Transponder Chips
Transponder chips can be found in cars manufactured in the last 20 years. This is a little plastic thing inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through hot-wiring, or by manipulating. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular metal keys, but with a plastic cap. The chip is housed in the plastic portion of the key, and there are a few different cuts that can be found on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car detects the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A determined and skilled thief could still evade this system by using a specific device that intercepts the signal.
It is evident that the transponder is an excellent option. automotive key programming should consider this if they wish to protect their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking lot keys of today can also turn on a heated steering wheel or roll down all windows with a single button press. These additional features can make it difficult to locate your car keys.
Key fobs communicate with one with the car via radio frequencies which are transmitted by a small antenna located in the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on the make and model. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals on the fob and either opens or closes 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.
Once the car is paired with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear like. This is to safeguard the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
