The signal is received by the chip which sends a signal to the vehicle. If the computer on the car detects this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.

The receiver compares this information to the signals that are allowed in the fob and then either opens or closes the door. If the data does not match the fob's information, the car won't be allowed to operate.
Once the car is paired with a specific fob it will only receive signals from the device that is associated with it.
