BANVIE Car Alarm System — Keyless Entry Kit with 110dB Siren, Shock & Microwave Sensors (12V)

BANVIE Car Alarm System Security Antitheft with Keyless Entry Kit is a universal 12V vehicle alarm package that combines keyless entry, a 110dB siren, shock and microwave sensors, and an engine cut-off relay for enhanced theft deterrence.

Designed for modern 12V cars (excluding older petrol-only models), this kit bundles a zinc-alloy‑framed remote, central locking automation, trunk release, and configurable alarm modes so you can protect your vehicle without complex parts. The system supports power-window close functions on compatible vehicles and includes an anti-hijack cut-off for added safety while driving.

How does the BANVIE alarm deter theft and break-ins?

The system uses multiple detection layers and a loud siren to draw attention and interrupt theft attempts. You can choose audible alarm and silent modes depending on circumstances, and both shock and microwave sensors detect intrusion or movement near the vehicle.

• 110dB siren with six tones to signal different alerts
• Shock sensor senses impacts; microwave sensor senses motion near the vehicle
• Silent alarm option for discreet notifications
• Triggers on side-door opening and other unauthorized access

What keyless and convenience functions are included?

The remote supports standard keyless entry features so you can lock, unlock, flash lights, release the trunk, and initiate car-finding from a distance. If your car supports original auto-window close, the alarm system can command window closing when arming.

• Lock/unlock with remote control and light flash for visual confirmation
• Trunk release via remote button for quick access
• Car-finding (panic) feature to locate vehicle in crowds or parking lots
• Power-window close supported on compatible car models

Can the system disable the engine or protect against hijacking?

Yes — the kit includes an engine cut-off relay that can interrupt ignition or fuel circuits when the system is armed, preventing the vehicle from starting. In certain active scenarios, it can also be used to cut power during suspected hijack attempts if wired and configured accordingly.

• Engine cut-off relay prevents engine start when armed
• Configurable anti-hijack wiring for in-motion protection
• Failsafe wiring and installation recommendations to avoid unintended shutdowns
• Factory-default behaviors can be changed during installation

How does central door locking automation improve safety?

The system can automatically lock doors after you start driving and unlock when the ignition is turned off, helping keep children and passengers secure. This automation is enabled by default but can be switched off if you prefer manual control.

• Auto-locks doors once vehicle is in motion to help prevent accidental opening
• Auto-unlocks when key is turned to ACC OFF for convenient exit
• Option to toggle the feature ON or OFF to match your habits
• Integrates with original central locking circuits for seamless operation

Who is this for? The BANVIE Car Alarm System is aimed at drivers who want a compact, feature-rich antitheft solution that works with most modern 12V vehicles. It’s a good fit for owners who value remote convenience, multi-sensor intrusion detection, and the option to block engine start for theft or hijack protection. Professional or experienced installers will get the most reliable results; if you’re installing it yourself, follow vehicle-specific wiring diagrams and safety precautions to ensure correct operation.
