Yes.
I can program or re-program iButton devices ( the key FOBs for gen 1 machines ).
I need to know your keycode.
With that private info, I can then create a key with speed limit of your choice, steering sensitivity of your choice and your keycode.
If you know your keycode, great.
If you don't, I can read it back from any working key that operates your machine.
Let me know how I can assist you.
