Simple on/off Switch Application Using Two 433MHz Radio Tinyshields

Hello, I'm currently building a demo that simulates a door of a vehicle locking and unlocking controlled wirelessly via key fob.

I have a key fob enclosure where I will fit a 433MHz long range radio Tinyshield stacked with a Tinyduino processor board and lithium battery. In the simulated vehicle, I will have a similar configuration. When the user presses button "A" on the fob, I want it to send a signal to the vehicle's RF Tinyshield where the Tinyduino processor it's mounted to will output signal "A" (in my application, "lock vehicle"). When the user presses button "B" on the fob, I want the vehicle's Tinyduino to ultimately output signal "B" (in my application, "unlock vehicle").

In short: User presses button A on key fob, switch in vehicle closes. User presses button B on key fob, switch in vehicle opens.

Please see the attached (informally written) flowchart for clarification.

Are there any examples I could use to do something basic like this? The only examples I could find were much more involved and used other components such as the Tinyscreen. So far, I found only two examples using the radio Tinyshield which were "Robot_Control_Kit_Receiver" and "TinyPaintballWatch". Unfortunately, it's difficult to reference to these since they use additional libraries and components. Since my application is A LOT more simple than those examples, I'm not sure which libraries I need. Any help is greatly appreciated!
