Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder chip inside of it. It's a tiny piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then received by a specific antenna attached to the ignition barrel. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip is contained in the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit within the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal will then get absorbed 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 disable the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This is designed to deter people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still bypass this system using a special device that detects the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding the car or turn on the heated steering wheel. These additional features could make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located within the middle of the key. The transmission is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver then compares this information to the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to function.
After the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, even though they look similar. This safeguards the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed with out the need for a dealership.
