Control 3 arduino device with IR remote

My questions:

1. What are the most used transmitters / button box
2. Will they all send the same signal? So if i press one button al 3 devices will arm or disarm?
3. If question 2 is true, then what is the best way to let each transmitter control just 1 Alarmbox.

1. The most used IR transmitter is your TV remote control. What do you consider to be a "button box"? I have no clue.

2. Just like your TV remote they all send a code depending on what button you press. Are you considering making your own remote?

3. The answer is in the program code you write.
