Transponder Chips
If your car was manufactured within the last 20 years, chances are it contains a transponder chip within of it. It's a small piece of plastic in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip in the key is the correct one for your specific vehicle.

This stops the vehicle from being started through hot-wiring or tampering. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief could still bypass this system by using a specific device that detects the signal.

These extra features could make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps to stop others from stealing and replicating the signal.
There are many ways to program a key fob, based on your vehicle's model and make. It is possible to do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compares the information with the permitted signals stored in the key fob, and then locks or opens the car door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. This means that other fobs won't be able to work with the vehicle even if they have the same appearance. This protects the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in a dealer's service department. Some fobs from the aftermarket, especially those from older models that have less advanced systems can be programmed without the need for a dealer.
