Batboard

I have a uhf sys saber 3 whose codeplug was corrupted. repaired codeplug and programmed several zones and modes- now keypad won't work. while likely keypad shield is ng, anything else i should look for?
if i have to replace keypad shield, whats the part #?
is it cheaper to flat rate it?
will motorola repair a systems saber without causing grief? [email protected]
