Automotive Locksmith Key Programming

Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming using a spare working reprogram key fob or as complicated as OBD2 or EEPROM programming.

The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can design tools or hardware for automotive locksmiths.

Transponder Chips

Transponder chips are found in many newer cars to prevent reprogram car key theft. These are tiny computer microchips which emit radio signals of low-level. The microchips have a unique serial number which authenticates your key whenever you insert it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been an immense success in stopping auto theft. It also saves many car owners a lot of money since they don't have to buy new their cars.

These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.

When you place the transponder key in the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to detect the specific frequency of the chip within the key.

The majority of key fobs today include security features that make it difficult for attackers to clone or replicate the signals they transmit. Certain key fobs come with pseudo-random code generators which generate a new unlock code each time you press the button.
