Transponder Chips
If your car is made within the past 20 years, then it has a transponder inside of it. This is a little piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for the car you have.
This is what stops hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This helps to prevent car theft.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is inside the plastic part of these keys. There are a variety of cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which sends a signal to the vehicle. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and a siren. This feature is intended to deter people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still evade this system using a special device that intercepts the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should consider if they are looking to safeguard their investment and minimize the risk 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 the car, or switch on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob, the microchip sends signals to the receiver inside the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car's doors. If the information doesn't match the signals, 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. In turn, other fobs will not work with the vehicle even if they have the same appearance. This protects the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control of the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. It is because the only place that has the experience to design a replacement fob is in a dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
