Modern models come with computers that have improved security against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
There are a few different kinds of car key programming that can be accomplished by professional locksmiths. Some are complex and require advanced tools. These tools aren't generally accessible to the general public and are utilized only by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other types of key programming can be done by anyone. They are typically done using the onboard diagnostics port which can be accessed with a special key-fob-programming tool. This procedure can be carried out by a professional locksmith using an online guide or the car's owner manual.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then 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 determine if the transponder chip in the key is the correct one for your particular car.
This is what stops hot-wiring or tampering with the vehicle's ignition system to start it. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble regular metal keys but have caps made of plastic. The chip is inside the plastic part of the keys. There are various cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be received by the chip, causing it to send a signal back to the car. If the computer on the car detects this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding siren. This is designed to discourage people from attempting to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief could still evade this system using a special device that detects the signal.
It is evident that a transponder is a great option. All car owners should consider this if they wish to protect their investment and reduce theft risk.
Key Fobs

car key programming G28CarKeys can be programmed in various ways based on the model and make of your car. Certain models allow you to do this yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or an additional one.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is linked with a specific fob it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
