If you use a multimeter to test (resistance mode) button 1 2 3 A, the multimeter will beep.

Row 2 3 4 5 B

Row 3 6 7 8 C

Row 4* 0 # D only displays the resistance reading and the multimeter does not beep. No matter it displays the reading or beeps, it means that the line is connected. It is just because the resistance of the buttons in the 2nd row, 3rd row and 4th row is too high, so it will not beep. , the high resistance of the keyboard is indeed an area that needs improvement, but there are methods that can be used to solve it. It does not mean that there is a problem with the keyboard that requires debugging.
