The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer for proper operation.
Professional locksmiths are able to perform a variety of different types of programming for keys to cars. Some are complex and require specialized tools. These tools aren't usually accessible to the general public and are utilized only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of car key programming are much simpler and can be done by the average person. These are done using the onboard diagnosis port, which can be accessed via a tool specifically designed for key-fob programming.

The key may not work correctly or will not start the vehicle at all. The reason is because the new key hasn't been programmed to the car's system, and this could be quite costly. This is why it's a good idea to always have two working keys for modern vehicles and to have the replacement key programmed when needed.
A keyprogrammer can reprogram the transponder chip of a new mechanical key or key fob. It is also able to clone data from an existing key which allows duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the last 20 years. It's a tiny plastic thing inside the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key ensures that the owner is the one who owns the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are car remote key programming : a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and committed thief might be able get around this system employing a device designed to take over the signal.
As you can see there are quite a few advantages to getting a transponder key. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate the car in a parking lot Key fobs today can also activate a heated steering wheel or roll down all windows with a single button click. These extra features could make it difficult to find your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. You can sometimes do this yourself, however most modern vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to operate.
Once the car is paired with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even though they look like. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered 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. Some fobs from the aftermarket, especially those for older models that have less advanced systems can be programmed without the need for a dealership.
