Professional locksmiths can perform a variety of different types of programming for keys for cars. Some are very complex and require sophisticated tools. These tools are not accessible to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other types of programming car keys are a lot simpler and can be performed by anyone who is able to.

Key Programmers
Modern vehicles often require a key programming process to set up the car's system and allow the car to start. In some cases the key needs to be programmed by an auto locksmith or a dealer. The key may not function correctly or will not start the car at all. This is because the key hasn't yet been programmed into the car's system. This can be expensive. It's best to have two keys that work with your current car so you can program the replacement key whenever needed.

A keyprogrammer is a device which can reprogram the transponder chip in a new mechanical or key fob key. It is also able to clone information from an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.
There are a number of different kinds of keyprogrammers that are available and they are available in all shapes and sizes. Some are cheap while others are advanced and can cost thousands of dollars. Some are made for specific automobiles and provide advanced diagnostics of the car's electronic system.
If you want to program a new key to your vehicle, refer to the owner's manual to learn how to do it. Certain manufacturers employ proprietary software that only permits the dealership to create new keys. Other manufacturers make it easy for anyone to complete.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's a tiny plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
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. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This prevents the vehicle from starting by either hot-wiring or by tampering. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can help to reduce car theft.
Transponder keys appear like regular keys made of metal, but with caps made of plastic. The chip is located inside the plastic part of the keys. There are several different cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit inside the induction coil emits an electrical signal when the transponder is inserted into an ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and determined criminal could still be able to escape this security system by using a special device to take over the signal.
You can see that the transponder is a good option. Every car owner should take this into consideration if they wish to protect their investment and reduce theft risk.
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 turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it harder for you 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 through an antenna in the center of the key. The transmission is encrypted, which helps to stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip transmits a signal to the receiver in the car with which it is paired. The receiver compares this information with the 'allowed' signals on the fob and either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they look similar. This ensures the security of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it.
Most newer car dealerships will only work with cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
