CF618 Universal Smart LCD Remote Key for BMW, Mercedes-Benz, and Audi Key Fob Upgrade

The CF618 Universal Smart LCD Remote Key is a versatile upgrade designed to simplify your car access experience. Built to work with a wide range of makes and models—including BMW, Mercedes-Benz, and Audi—this smart LCD key blends a clear, interactive display with essential remote functions. It’s crafted to reduce clutter by consolidating features into one compact device, helping you lock, unlock, and access your vehicle more conveniently than a traditional key fob.

Benefits & Tips

• Use the LCD screen to quickly verify function status and access car settings on the go, without reaching for your original key fob.
• Compatible with all original cars that feature a one-button start function, expanding your key options while preserving your vehicle’s security workflow.
• Remote start and other advanced functions depend on your original car’s capabilities. The CF618 supports these features where your vehicle already enables them; if not, you can still enjoy keyless entry and automatic window locking on supported models.

Language support: The CF618 provides multi-language capability to suit diverse users, including English, Korean, Japanese, Russian, French, Spanish, Italian, German, Portuguese, Turkish, Arabic, Vietnamese, and Thai. Language adjustment is accessible through the Settings menu on the LCD screen: turn on the key, unlock the screen, slide to Settings, select Language, and choose your preferred option.

Important installation and usage notes: Solder the original key circuit board to the LCD key to complete the installation. This LCD key does not display any car logos, and it does not support changing the lock screen wallpaper. If your car does not support remote start, that function will not operate through the LCD key, though other features like keyless entry may still work on compatible models. If the device does not turn on upon receipt, charge it with the provided cable for 10 hours before first use; only use the original charging cable to avoid damaging the circuit board.
