Transponder Chips
If your car is made within the past 20 years, then it has a transponder chip inside of it. here. 's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started by hot-wiring or tampering. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip itself is housed in the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is put into ignition barrel. The signal will then get received by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
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 a siren. This feature is designed to discourage people from attempting to alter the vehicle, however it is not a foolproof security measure. A skilled and determined criminal may still be able to get around this system using a special device to detect the signal.

Key Fobs

These additional features can make it difficult to locate your car keys.
Key fobs communicate with each with the car via radio frequencies that are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps to keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends signals to the receiver in the vehicle with which it is linked. The receiver compares this information to the signals that are allowed inside the fob, and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is linked with a particular fob, it will only accept signals from that device. This means that other fobs won't work with the vehicle even if they have the same appearance. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most dealerships with newer cars will only deal 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 a replacement fob is in the service department of a dealer. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems, can be programmed without the need for a dealer.
