Altitudeap,

I would try something like this:
[code]
	KeyChanged = 0						' Initialize Key Change bit variable.
 	FirstKey = GET_KEY          		 ' Remember the First Key value seen.

	For i = 1 to 5						' Loop to debounce keypad inputs.
	  theKey = GET_KEY          		  ' Get the current keypad value.
		If theKey <> FirstKey Then		' Detect keypad changes.
			KeyChanged = 1				' Indicate that a key has changed.
		EndIf
	Next i								' Repeat

	If KeyChanged = 1 Then				' Detect keypad changes and...
		theKey = 16					   ' Treat it as if no key was pressed.
	EndIf
[/code]
You will need to declare i and FirstKey as byte variables and KeyChanged as a bit variable.
