Here's an interesting problem. The numerals 6 and 9 have stopped lighting up after pressing the Yale button to insert an access code. None of the other digits have dimmed noticeably, but 6 and 9 are completely black. Pressing them (or where they would be) still work fine. I can deal with 20% of the digits being dark, but it's an Airbnb rental. I'd rather not assign only codes that don't include those two digits!
