Keyboard keys stopped working

Hi, new to the kano and wasn’t sure where to go to ask. I bought as a Christmas present. My sons Kano keyboard has 2 keys ( the #5 and #6) that just quit working. I have tried the reset button on the keyboard and that doesn’t seem to help. Thought it might have been a low battery too, but that didn’t do it either. Any suggestions out there for me.

The keys might be loose so you might just have to press harder. One of my keys actually feel off and it still would work if I just pressed.
