Help hack a remote to Minnkota marine motor

I need help with the wireless remote. It is powered by a CR2032 battery or 3v. When taken apart it looks like the buttons use conductive material to close the circuit. I simply want the arduino to open and close the 3v circuit for the left/right/forward buttons.

I'm basic when it comes to power on the arduino. Can someone spell out some ways to solve the problem?

You can do simple hacks to a remote control like below.
