Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the procedure can be as simple as onboard programming using an extra working key or as complex as EEPROM or OBD2 programming.
Most US and Asian car makers use the same programming protocols as auto tool manufacturers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. The microchips are equipped with a unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has been a huge success in preventing theft of cars. This technology has also saved car owners a great deal of money by not having to replace their vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to open the doors of your car without the right key. In the past, thieves would use the flat screwdriver to push the ignition switch of your car into "on" mode, or hot-wire it in order to evade the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits a signal that is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will detect that the key is genuine and allow the fuel to flow, then power the starter or begin it.
Some vehicles only recognize certain type of transponder chips, depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.

You can also 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 by the button presses, such as the "smart" key fob that lets you bring your car to parking spots that are tight, like you would with the Genesis GV60 or Tesla.

Most key fobs today come with security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code each time you press the button. This is to prevent attackers from capturing and replaying the unlock signal to gain access to your car.
In many instances you can buy an additional key fob at the dealer or from another retailer and have it programmable by your locksmith in your car to fit your specific vehicle. This is due to the fact that most of the major US and Asian car manufacturers use key fob programming protocols with third-party firms that make the tools that locksmiths employ to program keys for their customers.
While some of the aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths do not recommend using them because they are likely to function poorly or not at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less prone to issues like interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing your fobs.
