Transponder Chips
If your car was manufactured in the last 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic piece inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are several different cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from attempting to alter the vehicle, however it is not a foolproof security measure. A skilled and determined criminal might be able get around this system employing a device designed to take over the signal.
You can see that the transponder is a good option. All car owners must take this into consideration if they wish to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding cars or turn on the heated steering wheel. These additional features could make it difficult to locate your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted by an antenna in the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.
Keyfobs can be programmed in various ways based on the model and brand of your car. Certain models allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press the button on your key fob it transmits an encoded code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to function.
After the car has been connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they appear identical. This safeguards the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements sold by the manufacturer. It is because the only place with the expertise to prepare an appropriate replacement fob is a dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems, can be programmed without the need for a dealer.
