Transponder Chips
Transponder chips are likely be found in cars manufactured within the last 20 years. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. This signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your vehicle.
This is what stops from modifying or hot-wiring the vehicle's ignition system to get it started. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is inside the plastic part of the keys. There are a variety of cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car does not recognize the transponder signal as being the proper one, it will stop 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 an unbreakable security measure. A skilled and determined thief could still bypass this system using a special device that blocks the signal.
It is evident that a transponder is a great option. This is something that all vehicle owners should think about if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking space, today's key fobs can also turn on the heated steering wheel or roll down all windows with just a single click. These extra features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are sent by a small antenna inside the middle of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the model and make of your car. You may be able to do it yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or a second 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 linked. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
After the car has been associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from programmable car keys taking control of the vehicle.
Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems, can be programmed without the need for a dealership.
