Automotive Locksmith Key Programming: 10 Things I'd Love To Have Known In The Past

Automotive Locksmith Key Programming

Modern vehicles require some form of key programming. Based on the model and make the procedure could be as simple as using an extra key to program the onboard computer, or as complex as OBD2 programming or EEPROM.

The majority of US and Asian car manufacturers share their programming protocols with auto tool manufacturers to allow them to develop hardware and software for locksmiths working in automotive vehicles.

Transponder Chips

The majority of newer cars have transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has proven to be an enormous success in preventing car theft.

Transponder chips have drastically decreased the likelihood of theft.

When you place the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip inside the key.
