The circuit in the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the car's computer recognizes this signal as being the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.

After the car has been associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even though they have the same appearance.
