Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This prevents the vehicle from being started through hot-wiring or manipulating. The chip in the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys resemble normal keys but they have caps made of plastic. The chip is inside the plastic part of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and a 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 then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from attempting to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and determined criminal could still be able to escape this security system by using a special device to intercept the signal.
As you can see, there are quite a number of advantages to having a transponder key. All car owners should consider this when they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding a car or switch on the heated steering wheel. A lot of these features may appear convenient, but they can also make it more difficult to keep track of your car keys.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through a small antenna located in the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
There are a few different ways to program a key fob based on the vehicle's make and model. Certain models allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
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 this information with the 'allowed' signals stored in the fob and then either opens or locks the door. If the data does not match the signals, the car will not be allowed to operate.
Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain 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 supplied 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 service department. Certain aftermarket fobs, typically those from older models with less advanced systems can be programmed with out the need for a dealer.
