Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can create tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to stop theft of cars. These are tiny computer microchips which emit radio signals of low-level. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proved to be an incredible success in preventing auto theft. It also saves many car owners a significant amount of money as they don't need to replace their vehicles.
The principle of the transponder system is to make it difficult for thieves to get into your car without the right key. In the past, car thieves would simply push the ignition switch of your car into the "on" position with a flat screwdriver or even hot-wire the car to bypass the system entirely. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you place the transponder key into the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will then recognise the key as valid and allow fuel flow, power the starter or begin the engine.
Some vehicles only recognize certain type of transponder chips, depending on the manufacturer. This is why it's essential to ensure that your locksmith in the automotive industry has the appropriate equipment to program your car's key and fobs correctly.
A reliable locksmith for cars will have a multi-vehicle programming device which can be used with different models and brands of cars.

They are not as common, but there are specialised automotive key programming tools that can only work on a specific brand of vehicle. The top automotive locksmiths are equipped to work on any vehicle. Be sure to choose an established company that has this kind of equipment.
Key FOBs

Some fobs have additional functions that can be controlled by the press of a button for example, the "smart" key fob that lets you bring your car to parking spots that are tight similar to a Tesla or Genesis GV60.

The cost of a car key fob varies depending on the type and model of key, but is typically between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.

This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming tool can be a simple handheld device or a more expensive one that can perform a wide range of things beyond just key programming (like reading and cloning the eeprom files in the ECU).

EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional who has a lot of experience working with these kinds of systems.
Locksmiths can program keys quickly using onboard programming. When everything is done correctly, it can take as little as one minute. If the key isn't in the right condition or the procedure isn't strictly followed, it could take up to a half hour.
There are many key programmer scanners that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they can be used with a variety of vehicles. However, neither will be able to program every vehicle on the market. Furthermore, these systems are expensive. It's best to purchase one that will receive regular updates from the manufacturer whenever new technologies are developed. If not, your computer will soon become obsolete.
