Nope, no codes or problems. For all it knows the cradle is still there. Just don't cut any wires or short out any contacts. And yes, the plastic cover just snaps right in - it was a perfect fit. You have to do a little coaxing to get the circuit board hidden in the whole but once that's done the cover seals everything up.
