Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the car's make and model, the process could be as simple as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car makers share their programming protocols with auto tool makers so that they can develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been a huge success in preventing car theft. It also saves many car owners a significant amount of money because they don't have to replace their vehicles.

In the past, car thieves would simply push your ignition switch to the "on" position using the flat screwdriver, or use hot wires to disable the system entirely. These types of thefts have drastically reduced with the introduction of the transponder chip.
When you place the transponder key into the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The car's onboard computer will detect that the key is valid and allow fuel to flow, power up the starter, or even begin it.
Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it's important to ensure that your locksmith for automotive is equipped to program your vehicle's keys and fobs correctly.
