Transponder Chips

Transponder chips are likely to be found in cars manufactured within the past 20 years. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.

This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.

Transponder keys look like normal keys but have caps made of plastic. The chip is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as being the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the car does not recognize the transponder signal as being the right one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure. A determined and skilled thief can still get around this system with a specially designed device that blocks the signal.

Key Fobs

Many of these extra features may seem convenient however they could make it more difficult to keep track of your car keys.

Key fobs communicate with each other and the car using radio frequencies which are transmitted by a small antenna located in the middle of the key. The communication is encrypted, which helps stop others from stealing and replicating the signal.

There are several ways to program a key fob depending on the model and make. Certain cars let you do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.

When you press the button on a key fob, the microchip sends a signal to the receiver in the vehicle with which it is paired. The receiver compares this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.

Once the car is linked with a specific fob, it will only receive signals from that device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.

Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems, can be programmed without the need for a dealership.
