Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional 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 makers, which means they can design hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to stop theft of cars. These are microchips in the form of computers that emit radio signals 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 car doesn't recognise the signal it will stop the engine. This technology has been an enormous success in preventing theft of cars. It has also saved many car owners a significant amount of money as they don't have to buy new their cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past, car thieves would simply push your ignition switch to the "on" position with a flat screwdriver or even use hot wires to disable the system entirely. Transponder chips have drastically reduced these types of thefts.
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 recognize that the key is genuine and allow fuel to flow, turn the starter or start it.

If you change your keys, you'll need to program the new key fob into the car to allow it to function.
The most popular method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter an programming mode. The key programming device could be a handheld device that is affordable or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).

Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of how electronic systems function. It is best to delegate it to a professional who has experience with these systems.
Locksmiths can program a key quickly by using onboard programming. If everything is done properly, it can take just one minute. If the key isn't in good working order or the procedure isn't followed exactly, the process could take up to half an hour.
There are a variety of key programmer scanners which can work with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they cover a wide range of vehicles. No system can program every vehicle. Additionally, these devices are expensive.
