1. Introduction
The CF618 Pro Universal Remote Smart LCD Key is an advanced car key replacement designed to enhance your driving experience.

2. Setup
2.1 Compatibility
The CF618 Pro LCD Key is suitable for all original cars equipped with a one-key start function. It is not suitable for vehicles that use manual direct-plug car keys.
2.2 LCD Key Installation
The installation process involves transferring the circuit board from your original remote key to the CF618 Pro LCD Key and connecting the wiring harness. This process typically takes around 15 minutes.
- Prepare one original remote key.
- Carefully open the original remote key and remove its circuit board.
- Take out the provided wiring harness. Connect the wires according to the rubber ring color coding.
- Weld the corresponding wiring harness to the battery position on the circuit board. The red cable is for positive (+), and the black cable is for negative (-).
- Weld the wiring harness for the unlock jack, trunk, and multifunction buttons to their corresponding points on the original key circuit board. Ensure welding is done on the button foot; there is no need to separate positive and negative connections for these.
- Insert the circuit board with the welded wiring harness into the LCD key in the correct orientation.
- Place the provided sponge padding under the welded circuit board for protection.
- Close the LCD key casing and secure it with screws.
2.3 Car Fragrance System Installation
The car fragrance system features an adhesive hidden installation, eliminating the need to disassemble your car or drill holes.
- Identify a suitable hidden location in your car, such as under the seat or in the glove compartment.
- Clean the surface where the aromatherapy control box will be attached.
- Peel off the protective backing from the adhesive pad on the aromatherapy control box.
- Firmly press the control box onto the chosen surface to secure it.
- Insert the desired aromatherapy scent into the control box.
3. Operating Instructions
3.1 LCD Key Functions
- Touch Screen Interface: Navigate through menus and control functions using the fully laminated glass touch screen.
- Language Switching: The key supports 12 languages: English, Chinese, Korean, Russian, Spanish, Portuguese, French, German, Italian, Japanese, Thai, and Traditional Chinese. You can change the language through the key's settings menu.
3.2 Comfort Access System
The comfort access system allows for automatic locking and unlocking of your vehicle based on proximity:
- When the smart LCD key approaches the car (0-2 meters), the car will automatically unlock.
- When the smart LCD key moves away from the car (3-5 meters), the car will automatically lock.
3.3 Automatic Window Control
For compatible car models, the LCD key can control your car windows:
- If your original car key can lock the car and operate the windows from a distance of 10 meters, the LCD key can also operate the automatic window lock function.
- Some original car models may only allow window operation within 5 meters, and the automatic window function may not be available.
- Important: This function requires your original car to support locking the car or long-pressing the lock button to lift the windows.
3.4 Car Fragrance System Operation
The integrated car fragrance system provides air purification and a pleasant scent in your vehicle. It can be controlled directly from the LCD key.
- The system features negative ion purification to decompose odors.
- The balm starts and stops with the car, ensuring continuous fragrance when the vehicle is in use.
- Control the fragrance intensity and on/off function via the LCD key's interface.
3.5 Anti-Lost Function
The LCD key includes an anti-lost function. You can input your owner information (e.g., phone number) into the key, which can be displayed on the screen to help facilitate its return if lost.

5. Troubleshooting
