Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the last 20 years. 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 it is activated by an electromagnetic field the chip emits a low level signal. This signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the vehicle's computer system to verify that the transponder chip in the key is the right one for your particular car.
This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is inside the plastic part of the keys. There are various cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
The circuit in the induction coil emits a signal when the transponder is put into an ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief could still evade this system with a specially designed device that intercepts the signal.
As you can see there are quite number of advantages to having a transponder key. This is something that all car owners should think about if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find the car in a parking lot Key fobs today can also turn on a heated steering wheel, or open all windows with a single click. These additional features could make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna inside the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain models allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver compares the information with the permitted signals stored on the key fob and then locks or opens the car's door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, despite the fact that they look identical. This protects the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer's service department. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems can be programmed without the need for a dealership.
