Automotive Locksmith Key Programming Modern cars need some type of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming. Most US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can design software or hardware for locksmiths in the automotive industry. Transponder Chips Most modern cars are equipped with transponder chips to stop car theft. These are small computer microchips that emit low-level radio signals. The microchips are equipped with a unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be a huge success in preventing car theft. It also saves many car owners a significant amount of money as they don't need to replace their vehicles. The basic concept behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without the correct key. In the past car thieves used a flat screwdriver to force the ignition switch of your vehicle into “on” mode or even hot-wire it to get around the system. These kinds of thefts have been drastically reduced thanks to the introduction of the transponder chip. When you insert a transponder keys into the ignition, it will send a signal that is received 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 onboard computer of the car will then recognize the key as being valid and will allow fuel flow and power the starter to start the engine. Depending on the manufacturer, certain vehicles can only accept the specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the right equipment to program your car's keys and remotes.

It is also possible to press buttons to activate features like door locks, trunk releases or fuel flap controls. Some fobs have additional functions that can be controlled by the push of a button for example, a “smart” key fob that lets you get your car into tight parking spots as you would with the Genesis GV60 or Tesla. Tesla or Genesis GV60.
