Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder chip inside of it. It's a tiny plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is received by a specific 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 vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to start it. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

A circuit within the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer onboard the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and siren. This feature is intended to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure.

These extra features could make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent by a small antenna in the middle of the key. This signal is encrypted to prevent others from stealing or modifying the signal.
There are several ways to program a key fob, based on your vehicle's make and model. You may be able to do it yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is linked. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's doors. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a particular fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even though they appear similar. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. Some aftermarket fobs, usually ones for older models that have less advanced systems can be programmed with out the need for a dealership.
