Transponder Chips
If your car is made within the last 20 years, it is likely that it has a transponder chip inside of it. It's a small plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This is the reason why hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the key ensures that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and an alarm. This is designed to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to take over the signal.

Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking space, today's key fobs can also switch on a heated steering wheel, or open all windows with a single button push. A lot of these features might seem useful but they could make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent through a small antenna located within the middle of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal.
There are a few different ways to program a key fob, based on the model and make. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or an additional one.
When you press the button on your key fob the microchip inside sends a code to the car's radio that it is linked to. The receiver compared this information to the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car has been connected to a specific fob, it only accepts signals from that device. As a result, other fobs won't work with the vehicle even though they look the same. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need for dealers.
