Transponder Chips Transponder chips are likely to be found in cars manufactured in the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car. When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your specific vehicle. This is what prevents from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key confirms that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle. Regular transponder keys are designed like regular metal keys with a plastic top. The chip is inside the plastic part of these keys. There are various cuts: a standard cut, a Laser cut (also known as 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 will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin. If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and committed thief might be able bypass this system by using a device that can take over the signal. It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking space Key fobs today can also turn on a heated steering wheel, or roll down all windows with a single button click. These additional features could make it difficult to find your car keys. Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted through a small antenna located in the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal. You can program a keyfob in different ways based on the model and make of your vehicle. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one. When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver compares the information with the permitted signals stored in 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 able to function. When a car is connected with a specific fob it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they look the same. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle. Most newer car dealerships will only work with cars that have original fobs or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise 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 customers without the need for an authorized dealer.
