Soft Key App
I installed this softkey app on both my Polaris and Nike and it works just fine. Unzip it in the windows folder, then it will appear under your settings menu, system tab. You'll have to do a soft reset once the keys are changed.
I think I snagged this from my Universal flashing days but it's stable on our units.
