*The switches that the keypad uses are still being manufactured today. They are C&K D6L90F1LFS and the D6L90F2LFS, they are the exact same. The difference being the force required to push the buttons. One takes 1.3 Newtons and the other 2 Newtons (Pic3). The keypad has 26 of them. Replacing them with new ones will fix the excessive bouncing. When de-soldering the switches one has to be careful of burning the PCB and lifting pads because the traces are very small. | *The switches that the keypad uses are still being manufactured today.
