These cars require a transponder-chip integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
Professional locksmiths can carry out various types of programming for keys for cars. Some are extremely complicated and require sophisticated tools. These tools aren't usually accessible to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of car key programming are a lot simpler and can be performed by anyone who is able to.

It is recommended to have two keys that work for the modern automobile so that you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. car keys programming can clone data from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The 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 that is in the key is the right one for your specific vehicle.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip in the car key ensures that the owner is the person who owns the vehicle. This can reduce car theft.

Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip itself is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a regular standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still bypass this system with a specially designed device that blocks 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 consider if they are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding a car, or switch on the heated steering wheel. A lot of these features might seem useful, but they can also make it difficult for you to keep track of your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.
You can program a keyfob in different ways based on the model and brand of your car. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's doors. If the information does not match the signals, the car will not be allowed to drive.
After the car has been connected to a specific fob, it only accepts signals from the device. As a result, other fobs will not work with the vehicle even though they have the same appearance. This protects the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by customers without the need of dealers.
