Transponder Chips
Transponder chips are likely to be found in cars manufactured in the last 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to start it. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble normal keys, but with caps made of plastic. The chip is contained within the plastic portion of the keys. There are various cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit inside the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This is designed to deter people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal could still be able to bypass this system by using a device that can detect the signal.
You can see that a transponder is a great option. Every car owner should consider this if they wish to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding a car in a parking lot keys of today can also turn on the heated steering wheel or roll down all windows with a single button push. These extra features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via an antenna in the center of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are many ways to program a key fob, based on your vehicle's make and model. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver that it is paired with. The receiver then compares the data with the permitted signals stored in the key fob, and then it opens or closes the car's doors. If the data does not match the fob's information, the car won't be allowed to operate.
After the car has been associated with a particular fob, it can only receive signals from the device. Other fobs won't work with the car, even though they appear like. This protects the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological 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 advanced systems can be programmed without the need for a dealer.
