Transponder Chips

If your car was manufactured in the last 20 years, chances are it contains a transponder chip within of it. This is a little plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car.

This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.

Transponder keys look like regular keys made of metal but have a plastic cap. The chip is contained in the plastic portion of the key, and there are different types of cuts on these keys: a cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it's not a 100% security measure.

These additional features can make it difficult for you to locate your car keys.

Key fobs communicate with one other and the car using radio frequencies which are transmitted through a small antenna located in the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your car. You may be able to do it yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.

When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' stored in the key fob and then it opens or closes the car's door. If the data does not match the signals, the car will not be allowed to run.

Once the car is linked with a particular fob, it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle even though they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by customers without the need for a dealership.
