Transponder Chips
If your car was built within the past 20 years, chances are it has a transponder chip inside of it. This is a little plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets taken up by the antenna that is attached to the ignition barrel of your car. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is inside the plastic portion of these keys. There are a variety of cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and an alarm. This is designed to discourage people from attempting to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all car owners should consider if they want to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding the car in a parking space, today's key fobs can also switch on a heated steering wheel, or roll down all windows with just a single push. Many of these extra features may seem convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
You can program a keyfob in various ways based on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer 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 in the vehicle with which it is paired. The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a specific fob, it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle, even though they appear similar. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
The majority of newer dealerships will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. This 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 dealers.
