Understanding the Lexus Key Fob Window Control

Many Lexus models allow you to control your windows using the key fob, offering both convenience and added security. This feature enables you to open or close all windows simultaneously by holding down specific buttons on your key fob. This is particularly useful for ventilating your car on a scorching summer day or ensuring it’s securely closed before leaving it unattended.

The system utilizes radio frequency signals transmitted between your key fob and your vehicle’s receiver. When you press the appropriate button combination, the signal triggers the window motors to either raise or lower the windows. This technology is seamlessly integrated into your Lexus’s central locking system.
