Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and manufacturer, the process may be as simple as using an extra key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian car makers have programming protocols that they share with auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are small computer microchips 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 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 saved car owners a great amount of money by not having to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to start your car without a key.

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 the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will then recognise that the key is legitimate and allow fuel to flow, turn up the starter, or even begin it.
Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip. It is therefore important that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.

In many instances you can purchase an alternative key fob from the dealer or from another retailer and then have it programmed by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that create the tools used by auto locksmiths to program their customers' keys.
