These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, mechanic or dealer in order to function properly.
Professional locksmiths can perform various kinds of programming for car keys. Certain types are extremely complex and require sophisticated tools. These tools are not generally available to the public and are used only by professionals. This type of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.

Key Programmers
Modern vehicles require a key-programming method to start the vehicle's system and then start the vehicle. In some instances the key needs to be programmed by an auto locksmith or dealer. The key may not function correctly or will not start the car at all. This is because the key hasn't yet been programmed into the vehicle's system. This could be costly. It's best to have two keys that work with your current car so you can program the replacement key if needed.
A keyprogrammer is a device which can reprogram the transponder chip into an entirely new key fob or mechanical key. It is also able to copy information from an existing key to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are many various kinds of keyprogrammers that are available and they come in all sizes and shapes. Some keyprogrammers are cheap and others could cost thousands of dollars.

Check out the owner's manual to learn how to program the key to your vehicle. Certain manufacturers have proprietary technology that ensures the dealership is the sole entity that can create new keys, but other manufacturers make it fairly simple for anyone to do it themselves.

Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. It's the tiny plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your 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 attached to the barrel that controls your ignition in your vehicle. This allows the car's computer system to determine if the transponder chip that is in the key is the correct one for the car you have.
This is what stops from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the key also proves that you are the legal owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is contained within the plastic part of the key and there are a few different cuts that can be found on these keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as being the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the car does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal.
You can see that the transponder is an excellent option. Every car owner should consider this if they wish to protect their investment and minimize theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the car from a distance, make chirping sounds to help locate a car or turn on the heated steering wheel. A lot of these features might seem useful, but they can also make it more difficult to keep the track of your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted by a small antenna located in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your car. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver that it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is linked with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look similar. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealers 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 knowledge that is only available in the dealer's service department. Some fobs from the aftermarket, especially those from older models with less advanced systems, can be programmed without the need for a dealer.
