Dale,
On our 2005 Monterey, the keyless pad reset is tucked in behind an approx 5"x5" wood plate, held on with Velcro, down besides the passenger seat, right side floor, in the coach wall, almost opposite of the outside keypad itself. For us, the panel is just aft of the fire extinguisher by the passenger seat.
Our front door keypad went bad back in 2010 but both the key fobs still work ok.. I did have 1 fob that refused to work with 2 different new button cell batteries, but with swapping the batteries between the fobs and other new cells, we finally got a pair that works consistently from 50' + from the coach..
