Transponder Chips
If your car is made within the last 20 years, chances are it has a transponder inside of it. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the key also confirms that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys resemble normal keys, but with caps made of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. 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 valid it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A determined and skilled thief could still evade this system by using a specific device that intercepts the signal.
As you can see there are quite number of advantages to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate a car in a parking space Key fobs today can also switch on a heated steering wheel, or roll down all windows with just a single press. These extra features can make it difficult for you to locate your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the vehicle with which it is paired. The receiver compares this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.
After the car has been paired with a specific fob, it can only receive signals from that device. This means that other fobs will not work with the vehicle, even though they look the same. This safeguards the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that is only available in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
