Reprogramming the car key typically is the job of a locksmith or automotive specialist. They can make use of a specific software to program the new key by using your previous one.
The process involves reprogramming the blank chip inside the replacement key to match the current settings of your vehicle. Some manufacturers make it easy to do, while others require the assistance of a locksmith or dealer.
Self-Programming
As technology for cars has improved over time, the ignition keys have evolved as well. The days of simple mechanical keys that you could make at a hardware shop for less than $10 are long gone. Modern models come with computers that have improved anti-theft protection. To function properly, these cars require that a transponder chip key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
Professional locksmiths can perform various types of programming for keys for cars. Some are extremely complicated and may require sophisticated tools. These tools are not available to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.
Other types of programming for car keys are much easier and can be done by anyone who is able to. They are accomplished using the onboard diagnosis port, which can be accessed via a tool specifically designed for key fob programming. This method can be performed by a locksmith who is trained using an online guide or the car's owner manual.
Professional locksmiths can program a replacement or a brand new car key fob in a short time. This is the ideal option for vehicle owners as they can provide a complete range of services. They can also offer an affordable price and ensure that the replacement key will work correctly.

Key Programmers
Modern cars require a key-programming process to initialize their vehicle's systems and then start the vehicle. In some instances the key needs to be programmed by an auto locksmith or a dealer. The key might not function properly or it may not even start the car in any way. The reason is because the new key has not been programmed into the vehicle's system. This can be quite expensive. It's best to have two keys that work for the modern automobile so that you can program the replacement key if required.
A keyprogrammer is a tool that can recode the transponder chip into a new key fob or mechanical key. It is also able to clone data of an existing key which allows duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.
There are a number of different types of keyprogrammers available on the market and they come in all shapes and sizes. Some are inexpensive and others are advanced and could cost thousands of dollars. Certain models are specifically designed for automobiles and provide advanced diagnostics of the car's electronic system.
Refer to the owner's manual of your vehicle to learn how to program the key to your vehicle. Certain manufacturers employ proprietary technology that ensures the dealership is the sole entity able to create new keys. However, other manufacturers make it fairly easy for anyone to do it themselves.

Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is a little plastic thing in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
programing keys emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This is the reason why hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the key confirms that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip itself is housed in the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil emits signals when the transponder is inserted into an ignition barrel. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable 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 a few advantages to getting transponder keys. This is something that all vehicle owners should think about if they are looking to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding the car or switch on the heated steering wheel. A lot of these features might seem useful however they could make it more difficult to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in different ways based on the model and make of your car. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver 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 information doesn't match, the car will not be allowed to drive.
Once the car is connected to a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even though they look like. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
