BANVIE Car Alarm System with Keyless Entry — 12V Vehicle Security Kit, 110dB Siren & Engine Cutoff

BANVIE Car Alarm System Security Antitheft with Keyless Entry Kit is a full-featured 12V vehicle alarm and remote keyless entry package that delivers shock and motion detection, a 110dB siren, engine-cutoff relay and central-lock control to secure most modern cars.

This kit bundles a compact control module, a zinc-alloy-framed remote, sensors and wiring to add layered protection to compatible DC 12V vehicles (excluding older petrol-only systems). The system is designed for easy integration with central-door lock motors, power windows (if factory-supported), trunk release and standard accessory circuits. Settings like silent arm and automatic lock-after-driving are configurable so you can adapt behavior to your driving habits and local regulations.

How does the BANVIE alarm detect unauthorized entries or impacts?

The system uses both a shock sensor and a microwave motion detector to sense tampering and interior movement. If the sensors register a threshold breach, the alarm triggers a loud 110dB siren and can flash lights to draw attention. You can also select silent alarm modes when you need discreet alerts.

• Shock sensor calibrated for knocks and impacts
• Microwave sensor detects cabin motion for intrusion
• 110dB siren with six tones for audible deterrence
• Optional silent alarm mode for unobtrusive alerts

What keyless entry and convenience functions are included?

The remote controller provides standard keyless entry operations: lock, unlock, trunk release and car-finding light flashes. The remote features a zinc-alloy frame and tactile buttons for durability and reliable feedback. If your vehicle supports factory power-window close on lock, that feature can be triggered by the alarm system.

• Lock/unlock and trunk release from the remote
• Car-finder light flash for locating vehicles in lots
• Power-window close supported when vehicle wiring permits
• Durable zinc-alloy framed remote with resilient buttons

Can this system stop the engine or help during a hijack attempt?

Yes — the BANVIE kit includes an engine-cutoff relay that interrupts starter or ignition circuits when armed, preventing the vehicle from starting. While driving, the relay supports an anti-hijack function that can cut engine power if activated under configured conditions. Installation wiring and relay placement determine how these features interact with your vehicle’s electronics.

• Engine kill relay disables starting when armed
• Anti-hijack mode can cut power while running if triggered
• Wiring options let installers choose starter or ignition interruption
• Configurable behavior to match vehicle electrical system

How does central locking automation work with this alarm?

The system can automate central door locking: doors lock automatically after the vehicle begins moving and unlock when the ignition is switched off. This feature helps prevent accidental door openings and can be toggled on or off; factory default is ON. It integrates with existing lock actuators and respects the vehicle’s ACC state for predictable operation.

• Auto-locks after driving starts to secure occupants
• Auto-unlocks when key is turned to ACC OFF for exit convenience
• Feature can be enabled or disabled during setup
• Compatible with most 12V central-lock motor systems

Who is this for: The BANVIE Car Alarm System is intended for drivers and vehicle owners who want a robust, upgradeable anti-theft solution for most DC 12V cars (excluding legacy petrol-only models). It's a good fit for people who need audible deterrence, remote keyless convenience, and an engine-cutoff option — and for installers seeking a flexible alarm module that integrates with existing locks, windows and trunk circuits.
