Transponder Chips
If your car is made within the last 20 years, it is likely that it has a transponder chip inside of it. It's a small plastic piece on the back of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This prevents the vehicle from being started through hot-wiring, or by altering the key. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular metal keys but they have a plastic cap. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car recognizes the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter 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 blocks the signal.
car key programming near me can see that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car remotely, make chirping noises to aid in finding cars, or turn on the heated steering wheel. Many of these extra features may appear convenient but they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. These frequencies are sent via a small antenna that is located in the middle of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal.
There are a few different ways to program a key fob, based on the model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you hit the button on a key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compared the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's doors. If the information doesn't match the signals, the car will not be allowed to drive.
When a car is connected with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, despite the fact that they appear like. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
