Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and make, the process may be as simple as using a spare key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers share their programming protocols with auto tool manufacturers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has been an incredible success in preventing auto theft.

Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder key into the ignition, it will send a signal that is received by a hidden antenna around the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's onboard computer will then detect that the key is valid and allow the fuel to flow, then power up the starter, or even begin it.

Key programming tools can be a simple handheld device or a more expensive one that can do many things that go beyond key programming (like reading and cloning the eeprom files click here in the ECU).

In certain instances, the scanner will also be able to erase keys that have been stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a deep understanding of how electronic systems operate. This is why it's best left to a professional who has years of expertise working on these types of systems.
Locksmiths can program keys quickly using onboard programming. When everything is done correctly it could take as little as one minute. If the key isn't in the proper state or the procedure is not strictly followed, it could take as long as a half hour.
There are numerous key programmer scanners available that work with various car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their broad range of models for vehicles. The system cannot program every vehicle. They are also expensive. It is best to buy a programmer which will receive regular updates from the manufacturer when new technologies are developed.
