The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer on the car recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.

If the information doesn't match the fob's information, the car won't be allowed to run.
After the car has been associated with a particular fob, it will only accept signals from the device. In turn, other fobs won't work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the knowledge to create the replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed without the need for a dealer.
