Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's a tiny piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that 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 by manipulating. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car detects the signal as correct it will turn off the car immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.

A lot of these features may appear convenient, but they can also make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. automotive key programming is encrypted, which helps to keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You may be able to do it yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob it transmits a code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car's doors. 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 the device that is associated with it. Other fobs will not work with the car, even though they appear similar. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Some aftermarket fobs, usually those for older models with less advanced systems can be programmed with out the need for a dealership.
