Transponder Chips
If your car was built within the last 20 years, then it contains a transponder chip within of it. It's a tiny plastic thing in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits an unintentional radio signal when 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 car. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.
This stops the vehicle from being started through hot-wiring or altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular metal keys, but with a plastic cap. The chip is contained within the plastic portion of these keys. There are various cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still evade this system using a special device that blocks the signal.

When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver compared this information with the signals that are allowed on the fob and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
After the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place with the experience to design a replacement fob is in the service department of the dealer. However, automotive key programming near me that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
