Transponder Chips
Transponder chips are likely be found in cars that were manufactured in the last 20 years. It's a tiny plastic piece inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the car's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This stops the vehicle from being started by hot-wiring or altering the key. The chip inside the car key confirms that the owner is the person who owns the vehicle. This will help reduce car theft.

A circuit within the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer recognizes this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and a siren. This is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief might be able bypass this system by employing a device designed to intercept the signal.

Key fobs today offer more than locking and unlock doors. They can also start the car remotely, make chirping noises to aid in finding a car or turn on the heated steering wheel. A lot of these additional features may seem convenient, but they can also make it harder for you to keep track of your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted through an antenna in the center of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
There are several ways to program a key fob, based on the model and make. You can sometimes do this yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver in the vehicle with which it is paired. The receiver then compares this information with the signals that are allowed in the fob and then either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a specific fob, it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle even if they have the same appearance. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place that has the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, fob key programming for older models with less sophisticated systems can be programmed by consumers without the need for dealers.
