Automotive Locksmith Key Programming

Modern cars require some type of key programming. Depending on the car's maker and model, the process could be as simple as onboard programming with an extra working key or as complex as EEPROM or OBD2 programming.

The majority of US and Asian automakers share their programming protocol with auto tool manufacturers, so they can develop software or hardware for automotive locksmiths.

Transponder Chips

Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level.

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

When you insert the transponder key into the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer of the car will then recognize the key as valid and allow fuel flow and power the starter to start the engine.

Based on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.
