Transponder Chips
If your car was manufactured within the last 20 years, then it has a transponder inside of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip in the car key verifies that the owner is the one who owns the vehicle. This can reduce car theft.
Transponder keys appear like normal keys, but with caps made of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
A circuit inside the induction coil emits signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined criminal may still be able to bypass this system by using a device that can take over the signal.
As you can see there are quite a number of advantages to having transponder keys. Every car owner should consider this when 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 the car in a parking space, today's key fobs can also switch on a heated steering wheel or roll down all of the windows with a single button push. A lot of these features may appear convenient however they could make it difficult for you to keep the track of your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
There are several ways to program a key fob based on the make and model. It is possible to do this yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the vehicle that it is paired. The receiver then compares the data 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 fob's information, the car won't be allowed to drive.
After the car has been paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look like. This ensures the security of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the expertise to prepare the replacement fob is a dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems, can be programmed without the need for a dealer.
