Universal Mobile Phone APP Car Alarm System with Remote Start and Anti-Theft for 12V Cars

This universal car alarm system lets you control your vehicle's door locks and engine start directly from your mobile phone app. It is designed for 12V DC vehicles and includes a one-key start/stop button for convenient engine control. The system also features anti-theft alarm, collision detection, and remote car search functionality. With 433.92MHz wireless frequency and a low quiescent current, it is a practical upgrade for adding modern remote control and security to your car.

Features and Functionality

The system offers a wide range of control and security features that work together to enhance convenience and protection. Below are the key functions supported by the controller and remote keys.

Remote Engine and Door Control

Start or stop your car's engine remotely from your phone or the included two-button remote key. Unlock or lock the doors with a simple command. The one-key start/stop button also lets you control the engine from inside the vehicle. After starting, stepping on the foot brake will automatically lock the doors, and they will unlock when the engine is turned off.

Anti-Theft and Safety Functions

The system includes a silent anti-theft mode, collision alarm, and engine lockup feature to deter theft. Intelligent handbrake and oil pump detection help ensure the car is safe to start. An automatic window closing function is supported when locking the car, but this requires that your car's windows are electric and have a controllable circuit. The collision sensor triggers an alarm if the car is hit.

Additional Convenience Features

You can activate remote boot release if your original car has its own tail box motor. The remote car search function makes the horn sound and direction lights flash, helping you locate your vehicle in a busy car park. Power-off memory and an emergency reset function provide reliability. The remote control also includes a 10-minute timed flame-off safety feature.

Technical Specifications

The system is built to operate in a range of environmental conditions and electrical loads. Key technical details are listed below.

Controller and Remote Key Data

The controller works at an ambient temperature of -40°C to +80°C, atmospheric pressure 86-106KPa, and relative humidity 10%-95%. Its working voltage is DC12V +/- 3V with a quiescent current of less than 15mA. Output current ratings: ACC/ON/START = 30A; turn signal = 5A. High frequency is 433.92MHz. The remote key operates at 3V with a quiescent current of less than 5uA and uses a CR-2032 battery.

Installation and Wiring

The package includes 4 wiring harnesses for installation. A command manual provides wiring details. The crash sensor, LED light, and anti-theft power-off relay are also included for a complete setup. Note that the original car horn alarm notification requires the car to have a control line, or an additional alarm horn can be added.

Benefits and Buying Value

This system offers a straightforward way to add remote control and security features to your car without needing a premium factory system. It is designed for 12V vehicles and supports multiple functions from a single controller.

Reuse and Low Maintenance

The remote key uses a standard CR-2032 battery, which is widely available and easy to replace. The controller has a low quiescent current draw, reducing battery drain when the car is off. The system's power-off memory means settings are retained even if the car battery is disconnected.

Why Choose This Product

If you want to control your car's locks and engine from your phone, and add anti-theft protection without complex installation, this system is a practical choice. It includes all necessary components for a range of vehicles, with support for additional features like remote boot release and window closing where your car allows.
