Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Based on the model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been a huge success in preventing theft of cars. This technology has also saved car owners a great deal of money as they do not have to buy new vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to start your car without the right key. In the past, car thieves would simply push the ignition switch of your car into the "on" position using an ordinary screwdriver or use hot wires to disable the system altogether. These kinds of thefts have been drastically reduced with the introduction of the transponder chip.
When you place the transponder key into the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed to read the specific frequency of the chip inside the key. The onboard computer of the car will then recognize the key as valid and allow fuel flow and power the starter to begin the engine.
Certain vehicles only recognize a certain type of transponder chip, depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
