20 Myths About Automotive Locksmith Key Programming: Busted
Automotive Locksmith Key Programming

Most modern-day cars require some type of key programming. Depending on the model and manufacturer the procedure could be as simple as using an extra key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.

Most US and Asian automobile manufacturers use the same programming protocols as auto tool makers in order to create hardware and software for automotive locksmiths to use.

Transponder Chips

Most newer cars use transponder chips to stop car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing car theft. This technology has also saved car owners a great deal of money since they don't have to replace their vehicles.

This antenna is programmed with the frequency of the chip within the key. The onboard computer in the car will then recognize the key as valid and will allow fuel flow and power the starter to start the engine.

Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.
