Transponder Chips
Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the barrel of ignition. 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 prevents hot-wiring or tampering with the vehicle's ignition system to get it started. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is located inside the plastic part of the keys. There are various cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer on the car recognizes this signal as being the correct one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from attempting to alter the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal can still get around this system by using a specific device that intercepts the signal.
As you can see, there are quite a number of advantages to having transponder keys. All car owners should consider this if they wish to protect their investment and reduce theft risk.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding a car or switch on the heated steering wheel. A lot of these additional features may appear convenient however they could make it difficult for you to keep the keys to your car.
Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This signal is encrypted to prevent others from intercepting or replicating the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. Certain models allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver in the car with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car has been paired with a specific fob, it only accepts signals from the device. As a result, other fobs will not work with the vehicle even though they have the same appearance. This ensures the security of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in the service department of a dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for dealers.
