Automotive Locksmith Key Programming Most modern-day cars require some type of key programming. Based on the model and make, the process may be as simple as using a spare key to programme the computer onboard, or as complex as OBD2 programming or EEPROM. The majority of US and Asian car makers use the same programming protocols as auto tool manufacturers to allow them to develop tools and hardware for locksmiths working in automotive vehicles. Transponder Chips Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio waves. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing theft of cars. It has also saved many car owners a lot of money as they don't have to buy new their cars. The fundamental idea behind the transponder system is to make it impossible for thieves to get into your car without a key. In the past, car thieves would simply force your ignition switch to the “on” position using an ordinary screwdriver or make use of hot-wires to bypass the system completely. These types of thefts have drastically reduced with the introduction of the transponder chip. When you insert a transponder key into the ignition, it will send an electrical 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 car's computer onboard will recognise that the key is genuine and allow the fuel to flow, then power the starter or begin it. Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it is essential to ensure that your locksmith in the automotive industry has the appropriate equipment to program your car's keys and fobs correctly.

Some fobs also have additional functions that can be controlled with the press of a button for example, a “smart” key fob that allows you to get your car to parking spots that are tight similar to a Tesla or Genesis GV60. You can program spare key fobs by yourself with the assistance of an instruction manual, however you will need to call an automotive locksmith in the event that yours has stopped functioning.

The majority of key fobs are equipped with security features that make it more difficult for criminals to duplicate and copy the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a different unlock code every time you press the button.

Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that make the tools used by auto locksmiths to program their customers' keys.
