Newer models are equipped with computers that offer improved security against theft. To function correctly, these vehicles require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
Professional locksmiths are able to perform various types of programming for keys for cars. Some are complex and require specialized tools. These tools are usually not accessible to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other types of car key programming are a lot simpler and can be performed by the average person. They are accomplished using the onboard diagnosis port, which can be accessed by a specific tool for key-fob programming.

The reason is because the new key has not been programmed into the vehicle's system, and this could be quite expensive. This is why it's a great idea to always have two keys working for a modern car and to have the replacement key programmed when required.
Keyprogrammers are devices which can reprogram the transponder chip into an entirely new key fob or mechanical key. It also can clone data from an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional interface that works with an immobilizer system.
There are a number of different kinds of keyprogrammers on the market and they are available in all sizes and shapes. Some are inexpensive and others could cost thousands of dollars.

Transponder Chips
If your car was built in the past 20 years, then it has a transponder chip inside of it. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle can then 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 your vehicle to start it. 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 that are regular in shape like regular metal keys with an outer layer of plastic. The chip is inside the plastic part of these keys. There are a variety of cuts: a standard cut, 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 will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer in the car detects the signal as valid it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding siren. This feature is designed to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and committed thief could still be able to bypass this system by using a special device to take over the signal.
As you can see, there are quite a number of benefits to having transponder keys. All car owners should take this into consideration when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to aid in finding a car or switch on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are transmitted by a small antenna within the middle of the key. The communication is encrypted, which helps to stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your car. Certain cars let you do it yourself. However, click of modern models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.
When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it only accepts signals from the device. This means that other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
