So, how do garage doors work? When you push the button on your garage door opener remote or inside your garage, the transmitter sends a code to the receiver, which is tuned to the same frequency as the transmitter.
For security purposes, modern operating systems also include a controller chip that creates a hopping code or rolling code, which means the code used is different each time the door opens or closes. This chip has a memory capacity that can hold up to one trillion possible codes, depending on the system. Both the receiver and the transmitter use a synchronized random number generator to choose a new code each time you press the button to open or close the door.
If your receiver ever gets a code that it does not expect from the transmitter, the garage door will not open. This prevents thieves from breaking in by hacking your opener system. If you or someone else does for some reason press the transmitter times, your transmitter and receiver will no longer be synchronized, and therefore your remote control will no longer work.
Newer systems include more codes, as well as longer codes, so the newer your system is, the less likely it is for another transmitter to open your garage door. There is no way for a person to predict the random code that the transmitter and receiver will create for each operation, and code capturing is ineffective because the system will never use the same code twice.

Doors in the s were easy targets—they used only one code.
