Automotive Locksmith Key Programming

Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.

The majority of US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can design tools or hardware for locksmiths in the automotive industry.

Transponder Chips

These kinds of thefts have drastically reduced with the introduction of the transponder chip.

When you place the transponder key into the ignition the signal is picked up by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip within the key.
