Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can design software or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are found in a variety of newer vehicles to guard against theft of vehicles. These are microchips in the form of computers that emit low-level radio signals. The microchips are equipped with an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a huge amount of money by not having to replace their vehicles.
The fundamental idea behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would simply push your ignition switch to the "on" position using a flat screwdriver or even make use of hot-wires to bypass the system altogether. Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder keys in the ignition the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will detect that the key is genuine and allow the fuel to flow, then power up the starter or begin it.
Some vehicles only recognize certain type of transponder chip depending on the manufacturer. Therefore, it is essential that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that is compatible with different car manufacturers and models.

Make sure you choose a reliable company that is equipped with this kind of equipment.
Key FOBs

You can also use the buttons to trigger features such as trunk locks, door locks or controls for the fuel flap. Certain fobs can be controlled with the press of buttons. For instance the "smart key" that allows you summon your car to parking spaces, such as a Tesla or Genesis GV60.

These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase the replacement keyfob at an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that make the tools used by locksmiths for programming their customer's keys.

Instead, they recommend purchasing fobs that are specifically made for your vehicle so that you can be certain they'll work properly and are less susceptible to issues such as interfering or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools

One of the key components of this technology is a transponder chip that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs come with built-in security features that stop hot-wiring (like in a movie) and the car will not start if you don't have the proper key.

This is why they are usually handled by experienced, professional auto locksmiths. car key programming of a key fob will vary depending on the car model and the type of key, but they typically run between $85 to $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.

This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter an programming mode. Key programming tools can either be an inexpensive handheld device or a fancy one that can perform many things beyond key programming (like reading and cloning Eeprom files within the ECU).
