The M506 wireless car immobilizer offers a smart and discreet anti-theft solution. Its compact size allows easy installation and use without drawing attention.

The system replaces the oil circuit fuse in your vehicle's engine compartment, ensuring a direct and reliable engine cut-off mechanism.

Effortless Auto-Sensing Remote Control

The lightweight, thin remote control features auto-sensing technology. Simply keep it in your wallet or pocket, and it communicates automatically with the immobilizer without any button pressing.

This hands-free operation allows you to prevent unauthorized use elegantly by ensuring the engine only runs when the remote is nearby.

Enhanced Vehicle Protection Features

If the immobilizer does not detect the remote's signal within 16 seconds of engine start, it will automatically cut off the engine to prevent theft.

Once the engine starts with a remote present, the system does not shut off even if the remote signal is lost afterward, allowing safe operation.

LED Signal Indication and Compatibility

A built-in LED flashes once when the system receives a signal from the remote, confirming normal operation.

This device is compatible with various 12V vehicles, including cars and motorcycles, accommodating a wide range of users.
