Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using an extra working key or as complex as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips to stop car theft. These are tiny computer microchips which emit radio waves of low-level. The microchips have an unique serial number that authenticates your key when you plug it into 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 good amount of money by not having to purchase new cars.
The basic concept behind the transponder system is to make it hard for thieves to start your vehicle without a valid key. In the past, thieves would simply push your ignition switch to the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system entirely. These kinds of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys in the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will detect that the key is genuine and allow the fuel to flow, then power up the starter, or even begin it.
Depending on the manufacturer certain vehicles can only accept the specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the correct equipment to program your car's keys and remotes.
