It does sound like a dirty or bad connection somewhere.
Looking at the price I would try the following on all connections to the board.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
I would also check it for a cold/bad solder joints and bad crimps etc. on the plugs.
Cold solder joints are often a duller gray or have pin holes.
Also sometimes if you wiggle the component you will see the components leg move on the solder side.
A magnifying glass is a big help here.
