These cars require a transponder-chip integrated key to be programmed by a professional locksmith, car dealer or mechanic to function properly.
Professional locksmiths are able to perform a variety of different types of programming for keys to cars. Certain types are extremely complex and may require sophisticated tools. These tools are not generally accessible to the general public and are only used by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.

This is because the key has not yet been programmed into the car's system. This can be costly. car key programmers is why it's a good idea to have two working keys for modern vehicles and to have the replacement key programmed if needed.
Keyprogrammers are devices that can recode the transponder chip into a new mechanical or key fob key. It can also clone the information from an existing key and allow duplicate keys to be made. These are handheld devices that connect to a 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 user interface to work with an immobilizer system.

Transponder Chips
If your car was manufactured within the last 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of 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 prevents from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip in the car key ensures that the owner is the one who owns the vehicle. This can reduce car theft.
Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a regular standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer in the car is able to recognize the signal as correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the right one, it will keep the engine from running and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can take over the signal.
As you can see, there are quite a number of benefits to having transponder keys. This is something that all car owners should think about if they want to protect their investment and reduce the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding a car or turn on the heated steering wheel. A lot of these additional features may appear convenient but they could make it difficult for you to keep the keys to your car.
Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. You can sometimes do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.
When you hit the button on a key fob it transmits an informational code to the car's radio that it is paired with. The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to function.
When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, despite the fact that they appear identical. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place that has the experience to design the replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially those for older models with less sophisticated systems can be programmed with out the need for a dealership.
