When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip that is in the key is the right one for the car you have.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and warn you with flashing lights and siren.

If the information does not match, the car will not be allowed to operate.
When a car is connected with a specific fob it will only accept signals from that device. In turn, other fobs won't work with the vehicle even if they look the same.
