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 kinds of car key programming that can be done by locksmiths who are professionals. Certain types are more complex and require advanced tools. These tools aren't usually available to the public and are utilized only by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.

Key Programmers
Modern automobiles require a key-programming method to initialize their vehicle's systems and then start the vehicle. In some instances, the key will need to be programmed by an auto locksmith or a dealer. The key might not function properly or it may not even start the vehicle at all. The reason is because the new key has not been programmed into the vehicle's system - and this can be very costly. It is best to have two keys that work for the modern automobile so that you can program the replacement key when needed.
A keyprogrammer is a tool that can recode the transponder chip in a new mechanical or key fob key. It is also able to copy information from an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers, and they also have a bidirectional interface for working with the immobilizer system.
There are a myriad of types of keyprogrammers on the market. They are available in a variety of sizes, shapes, and colors. Some are inexpensive and others may cost thousands of dollars. Certain models are specifically designed for automobiles and offer advanced diagnostics of the vehicle's electronic system.
If you're looking to program a new key to your vehicle, check the owner's manual to find out how to do it. Certain manufacturers have proprietary technology that guarantees that the dealership is the sole entity able to create new keys. However, other manufacturers make it fairly simple for anyone to do it themselves.
If you are not able to program the new key yourself, then you can ask your dealer to do it, however it will be very costly. You can also buy a keyprogrammer on the internet. They are less expensive than going to a dealership but they aren't cheap. Make sure you look up the seller before buying one - some are not reliable and could damage your car.
Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder inside of it. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When activated by an electro-magnetic field the chip emits a low level signal. This signal then gets taken up by the antenna that is attached to the ignition barrel of your car. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to get it started. The chip in the key also proves that you are the legal owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys and have a plastic top. The chip is contained within the plastic part of the keys. There are various cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil emits a signal when the transponder is put into an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car detects this signal as the correct one, it will turn off the vehicle's immobilizer 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 running and will notify you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined criminal might be able bypass this system by using a special device to take over the signal.
As you can see there are quite number of benefits to having transponder keys. Every car owner should take this into consideration in order to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding a car or turn on the heated steering wheel. These extra features could make it difficult to locate your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted through a small antenna located in the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are several ways to program a key fob, based on your vehicle's make and model. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one.
When you press a key fob's button the microchip inside sends an encoded 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 opens or locks the door. If the information does not match the signals, the car will not be allowed to run.
After the car has been paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they appear identical. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
Most newer car dealers will only work on a car 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 from older models with less advanced systems can be programmed without the need for a dealership.
