Transponder Chips
If your car was manufactured within the last 20 years, it is likely that it has a transponder chip inside of it. It's a tiny piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from starting by hot-wiring or altering the key. The chip in the key also verifies that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys appear like regular keys made of metal but have a plastic cap. The chip is contained within the plastic part of the keys. There are several different cuts such as a standard cut laser cut (also known as 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 is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal may still be able to get around this system using a device that can intercept the signal.
You can see that a transponder is a great option. Every car owner should take this into consideration when they want to safeguard their investment and decrease theft risk.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding cars or switch on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna that is located in the center of the key. This communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
There are many ways to program a key fob depending on the make and model. programming car key is possible to do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is paired. The receiver compared the information with the permitted signals stored in the key fob and then it opens or closes the car's door. If the information does not match the signals, the car will not be allowed to run.
Once the car is paired with a particular fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they appear similar. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in a dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
