Using this keypad

(sorry if wrong section)

Hello,

I found this keypad that works perfectly for a project I'm working on but I'm not to sure how I would get it to work.

I can't find it at all online but it came from an old police dash board computer.

Does anyone have any idea on how I could use this?

Thanks, Alex

Looks like you could set up as a 5x9 with keypad.h
