Why It Works

Built-In Security, Zero Extra Effort

Designed so your normal routine stays the same. Lock your Lexus - that's it.

Automatic Arming & Simple Disarming

Arms every time you lock your vehicle, as long as the sensor switch is set to ON. No codes, no apps, no extra steps.

In the event you want to disable the alarm while locked (ex. leaving a pet inside momentarily), you can just as easily turn the sensor switch to OFF.

Interior Motion Detection

Detects any significant movement or vibration inside the cabin - whether someone or something enters through a window.

Loud Audible Alert

An immediate, attention-grabbing alarm sounds the moment intrusion is detected, discouraging access and alerting people nearby.

Auto-Disarms on Unlock

Unlock your Lexus with your key fob and the system disarms instantly. Once triggered, only your key can silence the alarm.

Windshield-Mounted Sensor

The discrete sensor mounts on the upper windshield with hidden wiring for a factory-finish look.

Includes Window Stickers

Four "Motion Sensor Alarm" labels are included as a visible deterrent to potential thieves.

Operation Guide

Simple by Design. Powerful in Practice.

Leave the Switch ON

After installation, the sensor's power switch is set to ON and is intended to stay that way.

Lock Your Vehicle as Normal

Use your key fob to lock your Lexus. The system arms automatically within about one minute.

Motion or Vibration Triggers the Alarm

Any interior movement or significant vibration immediately triggers the audible alarm.

Unlock to Silence

The alarm automatically disarms when you unlock the vehicle with your key fob.
