Question
I want to program a key for a Honda motorcycle using KEYDIY KD-X4. Do I need to purchase an additional adapter or a paid license?
EOBDTool.co.uk Engineer’s Reply
Yes. When using KD-X4, you need to purchase KD-MOTO Motorcycle Adapter separately.2000 KD Coins are required for this function as well. (KD coins can be obtained with KD remote)
If you plan to use the upcoming KD-X6 Professional Version, KD-MOTO Adapter is included, so there is no need to buy it separately. You can use the device directly, no need extra activation cost.

Which One Should You Buy?
- For Honda motorcycle key programming only → KD-X4key programmer is the most cost-effective choice.
At £520, KD-X4 has the lowest entry price. Even after adding KD-MOTO Adapter, it can still be a more economical option if you only need motorcycle key programming.
- For a newer platform and more functions → KD-X6 Standard.
At £1,172, it costs considerably more than KD-X4, so it makes more sense if you also need the newer KD-X6 functions.
- For professional locksmiths → KD-X6 Professional/Full.
At £1,719, it is the most expensive option, but it includes more advanced functions and accessories. If you regularly perform different types of key programming, the additional cost may be worthwhile.
Simple recommendation:
- Lowest budget:KD-X4
- More KD-X6 functions:KD-X6 Standard
- Full professional setup:KD-X6 Professional/Full
