Transponder Chips
Transponder chips are likely be found in cars manufactured within the last 20 years. It's a tiny piece of plastic in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for the car you have.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also verifies that you are the legal owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the onboard car computer detects this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This is designed to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined criminal might be able escape this security system by using a device that can take over the signal.

Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all windows with a single button click. These extra features can make it difficult for you to locate your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located inside the middle of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. It is possible to do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits an informational code to the car's radio that it is paired with. The receiver then compares this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the information doesn't match, the car will not be allowed to run.
When a car is connected with a specific fob, it will only receive signals from that specific device. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically ones for older models that have less advanced systems can be programmed without the need for a dealership.
