Swapping keypads probably won't be a good thing, The keypads are programmed as to what loads they control, so the relocated keypad would still do what it did where it came from. I'm not sure I said that quite right but hopefully you know what I was trying to say.
First try - The easiest way to reset the keypad is to turn your "Salesman switch" off and then back on. After you do, you will need to turn on your AquaHot, water pump, hot water dispenser, any fan switches, and the GEM lights switch for the lights over the bed, and any other things you normally leave in the "ON" position, as that will leave all of your Intellitec loads "OFF". But that should re-set that keypad.
We have that problem from time to time on the six-button keypad in the bathroom on our '06 Dynasty.
Let us know if that gets you going again.
