Connecting a key fob to a receiver

[Elecinfo28]

Hi all, I am new to this forum and In desperate need of help! I'm currently at university studying product design and part of my design idea has electrical components, unfortunately I am very limited to what I understand electronically so I'm a little stuck. Basically I need to connect two key fobs to a circuit board so they both can be used to power the mother which I have already attached to a battery and a motor. I have attached a photo to help show my attempt so far. If anyone can help with this issue please respond. Any questions let me know. Thanks

Each fob would transmit a digital code. The code tells which button was pushed, and the fob's unique identifier. The identifier is used for security purposes. You don't want all the car key fobs in your neighborhood controlling your device.

This paper illustrates one way to make them secure.

Your question does not make your level of expertise clear. If you need help with basic electricity, or radio transmitters or receivers, please post again.
