Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it contains a transponder chip within of it. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also proves that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip is housed inside the plastic portion of the key, and there are different types of cuts on these keys: a regular cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the right one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief may still be able to escape this security system by using a device that can intercept the signal.
You can see that the transponder is a good option. Every car owner must take this into consideration when they want to safeguard their investment and minimize theft risk.
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 space Key fobs today can also turn on the heated steering wheel or open all windows with just a single click. A lot of these additional features may seem convenient but they could make it harder for you to keep track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in a variety of ways depending on the make and model of your car. It is possible to do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is paired. The receiver compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to function.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear similar. This safeguards the integrity of the computer system in the car and prevents unauthorized key fobs gaining control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models with less advanced systems can be programmed without the need for a dealership.
