Self-programming
As technology for cars has improved throughout the years, ignition keys have also evolved too. Gone are the days of simple mechanical keys that could be manufactured at an hardware store for less than $10. Newer models are equipped with computers that offer improved anti-theft protection. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic to function properly.
Professional locksmiths can perform various types of programming for keys to cars. Certain types are extremely complex and require sophisticated tools. These tools aren't usually available to the public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.
Other types of key programming can be performed by anyone. They are accomplished using the onboard diagnostic port, which can be accessed via a tool specifically designed for key fob programming. This procedure can be carried out by a locksmith who is trained using an online guide or the vehicle's owner manual.

Key Programmers
Modern automobiles require a key-programming procedure to start the vehicle's system and start the car. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key may not function properly or it may not even start the car in any way. This is because the key has not yet been programmed into the vehicle's system. This can be costly. It is best to have two keys that are compatible with your current car so you can program the replacement key whenever required.
A keyprogrammer is a tool which can reprogram the transponder chip on a new key fob or mechanical key. It is also able to copy the information from an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers. They also have a bidirectional interface that works with an immobilizer system.

They are less expensive than visiting a dealership, but still not expensive. Make sure you research the seller before purchasing one. Some aren't reliable and could harm your vehicle.
Transponder Chips
If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. This is a little plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the correct one for your specific vehicle.
This prevents the vehicle from being started by hot-wiring or manipulating. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble regular keys made of metal but have a plastic cap. The chip is housed inside the plastic portion of the key, and there are a few different types of cuts on these keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer on the car recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If car key fob programmer isn't able to recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and siren. This feature is intended to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined criminal might be able bypass this system by using a special device to intercept the signal.
It is evident that a transponder is a great option. All car owners must take this into consideration in order to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to help locate a car, or switch on the heated steering wheel. Many of these extra features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via an antenna in the center of the key. The signal is encrypted to stop others from stealing or modifying the signal.
There are a few different ways to program a key fob depending on the vehicle's model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one.
When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver then compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
After the car has been associated with a particular fob, it will only accept signals from the device. Other fobs will not work with the car, even though they appear like. This safeguards the integrity of the computer system of the car and prevents unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security expertise that can only be found in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
