Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car detects the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will notify you via flashing lights and siren. This feature is intended to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and committed thief could still be able to bypass this system by using a special device to intercept the signal.
You can see that the transponder is a good option. This is something that all vehicle 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 remotely or making sound chirps to help locate a car in a parking lot Key fobs today can also activate a heated steering wheel or roll down all of the windows with a single push. These extra features can make it difficult for you to find your car keys.
Key fobs use radio frequencies to connect with one another and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are several ways to program a key fob depending on your vehicle's make and model. You can sometimes do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits an indication to the receiver in the car with which it is linked. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.
Once the car is associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even if they appear identical. This protects the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only work with cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
