Ten Things You Need To Know About Automotive Locksmith Key Programming

Automotive Locksmith Key Programming

Most modern-day cars require some type of key programming. Based on the model and manufacturer the process could be as simple as using an extra key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.

The majority of US and Asian car makers share their programming protocols with auto tool manufacturers in order to create hardware and software for locksmiths in the automotive industry to use.

Transponder Chips

Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips that emit radio signals at a low level. The microchips are equipped with an unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge deal of money since they don't have to purchase new cars.

The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key.

Transponder chips have dramatically decreased the likelihood of theft.

The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will recognize that the key is legitimate and allow fuel to flow, turn the starter or begin it.

Some fobs have additional functions that can be controlled with the button presses, such as a "smart" key fob that lets you bring your car into parking spaces that are difficult to access, like you would with a Tesla or Genesis GV60.

They include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This prevents attackers capturing and playing back the unlock signal to gain access to your vehicle.

In many cases you can purchase an additional key fob at the dealer or other retailer and have it programmable by a locksmith for your vehicle to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party companies who make the tools used by locksmiths for programming their customer's keys.
