Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the car'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 automakers share their programming protocol with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of 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 vehicle does not recognize the signal it will shut down. This technology has been an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money by not having to purchase new cars.
The transponder system's basic idea is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, thieves would force your ignition switch to the "on" position with the flat screwdriver, or use hot wires to disable the system entirely. These types of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will send an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip within the key. The car's computer onboard will recognise that the key is legitimate and allow fuel to flow, power up the starter, or even start it.
Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it is essential to ensure that your automotive locksmith has the right equipment to program your car's key and fobs correctly.

The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reputable firm that has this kind of equipment.
Key FOBs

This is accomplished by using a programming tool for car keys that is compatible with the vehicle's brand. This tool allows locksmiths to connect to the OBD port in the vehicle and then enter programming mode. The key programming tool could either be an inexpensive handheld device or a more expensive one that can perform various things that go beyond key programming (like reading and cloning eeprom files in the ECU).

The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires an in-depth understanding of how electronic systems function. It is best to delegate it to a professional with expertise with these systems.
Onboard programming is the fastest method for locksmiths to program an entirely new key. If everything is done properly, it can take just one minute. If the key isn't in proper state or the procedure is not strictly followed, it could take up to a half hour.
