Have fixed the wiring between the keypad and the main board ... but it seems that the keyboard matrix has started disintegrating ... that's the main issue.

So ... it seems another "quick fix" video is turning into a multi-part series.

I can't easily fix the keyboard matrix ... although I believe it is possible (some sort of conductive ink pen?) ... but I could perhaps rehouse the little machine into another box and create a proper keypad for it using two 4x4 keypads I've got.

Might be an interesting build!
