Transponder Chips

If your car was built in the past 20 years, chances are it contains a transponder chip within of it. It's a tiny plastic thing on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.

When it is activated by an electro-magnetic field the chip emits a low-level signal. This signal is then taken up by an antenna attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.

This prevents the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key also proves that you are the legal owner of the vehicle. This helps to prevent car theft.

Transponder keys appear like normal keys but they have caps made of plastic. The chip itself is housed in 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 key), or a Ford Tibbe key.

A circuit inside the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the computer in the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and an alarm. This feature is intended to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure.

Key fobs communicate with one with the car via radio frequencies that are transmitted by a small antenna located in the center of the key. This communication is encrypted, which helps stop others from stealing and re-transmitting the signal.

You can program a keyfob in different ways based on the model and brand of your vehicle. You can sometimes do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.

When you press the button on a key fob, the microchip transmits a signal to the receiver in the reprogram car key with which it is paired. The receiver then compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to drive.

Once the car is paired with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even if they appear identical. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.

Most dealerships with newer cars will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed car keys by the consumer without the need of an authorized dealer.
