Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is a little piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna that is attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This stops the vehicle from being started by hot-wiring or manipulating. The chip in the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of these keys. There are several different cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit within the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and alert you with flashing lights and a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still be able to get around this system using a special device to detect the signal.
You can see that the transponder is an excellent option. Every car owner should take this into consideration in order to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding the car or switch on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna that is located in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on the model and make. You can sometimes do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits a signal to the receiver in the car with which it is linked. The receiver compared this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
When a car is connected with a specific fob, it will only accept signals from the device that is associated with it. In turn, other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
