Yes !
There are 2 parts to the issue.
Creating a data string.
To do this you need to know your keycode.
1 This can be read back from a working key.
2 This can be known if you have the original records that came with the machine.
3 This was available thru Segway, and may just still be available from some selected dealers.
With that keycode, I can assist you to create a data string.
Once you have a data string, it needs to be written to a standard iButton.
There are several options for DIY or having somebody else do it for you.
