Automotive Locksmith Key Programming 10 Things I'd Like To Have Learned Sooner

Automotive Locksmith Key Programming

Modern cars require some type of key programming. Depending on the model and make the process 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 auto manufacturers have a programming protocol that they share with auto tool makers, so they can design hardware or software for automotive locksmiths.

Transponder Chips

Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips that emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car 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 extremely successful in preventing car theft. This technology has also saved car owners a great amount of money since they don't have to purchase new cars.

The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will then recognise that the key is valid and allow fuel to flow, power the starter or begin it.
