Transponder Chips If your car is made in the last 20 years, it is likely that it contains a transponder chip within of it. It's a tiny plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car. This is the reason why from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer onboard the car detects the signal as valid it will turn off the car immobilizer so that the engine can start. If the car doesn't recognize the transponder as the correct signal, it will not start the engine, and will alert you with flashing lights and a siren. This system is designed to deter people from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief can still get around this system using a special device that detects the signal. As you can see, there are quite a number of advantages to having transponder keys. All car owners should take this into consideration when they want to safeguard their investment and reduce the chance of theft. Key Fobs Key fobs today can offer more than locking and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding the car or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys. Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located within the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal. You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or an additional one. When you hit the button on a key fob, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver then compares the data with the 'allowed signals' stored on the key fob and then opens or locks the car's door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function. Once the car has been connected to a specific fob, it only accepts signals from that device. This means that 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 prevent unauthorized key fobs from gaining control of the vehicle. Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that is only available in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
