Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer, the process may be as simple as using an extra key to program the onboard computer or as complex as EEPROM or OBD2 programming.

The antenna is programmed with the frequency of the chip inside the key.
