In order to work properly, these cars require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
There are many types of car key programming that can be performed by professional locksmiths. Some are complex and require advanced tools. These tools are generally not available to the general public and are used only by professionals. This kind of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a lot of time.
Other types of programming for car keys are a lot simpler and can be done by anyone who is able to. They are accomplished using the onboard diagnostic port, which can be accessed with a special tool for key-fob programming. Locksmiths can execute this procedure with the help of an online guide as well as the owner's manual.

Key Programmers
Modern vehicles frequently require a key programming procedure to initialize the vehicle's system and allow the vehicle to begin. In some cases the key needs to be programmed by an auto locksmith or dealer. The key may not function properly or it may not even start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. It is best to have two keys that work for the modern automobile so that you can program the replacement key if required.
Keyprogrammers are devices which can reprogram the transponder chip in a new mechanical or key fob key. It is also able to copy the data from an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.
There are a variety of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors. Some are inexpensive while others could cost thousands of dollars.

These are cheaper than going to the dealership, but they're still not cheap. Make sure you investigate the seller prior to purchasing one - some are not reliable and could damage your vehicle.
Transponder Chips
If your car was built in 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 code unique to your car.
The chip sends out 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 ignition barrel of your car. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started through either hot-wiring or by tampering. The chip inside the key ensures that the owner is the person who owns the vehicle. This can reduce car theft.
Transponder keys look like normal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key, and there are different cuts that can be found on these keys: a regular cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be taken up 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 shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief may still be able to bypass this system by employing a device designed to detect the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all car owners should consider if are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot keys of today can also switch on a heated steering wheel, or open all windows with a single button press. A lot of these additional features might seem useful but they could make it difficult for you to keep track of your car keys.
programming keys fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in various ways based on the model and brand of your car. Certain cars let you do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or an additional one.
When you press a key fob's button it transmits a code to the car's receiver it is paired with. The receiver compared this information with the 'allowed' signals on the fob and either opens or closes the door. If the information doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a specific fob it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even if they appear similar. This safeguards the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
