Kia K900 Ghost Door Review: Soft Close Door Cost & Results

Kia K900 Owners: Is Automatic Door Closing Missing?

If you own a 2020 Kia K900, you might have noticed the absence of automatic door closing, a feature often expected in luxury sedans. This can be a minor inconvenience, especially when your hands are full or you're dealing with less-than-ideal weather. Fortunately, the aftermarket offers solutions like the 'Aika Aidoor' system, which can bring this premium convenience to your K900. This review explores the installation, functionality, and overall value of adding a soft-close door retrofit to your vehicle.

What is Ghost Door and How Does it Work?

Ghost Door, or more accurately, an automatic door closing system like the Aika Aidoor, is designed to automatically pull the car door shut once it's within a certain range of the latch. This eliminates the need to slam the door or ensure it's fully closed, providing a seamless and quiet closing experience. It's a feature commonly found in high-end vehicles, but it can be retrofitted to models like the Kia K900. The Aika Aidoor system utilizes the vehicle's existing CAN network for communication, allowing for a stable and integrated function without complex wiring harnesses. This approach ensures reliability and a factory-like feel.

Beyond the core soft-close functionality, the Aika Aidoor system offers additional benefits. For the Kia K900, it includes an automatic hazard light flash when reversing and a password-unlock feature accessible via the driver's door handle button. These added conveniences enhance both the security and user experience of the vehicle, making it feel more modern and sophisticated. The system is engineered to work harmoniously with the car's original electronics, avoiding conflicts and ensuring consistent performance.

Installation Process and Results

The installation of the Aika Aidoor system on a Kia K900 is performed by certified technicians. While this specific installation was completed at 'Today's Car Seoul Branch' in Korea, similar professional services are available for aftermarket installations. The process involves integrating the system's control module with the vehicle's electrical system, primarily through the CAN bus. This method is less invasive than traditional wiring and allows for precise control of the door's automatic closing mechanism.

Installation process:

1. Technicians access the vehicle's CAN network and interior door mechanisms.
2. The Aika Aidoor control unit is connected and integrated with the car's existing wiring.
3. The automatic door closer motor and sensors are installed within the door panel.
4. The system is calibrated to ensure smooth and complete door closure.
5. Final testing confirms all functions, including the soft-close, hazard lights, and password unlock, are working correctly.

After installation, the difference is immediately noticeable. The doors close with a gentle, controlled motion, eliminating the need for force. This provides a premium feel and significantly enhances convenience, especially when carrying items or in situations where a firm slam is undesirable. The added features, like the password unlock, further contribute to the vehicle's overall utility and security. The integration is so seamless that it feels like a factory-installed option.

Is Ghost Door Cost Worth It for Your Kia K900?

The decision to invest in a soft-close door retrofit for your Kia K900 hinges on your priorities. For owners who value convenience, a premium driving experience, and enhanced vehicle features, the Ghost Door system offers significant benefits. The ability to have doors close automatically, coupled with the added security and convenience features, can justify the cost. While the exact Ghost Door cost can vary, the Aika Aidoor system in Korea typically ranges from approximately ₩700,000 to ₩1,000,000 (roughly $500-$750 USD, subject to exchange rates), plus installation fees. Considering the enhancement to daily usability and the perceived luxury it adds, many K900 owners find the investment worthwhile.

Durability is a key consideration. Reputable systems like Aika Aidoor are designed for longevity, with components engineered to withstand the repeated operation of door closing over many years. Regular maintenance is minimal, typically involving ensuring the door seals are clean and lubricated to allow the mechanism to operate smoothly. With proper installation and care, the soft-close door feature should provide reliable service for the lifespan of the vehicle.
