Transponder Chips Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own. When activated by an electro-magnetic field the chip emits a low level signal. The signal is then received by a specific antenna that is attached to the barrel of ignition. 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 is the reason why doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the key also confirms that you are the legal owner of the vehicle.

The chip itself is housed within the plastic part of the key and there are a few different cuts that can be found on these keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start. If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and alert you with flashing lights and an alarm.

A lot of these features might seem useful, but they can also make it more difficult to keep the track of your car keys. Key fobs communicate with one other and with the car through radio frequencies that are transmitted through a small antenna located in the center of the key. This signal is encrypted to stop others from intercepting or replicating the signal. You can program a keyfob in different ways based on the make and model of your car. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob. When you hit the button on a key fob it transmits a code to the car's receiver that it is linked to. The receiver then compares this information with the 'allowed' signals in the fob and then either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to run. Once the car is connected to a specific fob, it can only receive signals from that device. This means that other fobs will not work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it. Most newer car dealerships will only work with cars that have original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the knowledge to create an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems — can be programmed by customers without the need of a dealership.
