Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder inside of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys resemble regular keys made of metal, but with a plastic cap. The chip itself is housed within the plastic part of the key, and there are different types of cuts on these keys: a regular cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits an electrical signal when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will alert you with flashing lights and a siren. This feature is designed to discourage people from attempting to alter the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still evade this system by using a specific device that intercepts the signal.

A lot of these features may appear convenient but they could make it harder for you to keep the keys to your car.
Key fobs communicate with each other and the car using radio frequencies which are transmitted through an antenna in the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
There are automotive key programming near me to program a key fob depending on the vehicle's model and make. It is possible to do this yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compared this information with the signals that are allowed on the fob and either locks or opens the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
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, even though they look like. 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.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills that can only be found in the dealer service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed with out the need for a dealer.
