Transponder Chips
If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. It's the small plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for the car you have.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also proves that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular keys made of metal but they have caps made of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the 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 back to the car. If the car's computer detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car isn't able to cut and program car keys recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal could still be able to get around this system using a device that can detect the signal.
As you can see there are quite a few advantages to getting transponder keys. All car owners should consider this if they wish to protect their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking space Key fobs today can also switch on the heated steering wheel or roll down all windows with a single press. A lot of these features may appear convenient, but they can also make it harder for you to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through an antenna in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match, the car will not be allowed to drive.
Once the car is paired with a specific fob it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need of dealers.
