Transponder Chips
Transponder chips are likely be found in cars manufactured within the past 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the right one for the car you have.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the car's computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and siren. This feature is intended to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still evade this system using a special device that detects the signal.
As you can see there are quite number of advantages to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking lot, today's key fobs can also switch on a heated steering wheel or roll down all windows with a single button push. A lot of these features may appear convenient however they could make it more difficult to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna that is located in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob, based on the model and make. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends a signal to the receiver inside the car that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is linked 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 if they look identical. This safeguards the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially those from older models that have less advanced systems, can be programmed without the need for a dealer.
