Automotive Locksmith Key Programming: The Good, The Bad, And The Ugly

Automotive Locksmith Key Programming

Most modern-day cars require some kind of key programming. Based on the car's make and model, the process can be as easy as programming onboard using a spare key that works or as complex as EEPROM or OBD2 programming.

Transponder Chips

Transponder chips are used in a variety of newer vehicles to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have 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 theft of cars.

These kinds of thefts have been dramatically decreased with the introduction of the transponder chip.

When you place the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will then recognize the key as valid and allow fuel flow, power the starter or start the engine.

Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the correct equipment to program your car's keys and remotes.
