## Description

CHADWICK Car Immobilizer Anti-Theft Alarm System, M506 Wireless Engine Lock, Auto Anti-Robbery Device, Intelligent Circuit Cut Off Tool, Universal 12V Car Alarm + 2 Remotes, for Car, Motorcycle

## Features

- Anti-Theft Alarm System with Auto-Sensing The remote control features Auto-Sensing Technology, allowing hassle-free operation. Simply keep the remote in your wallet or a discreet location—no manual input required. This discreet design ensures your car’s security remains undetectable, even to close friends. Politely decline unauthorized car borrowing and deter thieves with this invisible safeguard
- Circuit Hidden Lock Mode (Default – Recommended for Stability) Factory default setting (no short-circuit ring inserted). Engine stays active once started, even if the remote signal is lost during driving. How it works: After ignition, the system requires a remote signal within 16 seconds to keep the engine running. If no signal is detected, the engine shuts off only during startup—never while driving. Ideal for most vehicles to prevent accidental engine cutoffs caused by signal interruptions
- Anti-Robbery Mode (Advanced – Use with Caution): Activated by inserting the short-circuit ring (included). Engine requires continuous remote signal reception while driving. If the signal is lost for 30 seconds, the engine shuts off. Important: This mode may not suit all vehicles (e.g., those with Bluetooth interference). If your car experiences unintended shutdowns while driving, switch back to Hidden Lock Mode (remove the short-circuit ring).
- Effortless DIY Installation: Install in minutes! Simply: Locate your car’s fuel pump fuse (under the hood). Replace the fuse with the M506 main unit. Secure the device and close the hood. Pro Tip: Store the original fuse safely for future use
- Safety Reminder:Test modes in a safe environment before regular use. Avoid Anti-Robbery Mode if your vehicle experiences signal instability. The default Hidden Lock Mode provides reliable theft prevention without driving risks
