When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car.

A circuit within the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and a siren.

The receiver compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it.
