Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from starting by either hot-wiring or by manipulating. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted 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 then transmits a signal the vehicle. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still be able to escape this security system by employing a device designed to intercept the signal.
As you can see there are quite number of benefits to having transponder keys. Every car owner must take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate cars, or turn on the heated steering wheel. Many of these extra features may seem convenient however they could make it harder for you to keep the track of your car keys.
Key fobs communicate with each other and the car using radio frequencies which are transmitted through a small antenna located in the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is paired with. The receiver compares the information with the permitted signals stored in the key fob, and then locks or opens the car's doors. If the information does not match the signals, the car will not be allowed to run.
Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they look similar. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only work with cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need of a dealership.
