20 Myths About Automotive Locksmith Key Programming: Busted
Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the model and make the process could be as simple as using an additional key to program the onboard computer, or as complex as OBD2 programming or EEPROM.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, so they can design hardware or software for automotive locksmiths.

This antenna is programmed so that it can detect the specific frequency of the chip within the key.
