Transponder Chips
Transponder chips are likely be found in cars that were manufactured in the last 20 years. This is a little piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip emits a low-level 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 will then confirm that the key's transponder chip is the correct one for your car.
automotive key programming stops the vehicle from being started by hot-wiring or altering the key. The chip inside the car key ensures that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is contained inside the plastic portion of the key and there are different types of cuts on these keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car is able to recognize the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as being the right one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and committed thief could still be able to get around this system using a device that can detect the signal.
As you can see there are quite number of advantages to having a transponder key. Every car owner must take this into consideration when they want to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking lot, today's key fobs can also turn on a heated steering wheel, or open all windows with a single button click. A lot of these additional features may seem convenient but they could make it harder for you to keep track of your car keys.
Key fobs communicate with one with the car via radio frequencies that are transmitted by an antenna in the center of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob based on the make and model. You may be able to do it yourself, but the majority of newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' that are 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 operate.
Once the car is paired with a particular fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they look similar. This protects the integrity of the computer system of the car and prevents unauthorized key fobs gaining control over it.
The majority of newer dealerships will only accept cars with original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models that have less sophisticated systems can be programmed with out the need for a dealer.
