New Post: FA (translate ZPK from ZMK to LMK) command with single length keys

Has anyone got the FA command to work using single length keys?
I get FB10 returned which suggests there is an issue with the ZMK.

See example below where I also include the keys and how they were generated at the console.:

ZMK (plain full key) 9DDC9BAE925D31E6
KCV: 0EB795

Plain ZPK: ABDC5476102301FE
KCV: 6C5A CF

ZPK encrypted under ZMK is 76E565ADB1062E6E

------console to create ZMk from encrypted components-------------
EC
Key Type: 000
Key Scheme: 0
Enter component: 43455E25297CD946
Encrypted Component: 42D51505B7CFC461
Key check value: 428C 48
EC
Key Type: 000
Key Scheme: 0
Enter component: 834CDF1052761FBA
Encrypted Component: 9FB1185F9741502A
Key check value: D6FC F1
EC
Key Type: 000
Key Scheme: 0
Enter component: 5DD51A9BE957F71A
Encrypted Component: 619E36FE513CEA21
Key check value: EEC6 6C

FK
Key length [1,2,3]: 1
Key Type: 000
Key Scheme: 0
Component type [X,H,E,S]: E
Enter number of components (2-9): 3
Enter component #1: 42D51505B7CFC461
Enter component #2: 9FB1185F9741502A
Enter component #3: 619E36FE513CEA21
Encrypted key: 2B77 B300 B254 94A2

Key check value: 0EB7 95

So the ZMK under LMK 04-05 is 2B77 B300 B254 94A2

So for the FA command:
send:
ABCDFA2B77B300B25494A276E565ADB1062E6E

Response:
ABCDFB10

If anyone can shed any light on this it will be much appreciated?

thanks.
