The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic in order to function properly.
There are many kinds of car key programming that can be done by professional locksmiths. Certain are complicated and require specialized tools. These tools are not generally available to the public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.
Other types of programming for car keys are much simpler and can be accomplished by anyone who is able to. These are done with the onboard diagnostic port, which can be accessed by a specific tool for key fob programming.

The key may not function properly or it may not even start the car in any way. This is because the new key has not been programmed to the automobile's system - and this can be quite expensive. This is why it's a great idea to have two keys working for modern vehicles, so you can get the replacement key programmed when necessary.
A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the data of 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 as well as a bidirectional interface for working with the immobilizer system.
There are a number of various kinds of keyprogrammers on the market and they are available in a variety of sizes and shapes.

They are cheaper than going to a dealership but they aren't expensive. Be sure to investigate the seller prior to purchasing one - some are not reliable and could harm your car.
Transponder Chips
If your car was built in the last 20 years, chances are it contains a transponder chip within of it. It's a tiny plastic thing in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for your particular car.
This is what prevents hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular metal keys but they have a plastic cap. The chip is contained within the plastic part of these keys. There are several different cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will notify 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 a foolproof measure of security. A skilled and committed thief may still be able to get around this system using a special device to intercept the signal.
It is evident that the transponder is an excellent option. This is something that all car owners should think about if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding a car or turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it difficult for you to keep the keys to your car.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are several ways to program a key fob based on the model and make. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob it transmits an encoded code to the car's receiver that it is paired with. The receiver compared the information with the permitted signals stored in the key fob, and then opens or locks the car door. If the information doesn't match the signals, the car will not be allowed to operate.
Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
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 the process of creating an appropriate replacement fob requires technical and security skills that can only be found in the dealer's service department. Certain aftermarket fobs, typically ones for older models that have less advanced systems can be programmed without the need for a dealership.
