The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
There are many types of car key programming that can be accomplished by professional locksmiths. Some are very complex and may require sophisticated tools. These tools are generally not accessible to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.

Key Programmers
Modern vehicles typically require a key programming process to start the system of the vehicle and allow the vehicle to start. In some cases the key will have to be programmed by an auto locksmith or dealer. The key may not work correctly or will not start the car in any way. This is because the key has not yet been programmed into the car's system. This could be costly. This is why it's a good idea to always have two keys that work for a modern automobile and have the replacement key programmed if needed.
A keyprogrammer is a device that can recode the transponder chip in the form of a new key fob or mechanical key. It is also able to clone data of an existing key which allows duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers on the market. They are available in a variety of sizes, shapes, and colors. Some are inexpensive, while others can cost thousands of dollar. Certain models are specifically designed for certain types of vehicles and provide advanced diagnostics for your electronic systems of the car.
If you're looking to program a new key to your vehicle, consult the owner's manual for instructions on how to do it. Certain manufacturers employ proprietary software that only allows the dealership to create new keys. Other manufacturers make it easy for anyone to do.
If you are unable to program the new key yourself and you are unable to do it, then have your dealer do it, but it will be very costly. You can also buy an online keyprogrammer. They're less expensive than going to the dealership, but they're still not cheap. Before you purchase one do some research on the seller. Some are not reliable and may damage your vehicle.
Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's a small piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is attached to the barrel that controls your ignition in your car. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started through hot-wiring or tampering. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Transponder keys look like normal keys but have a plastic cap. The chip is housed within the plastic part of the key and there are a few different types of cuts on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and determined criminal could still be able to bypass this system by using a device that can intercept the signal.
As you can see there are quite number of benefits to having transponder keys. Every car owner should consider this if they wish to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space keys of today can also turn on a heated steering wheel or open all windows with a single click. Many of these extra features might seem useful but they could make it difficult for you to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press the button on your key fob it transmits an informational code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the data does not match, the car will not be allowed to operate.
Once the car has been paired with a specific fob, it only accepts signals from the device. In turn, other fobs will not work with the vehicle even though they look the same. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
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 only place that has the knowledge to create an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by consumers without the need of a dealership.
