Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny plastic thing in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. This signal is then taken up by an antenna attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip that is in the key is the correct one for your specific vehicle.
This prevents the vehicle from being started through either hot-wiring or by tampering. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil emits a signal when the transponder is inserted into ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and skilled criminal could still evade this system by using a specific device that blocks the signal.

When you hit the button on a key fob it transmits a code to the car's receiver it is linked to. The receiver compares this information to the 'allowed' signals stored on the fob and either opens or locks the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car is associated with a particular fob, it will only accept signals from the device. As a result, other fobs won't be able to work with the vehicle even if they look the same. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only accept vehicles that have 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 the dealer. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by consumers without the need for a dealership.
