The 2026 KEYDIY KD-X6 is a new-generation standalone automotive key programming and locksmith tool designed for professional locksmiths. Compared with the previous KEYDIY KD-X4, the KD-X6 offers built-in DoIP, integrated MLB and MQB48 functions, Mercedes-Benz FBS3 support, and Cloud-C remote functionality.
The KEYDIY KD-X6 is available in two configurations: Standard Version and Full Version. Understanding the difference between these two versions can help locksmiths choose the right configuration for their needs.
KEYDIY KD-X6 Standard Version vs Full Version
The main difference between the KD-X6 Standard and Full Version is the included software authorization and accessories.
The KD-X6 Full Version includes all available authorizations, providing access to the supported functions without requiring separate license activation.
The Full Version also includes:
- All available KD-X6 authorizations
- KD-MOTO adapter
- Benz FBS3 adapter
- Built-in DoIP
- Built-in KD-MP MLB & MQB48 functions
- Benz FBS3 Add Key & AKL support
- Cloud-C remote function
This configuration is ideal for professional automotive locksmiths who want a more complete all-in-one solution.
The KD-X6 Standard Version is designed for users who do not need all available functions immediately.
Some functions require separate license activation, allowing users to purchase or activate additional functions according to their requirements.
The KD-MOTO adapter and Benz FBS3 adapter are also sold separately with the Standard Version.
For locksmiths who only need specific functions, the Standard Version can be a more flexible option.
KEYDIY KD-X6 vs KD-X4: What Are the Differences?
The KD-X6 is more than just an upgraded version of the KD-X4. It introduces several important changes designed to make professional key programming more convenient.
1. Standalone Key Programming Device
One of the biggest differences is that the KEYDIY KD-X6 is a standalone device.
The KD-X6 does not require a PC or mobile phone for normal operation. Its integrated hardware and software provide a more convenient solution for locksmiths working in workshops or on-site.
2. Built-in DoIP
The KD-X6 has built-in DoIP.
DoIP, or Diagnostics over Internet Protocol, is increasingly used on modern vehicles. Having DoIP integrated into the device can simplify communication with supported vehicles and reduce the need for additional hardware.
3. Built-in KD-MP MLB & MQB48 Functions
The KD-X6 also integrates KD-MP MLB and MQB48 functions.
Unlike the KD-X4 setup, these functions are built into the KD-X6 and do not require an additional license.
This makes the KD-X6 a more convenient option for locksmiths working with supported VAG MLB and MQB48 key programming applications.
4. Mercedes-Benz FBS3 Add Key & AKL
Another major upgrade is Mercedes-Benz FBS3 support.
The KD-X6 supports:
- Mercedes-Benz FBS3 Add Key
- Mercedes-Benz FBS3 AKL (All Keys Lost)
The FBS4 and FBS5 functions are also currently under development, which could further expand the KD-X6’s Mercedes-Benz coverage in the future.
5. Cloud-C Remote Function
The KEYDIY KD-X6 supports the Cloud-C remote function, adding another useful capability for professional locksmiths.
This gives users more options when working with supported remote/key applications.
