Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using an extra working key or as complex 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 software and hardware for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips are equipped with a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has proven to be a huge success in preventing theft of cars. This technology has also helped car owners save a good deal of money by not having to purchase new cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to start your car without the proper key. In the past, car thieves would simply force the ignition switch of your car into the "on" position using an ordinary screwdriver or use hot wires to disable the system completely. These types of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits a signal that is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will then detect that the key is legitimate and allow fuel to flow, turn up the starter, or even begin it.

They also have buttons you can press to activate features such as door locks, trunk release or control of the fuel flap. Some fobs can be controlled with the press of buttons. For instance, a "smart key" which allows you to summon your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.

Most key fobs today include security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a unique unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy the replacement keyfob at an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car.

This includes the labor cost to program the keyfob as well as any replacement parts.

This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming tool can either be an inexpensive handheld device or a high-end one that can do various things beyond just key programming (like reading and cloning Eeprom files within the ECU).
