Transponder Chips
If your car was manufactured in the last 20 years, it is likely that it has a transponder inside of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your specific vehicle.
This stops the vehicle from starting by either hot-wiring or by altering the key. The chip inside the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys resemble regular metal keys, but with caps made of plastic. The chip is inside the plastic part of the keys. There are a variety of cuts: 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 will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will warn you with flashing lights and siren. This function is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief could still be able to bypass this system by using a special device to detect the signal.
As you can see there are quite number of advantages to having transponder keys. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start your 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 more difficult to keep track of your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted by a small antenna located in the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
There are many ways to program a key fob, based on your vehicle's make and model. You can sometimes do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens the car door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to function.
Once the car has been paired with a specific fob, it only accepts signals from the device. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This ensures the security of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place with the knowledge to create an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
