Transponder Chips
If your car was manufactured in the past 20 years, then it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is fitted 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 vehicle.
This prevents the vehicle from starting by hot-wiring or tampering. The chip in the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble regular keys made of metal, but with a plastic cap. The chip itself is housed inside the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and siren. This system is designed to deter people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still evade this system using a special device that detects the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if are looking to safeguard their investment and decrease the chance of theft.

These additional features can make it difficult for you to locate your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna that is located in the center of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are several ways to program a key fob depending on your vehicle's model and make. Certain cars let you do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the car that it is paired. The receiver compares the information with the permitted signals stored in the key fob and then opens or locks the car's door. If the data does not match the signals, the car will not be allowed to drive.
Once the car is linked with a specific fob, it will only receive signals from that device. Other fobs will not work with the car, even if they look similar. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only work with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills which can only be obtained in the dealer's service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed without the need for a dealership.
