When activated by an electro-magnetic field the chip emits a low level signal.

A circuit within the induction coil will emit an electrical signal when the transponder is put into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer onboard the car detects the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm.

If the information doesn't 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 that specific device. In turn, other fobs won't be able to work with the vehicle even if they look the same.
