In order to work properly, these cars require that a transponder chip key be programmed into the vehicle by a professional locksmith or a car dealer/mechanic.
Professional locksmiths can perform various types of programming for car keys. Certain types are more complex and require specialized tools. These tools are not generally available to the public and are utilized only by professionals. This type of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other kinds of key programming can be carried out by anyone. They are typically done using the diagnostics port on the car, that can be accessed using an instrument for programming keys. This method can be done by a locksmith who is trained with the help of an online guide or an owner's manual.

The key might not function properly or not start the vehicle in any way. The reason for this is that the new key hasn't been programmed to the automobile's system - and this can be very costly. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It is also able to clone data from an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes and colors.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's a small plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is taken up by an antenna attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your car.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to prevent 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 in the plastic portion of the key, and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and will warn you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief might be able escape this security system by using a device that can detect the signal.
It is evident that a transponder is a great option. This is something that all vehicle owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to help locate the car or switch on the heated steering wheel. A lot of these additional features might seem useful, but they can also make it difficult for you to keep the track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. This communication is encrypted, which helps to stop others from stealing and replicating the signal.
There are many ways to program a key fob, based on the model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.
When you press a key fob's button it transmits an encoded code to the car's receiver that it is paired with. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car door. If the data doesn't match an chirping sound is heard and the car isn't permitted to function.
When a car is connected with a particular fob, it will only accept signals from the device that is associated with it. This means that other fobs won't work with the vehicle even if they appear similar. This is to safeguard the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that can only be found in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
