Smart LCD Remote Key for BMW Mercedes-Benz Audi CF799 LCD Display Keyless Entry System

Meet the Universal Smart LCD Remote Key (CF799) — a versatile, modern replacement key designed to bring LCD display, location awareness, and convenient keyless entry to vehicles that include BMW, Mercedes-Benz, Audi, and many other makes. The integrated LCD screen delivers vehicle status at a glance, while smart features such as auto-unlock of the trunk, optional auto window control on compatible models, and anti-loss tracking simplify daily driving and curb common hassles like hunting for keys or misplacing your car.

This universal key is crafted to work across a broad range of models and brands, delivering a single, upgradeable solution instead of juggling multiple fobs. It supports advanced capabilities where available and remains straightforward to install by aligning with your car’s existing key circuit (installation involves soldering the original key circuit board to the LCD key, following the included manual).
