Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the last 20 years. This is a little plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your vehicle.
This is what stops from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the key also proves that you are the legal owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is inside the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start your vehicle remotely, make chirping noises to help locate the car or turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it difficult for you to keep the keys to your car.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted by a small antenna located in the center of the key. The communication is encrypted, which helps keep others from stealing and replicating the signal.
There are several ways to program a key fob depending on your vehicle's make and model. Some cars allow you to do this by yourself. However, most 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 transmits a signal to the receiver inside the car that it is paired. The receiver compares this information to the 'allowed' signals stored on the fob and either locks or opens the door. If the data does not match the signals, the car will not be allowed to drive.
When a car is connected with a specific fob it will only receive signals from the device that is associated with it. As a result, other fobs won't work with the vehicle, even though they have the same appearance. This ensures the security of the computer system of the car and prevents unauthorized key fobs gaining control of it.
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. It is because the only place with the experience to design the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed with out the need for a dealer.
