Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers use the same programming protocols as auto tool makers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are microchips in the form of computers 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 proven to be an enormous success in preventing car theft. It has also saved many car owners a significant amount of money because they don't have to buy new their cars.
The principle of the transponder system is to make it impossible for thieves to get into your vehicle without the correct key. In the past, car thieves would force the ignition switch of your car into the "on" position with the flat screwdriver, or use hot wires to disable the system completely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert the transponder keys into the ignition the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognise the key as valid and will allow fuel flow and power the starter to begin the engine.
Depending on the manufacturer, certain vehicles can only recognize the 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 vehicle's keys and fobs properly.

Key FOBs

For instance, a "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself using the help of a user guide, but you'll need to contact an automotive locksmith if yours has stopped functioning.

The majority of key fobs today have security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code each time you press the key fob's button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
