Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's the small plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your specific vehicle.
This is what stops from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip itself is housed in the plastic portion of the key, and there are different types of cuts on these keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and skilled criminal could still evade this system with a specially designed device that blocks the signal.
As you can see there are quite a few advantages to getting a transponder key. This is something that all vehicle owners should think about if they want to safeguard their investment and minimize the chance of theft.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the car with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the data does not match, the car will not be allowed to drive.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they look identical. automotive key programming protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer.
