KEYDIY KD X4 is a powerful key programming tool, widely used by UK locksmiths and auto technicians. Here’s a quick and clear update on 5D and 5C key support and the latest KEYDIY chip solutions.
Current 5D Key Requirement (Important)
At present, when programming 5D keys, customers must have an original OEM 5D key. This is required for successful key addition and data reading.
Upcoming KEYDIY 5D Key Solution – FGB Series
KEYDIY is developing the FGB series key boards, which will allow users to:
- Generate BMW smart keys
- Generate 5D keys directly
- Improve flexibility without relying only on OEM keys
This will significantly expand KD-X4 capabilities for professional users in the UK market.


5C Key Solution – ZB Series Chips
For 5C keys, KEYDIY provides the ZB series chips, which can directly generate 5C keys and are easy to use with KD-X4.

How to Identify FGB vs ZB Chips
You can easily tell the difference:
- FGB series → Two chips on the board (supports BMW & 5D key generation)

- ZB series → One chip only (used for 5C key generation)

No special tools are required to identify them — a visual check is enough.
