Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and make the process could be as simple as using an extra key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian automakers share their programming protocol with auto tool manufacturers, so they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio waves. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a huge deal of money since they don't have to buy new vehicles.
The principle behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, car thieves would force the ignition switch of your car into the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system entirely. Transponder chips have drastically reduced these types of thefts.
When you place the transponder key into the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will recognize that the key is genuine and allow fuel to flow, turn up the starter or begin it.
Depending on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that is compatible with different car manufacturers and models. This is a far cheaper alternative than buying individual tools for each brand of vehicle. These aren't as popular but there are automotive key programmers that can only be used on a specific type of vehicle. The top automotive locksmiths are equipped to work on any vehicle. Make sure you choose a reliable company that is equipped with this kind of equipment.
Key FOBs

It is also possible to press buttons to activate features such as trunk releases, door locks or fuel flap controls. Some fobs can be controlled with the press of buttons. For instance an "smart key" which allows you to summon your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60.

A professional is better equipped to connect your computer to the vehicle via the OBD port located under the steering wheel.
The majority of key fobs today have security features that make it difficult for hackers to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators that generate a new unlock code every time you press the button. This prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.
In certain instances you can purchase the replacement keyfob at a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who create the tools used by locksmiths for programming their customers' keys.
Although some key fobs from the aftermarket are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them because they are likely to function poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they function properly and are less prone to issues like interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.

This includes the labor to program the key fob and the costs for any required replacement parts.
