Transponder Chips
If your car was manufactured within the past 20 years, then it contains a transponder chip within of it. This is a little plastic piece inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for your particular car.
This stops the vehicle from being started through either hot-wiring or by altering the key. The chip inside the car key verifies that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is housed within the plastic part of the key and there are a few different types of cuts on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and determined thief can still get around this system by using a specific device that detects the signal.
You can see that a transponder is a great option. Every car owner must take this into consideration if they wish to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding cars or turn on the heated steering wheel. Many of these extra features may seem convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted to prevent others from stealing or stealing the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob or additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the car with which it is linked. The receiver compared this information to the 'allowed' signals in the fob and then either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate.
When a car is connected with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place with the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
