Transponder Chips If your car is made in the past 20 years, chances are it has a transponder inside of it. It's the tiny plastic piece in 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 it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for your particular car. This stops the vehicle from being started by hot-wiring, or by tampering. The chip inside the car key ensures that the owner is the person who owns the vehicle.

The chip is located inside the plastic portion of these keys. There are a variety of cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start. If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure.

These extra features could make it difficult to locate your car keys. Key fobs communicate with one other and the car using radio frequencies that are transmitted through a small antenna located in the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal. Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. You may be able to do it yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or additional fob. When you press a key fob's button the microchip inside sends an informational code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car's door. If the data does not match the fob's information, the car won't be allowed to run. Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they look like. This is to safeguard the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle. Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. Some aftermarket fobs, usually ones for older models with less advanced systems can be programmed without the need for a dealer.
