Car One-Way Wireless Bluetooth Anti-theft Device for 12V Cars Without Factory Remote Control

This Bluetooth car alarm system, model VT-300BT, is designed specifically for 12V vehicles that lack factory-fitted remote control or central locking. It offers a straightforward way to add wireless keyless entry and alarm protection, making older cars more secure without requiring expensive modifications. The one-way wireless communication allows you to lock, unlock and arm the alarm using a Bluetooth-enabled device, providing practical convenience for everyday use. Suitable for all 12V cars, this system is a cost-effective solution for vehicles that originally had no remote control or central locking.

Features and Construction

The VT-300BT is built around a dedicated Bluetooth module that communicates with a paired device, such as a smartphone or remote fob. The system operates on standard 12V automotive power and integrates with existing vehicle wiring.

Bluetooth Connectivity

The one-way wireless link provides reliable keyless entry and alarm arming within typical Bluetooth range. No need for traditional RF key fobs with limited battery life.

Wide Vehicle Compatibility

Works with all 12V cars that do not have factory remote control. For vehicles that also lack central locking, an additional central lock actuator can be added easily.

Alarm Functionality

The anti-theft system includes a built-in alarm that triggers upon unauthorised entry attempts, offering a basic security layer for older vehicles.

Uses and Placement

Ideal for classic cars, budget models, or any vehicle that left the factory without remote locking. The system can also be used as a backup or secondary security measure.

Old Car Upgrade

Perfect for adding modern convenience to older 12V cars that only had manual door locks. No need for complex reprogramming or dealer visits.

Fleet and Commercial Use

Suitable for fleet vehicles where centralised control is not available, as each driver can pair their own Bluetooth device for access.

DIY Installation

The system can be installed by a competent DIYer or auto electrician, following basic wiring instructions for power and door lock actuators.

Benefits and Buying Value
