Keyboard key remapping is basically useless. More often than not, remapped keys revert back to its original function, only to go back to remapped mode after a random period of time. It is like the remapping is handled on the Options software side and the service goes to sleep and doesn't wake up on time. How difficult can it be to keep the remapping on the keyboard side. I develop embedded systems professionally, and I can tell you that is not difficult at all.
