Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your vehicle.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble regular metal keys but have caps made of plastic. The chip 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) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer in the car is able to recognize the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and will notify you via flashing lights and a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief may still be able to get around this system employing a device designed to take over the signal.
You can see that the transponder is an excellent option. Every car owner must take this into consideration 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 turn on the car remotely, make chirping noises to aid in finding the car, or turn on the heated steering wheel. Many of these extra features may appear convenient however they could make it difficult for you to keep track of your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted through an antenna in the center of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
There are several ways to program a key fob based on the model and make. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on your key fob it transmits an informational code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' stored on the key fob and then it opens or closes the car door. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they look identical. 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 deal with cars that have original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less advanced systems, can be programmed without the need for a dealership.
