Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. It's the small piece of plastic in the head of your car key that contains 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 level signal. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.
This stops the vehicle from starting by hot-wiring or tampering. The chip inside the car key ensures that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys but have caps made of plastic. The chip is housed inside 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 known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is placed in the ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the onboard car computer detects this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and an alarm. 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 determined thief could still be able to escape this security system by using a device that can detect the signal.
As you can see there are quite a few advantages to getting a transponder key. This is something that all car owners should think about if they want to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding the car in a parking lot keys of today can also turn on a heated steering wheel, or roll down all windows with just a single push. A lot of these features may seem convenient but they could make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in different ways based on the model and make of your car. You may be able to do it yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on a key fob, the microchip sends signals to the receiver in the car with which it is linked. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to drive.
Once the car is linked with a specific fob it will only receive signals from that device. In turn, other fobs won't work with the vehicle even though they have the same appearance. This ensures the security of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only work with vehicles that have original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed with out the need for a dealer.
