Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process can be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian automobile manufacturers share their programming protocols with auto tool makers to allow them to develop software and hardware for locksmiths working in automotive vehicles.

This antenna is programmed with the frequency of the chip in the key. The car's onboard computer will recognize that the key is valid and allow fuel to flow, turn the starter or begin it.

Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their broad range of vehicle models. No system can program every vehicle.
