Automotive Locksmith Key Programming: The Good The Bad And The Ugly
Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and make the process could be as simple as using an additional key fob programmers near me to program the onboard computer or as complex as EEPROM or OBD2 programming car key.
The majority of US and Asian car makers use the same programming protocols as auto tool makers to allow them to develop hardware and software for automotive locksmiths to use.

This antenna is programmed to detect the specific frequency of the chip inside the key.
