Automotive Locksmith Key Programming

Modern cars require some type of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using an extra working key or as complicated as OBD2 or EEPROM programming.

Most US and Asian car makers use the same programming protocols as auto tool manufacturers to allow them to develop hardware and software for automotive locksmiths to use.

Transponder Chips

Transponder chips are found in a lot of modern cars to stop theft of cars. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel.

Transponder chips have drastically reduced the number of thefts.

When you insert the transponder keys in the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The car's onboard computer will then detect that the key is valid and allow fuel to flow, turn up the starter, or even start it.
