4 Dirty Little Details About The Automotive Locksmith Key Programming Industry Automotive Locksmith Key Programming

Modern automobiles require some kind of key programming. Based on the car's make and model, the procedure can be as simple as programming onboard using a spare working key or as complicated as EEPROM or OBD2 programming.

This antenna is programmed with the frequency of the chip within the key.
