I purchased 5 of these keypads and tested 2. Both are junk. To make them respond you need to POUND on the keys. If you dont have a means to confirm what key was pressed you will get erroneous data because the key press may not register.
In the past MPJA sold the 18316-SW Keypad which was far superior to this version.
Because this is arduino compatible, I was able to make a door lock with this keypad. Thanks MPJA!
