Transponder Chips Transponder chips are likely to be found in cars that were manufactured within the last 20 years. It's a tiny plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car. This prevents the vehicle from being started through hot-wiring or tampering. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle. Transponder keys look like normal keys, but with caps made of plastic. The chip is housed inside the plastic portion of the key and there are different cuts that can be found on these keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key. A circuit inside the induction coil will emit a signal when the transponder is put into an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start. If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still be able to get around this system employing a device designed to intercept the signal.

Key Fobs In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding the car in a parking lot, today's key fobs can also switch on a heated steering wheel or roll down all windows with just a single click. These additional features could make it difficult to find your car keys. Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal. You can program a keyfob in different ways based on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob. When you press the button on a key fob, the microchip sends a signal to the receiver in the car that it is paired. The receiver compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate. When a car is connected with a specific fob it will only accept signals from that specific device. Other fobs will not work with the car, even if they look like. This safeguards the integrity of the computer system of the car and prevents unauthorized key fobs gaining control of it. Most newer car dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place that has the experience to design the replacement fob is the service department of a dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems — can be programmed by the consumer without the need of dealers.
