Givi top box/Silca EU5r issue with code

[kobblers]

These Givi keys normally have 3 digits and I normally cut them to code using the Eurolocks 25001-27000 but this key has 4 digits but appears to use the same blank?

I've decoded the bitting as 4321122 and Instacode says the code for this bitting is 26364 which doesn't match the code on th key.

Is anyone aware of another series that uses the EU5r blank?

Cheers. Rick.
