Automotive Locksmith Key Programming

Modern cars need some type of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming with a spare key that works or as complex as EEPROM or OBD2 programming.

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