Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the model and make the procedure could be as simple as using an additional key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a huge amount of money as they do not have to buy new vehicles.

Transponder chips have dramatically decreased the likelihood of theft.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will detect that the key is legitimate and allow the fuel to flow, then power up the starter, or even start it.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it is essential to ensure that your locksmith for automotive is equipped to program your car's keys and fobs properly.

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of electronic systems. This is why it should be left to a professional that has extensive experience working with these kinds of systems.
Locksmiths can program keys quickly with onboard programming. It can take less than a minute when everything is executed correctly. If the key isn't in the proper situation or the procedure isn't adhered to, it could take up to a half hour.
