Automotive Locksmith Key Programming

The majority of modern cars require some form of key programming. Depending on the model and manufacturer the process could be as simple as using an extra key to program the onboard computer or as complicated as OBD2 programming or EEPROM.

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

Transponder Chips

Most modern cars are equipped with transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been a huge success in preventing car theft.

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

When you insert the transponder keys in the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to read the specific frequency of the chip inside the key. The computer onboard of the car will then recognize the key as valid and will allow fuel flow and start the starter. start the engine.
