There are a few different kinds of car key programming that can be performed by professional locksmiths. Certain are complicated and require specialized tools. These tools are usually not available to the general public and are only used by professionals.

These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder chip inside of it. This is a little piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is absorbed by a special antenna that is attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip in the key is the correct one for the car you have.
This is the reason why hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip is contained within the plastic part of the key and there are a few different kinds of cuts available on the keys: a cut laser cut (also called a sidewinder) or Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer inside the car recognizes the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still evade this system by using a specific device that intercepts the signal.
As you can see there are quite few advantages to getting a transponder key. This is something that all vehicle owners should consider if they want to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate the car or turn on the heated steering wheel. A lot of these features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs utilize 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. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in various ways based on the make and model of your car. You may be able to do it yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press a key fob's button it transmits a code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to run.
Once the car is paired with a specific fob it will only accept signals from the device that is associated with it. This means that other fobs will not work with the vehicle even if they have the same appearance. This ensures the security of the computer system of the car and blocks 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 that are offered by the manufacturer. automotive key programming is because the only place that has the expertise to prepare the replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially those from older models with less advanced systems can be programmed without the need for a dealer.
