The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer in order to function properly.
There are many types of car keys programming that can be done by professional locksmiths. Some are very complex and may require advanced tools. These tools aren't usually available to the public and are utilized only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.
Other kinds of key programming can be performed by anyone. They are accomplished using the onboard diagnosis port, which can be accessed with a special tool for key fob programming. A locksmith can perform this method with the assistance of an online guide and the owner's manual.

Key Programmers
Modern cars require a key-programming process to start the vehicle's system and then start the vehicle. In some instances the key will have to be programmed by an auto locksmith or dealer. This is because the key might not function correctly, or it will not start the vehicle at all. This is because the new key hasn't been programmed into the vehicle's system - and this can be quite costly. It is best to have two keys that are compatible for your modern car so you can program the replacement key when required.
Keyprogrammers are devices that can recode the transponder chip in an entirely new key fob or mechanical key. It is also able to clone data of an existing key and allow duplicate keys to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers available that are available, and they come in all sizes and shapes.

If you're not able to program a new key yourself or ask the dealership to do it for you, however it will cost a lot. Another option is to buy a keyprogrammer online. They are less expensive than going to a dealership, but still not cheap. Before buying one, do some research on the seller. Some aren't reliable and could cause damage to your vehicle.
Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder inside of it. It's a tiny plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. The signal is absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for the car you have.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys and have a plastic top. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be received by the chip, causing it to transmit a signal back to the car. If the car's computer recognizes this signal as being the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and determined criminal might be able bypass this system by employing a device designed to take over the signal.
As you can see there are quite number of advantages to having a transponder key. All car owners should consider this in order to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the car 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 the keys to your car.
Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted through a small antenna located inside the middle of the key. The communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
There are a few different ways to program a key fob depending on the make and model. It is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip sends an indication to the receiver in the car with which it is linked. The receiver compares the information with the permitted signals stored in the key fob, and then it opens or closes the car door. If the information doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob, it will only receive signals from that specific device. In turn, other fobs will not work with the vehicle, even though they appear similar. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is a dealer's 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 dealer.
