Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. auto key programming 's a small plastic thing on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your vehicle.
This stops the vehicle from starting by hot-wiring or tampering. The chip in the car key confirms that the owner is the one who owns the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is contained inside the plastic portion of the key, and there are different types of cuts on these keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil emits a signal when the transponder is inserted into an ignition barrel. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and warn you with flashing lights and a siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief might be able escape this security system by using a special device to intercept the signal.

Key Fobs
Key fobs today offer more than locking and unlock doors. mobile key programming can also turn on the vehicle remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. These extra features can make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are sent by a small antenna in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in different ways based on the make and model of your vehicle. It is possible to do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends signals to the receiver in the vehicle with which it is paired. The receiver compares the information with the permitted signals stored on the key fob and then locks or opens the car door. If the information isn't in line an chirping sound is heard and the car isn't allowed to function.
When a car is connected with a specific fob it will only receive signals from that specific device. As a result, other fobs will not work with the vehicle even though they appear similar. This protects the integrity of the computer system in the car and prevents unauthorized key fobs gaining control of it.
The majority of newer dealerships will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare an appropriate replacement fob is a dealer's service department. Some aftermarket fobs, usually those for older models that have less sophisticated systems, can be programmed without the need for a dealer.
