Transponder Chips
If your car was built in the last 20 years, it is likely that it has a transponder chip inside of it. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. The computer auto key programming near me system in the vehicle can then verify that the key's transponder chip is the right one for your vehicle.
This stops the vehicle from being started through hot-wiring or manipulating. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

A circuit within the induction coil emits a signal when the transponder is inserted into ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer onboard the car is able to recognize the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined thief may still be able to get around this system using a special device to detect the signal.

Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding cars, or switch on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna in the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. You can sometimes do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to drive.
After the car has been paired with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even if they look like. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is the service department of a dealer. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed without the need for a dealership.
