Transponder Chips
If your car was built within the last 20 years, chances are it contains a transponder chip within of it. This is a little plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your vehicle.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained within the plastic part of these keys. There are several different cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.

A circuit inside the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined criminal might be able escape this security system by using a special device to intercept the signal.

Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it harder for you to keep track of your car keys.
Key fobs communicate with each other and the car using radio frequencies which are transmitted through a small antenna located in the center of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
There are several ways to program a key fob, based on the vehicle's model and make. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the car that it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to function.
Once the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, despite the fact that they look similar. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied 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's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by consumers without the need of a dealership.
