Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the car's make and model, the process can be as easy as programming onboard using an extra working key or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool makers in order to create hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are in a variety of newer vehicles to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a good amount of money by not having to purchase new cars.
The basic concept behind the transponder system is to make it difficult for thieves to open the doors of your car without the right key.

Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it transmits a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip in the key. The computer onboard of the car will then recognize the key as being valid and will allow fuel flow, power the starter or start the engine.

It is also possible to press buttons to trigger features such as door locks, trunk releases or control of the fuel flap. Some fobs also have additional functions that can be controlled with the button presses like a "smart" key fob that lets you summon your car into tight parking spots similar to a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the help of a user manual but you'll usually require an automotive locksmith to have a new one programmed if yours stops functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port located under the steering wheel.
The majority of key fobs today include security features that make it difficult for criminals to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators which generate a new unlock code each time you press the button. This prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.
In some cases, you can buy a replacement keyfob from an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your car. This is because most of the major US and Asian automobile manufacturers share their key fob programming protocols with third-party companies that make the tools that locksmiths use to program keys for their customers.

The software prevents unauthorised access by only allowing keys that have been programmed for a specific vehicle to function. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car in order for it to work.

This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a high-end one that can do a wide range of things beyond 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 complex and requires a thorough understanding of electronic systems. It is best to leave it to a professional with knowledge of these systems.
Locksmiths can program keys quickly using onboard programming. If everything is done properly it can take as little as one minute. If the key isn't in the right condition or the procedure isn't followed exactly, the process could take as long as a half hour.
