Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. It's a tiny plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started through hot-wiring or manipulating. The chip inside the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are different types of cuts on these keys: a regular standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and siren. This feature is designed to deter people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still be able to escape this security system by using a device that can intercept the signal.
You can see that the transponder is an excellent option. This is something that all car owners should think about if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate a car in a parking lot Key fobs today can also activate the heated steering wheel or open all windows with a single push. These extra features can make it difficult for you to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located in the middle of the key. This communication is encrypted to prevent others from stealing or stealing the signal.
You can program a keyfob in various ways based on the model and brand of your car. Certain cars let you do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is linked. The receiver compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
After the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control of 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. It is because the only place with the knowledge to create an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
