I reckon that's a keypad garage door opener. You could either repair it and make it work again or simply get rid of it. However, I would not recommend doing it yourself since there could be some wires you don't wanna touch. Ask an electrician or a technician to do it for you. I just googled
Garage Door Repair Near Me and found lots of technicians to choose from. Do that as well! By the way, my garage door is moving unevenly, and I'd like to fix it myself. Does anybody know how I could sort this problem out?
