Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's a small piece of plastic inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started by hot-wiring or altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys 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.
A circuit inside the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the right one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from trying to alter the vehicle, but it's not a 100% security measure. A determined and skilled thief could still bypass this system with a specially designed device that blocks the signal.
It is evident that the transponder is an excellent option. This is something that all car owners should think about if they are looking to safeguard their investment and decrease 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 vehicle from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. The frequencies are transmitted by a small antenna within the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.
There are many ways to program a key fob based on the model and make. It is possible to do this yourself, but most newer vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits an indication to the receiver in the car with which it is paired. The receiver compares this information to the signals that are allowed on the fob and either locks or opens the door. If the information doesn't match, a chirping sound is heard and the car isn't able to function.
Once the car is linked with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. Certain aftermarket fobs, typically those for older models with less sophisticated systems can be programmed with out the need for a dealer.
