Automotive Locksmith Key Programming The majority of modern cars require some form of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming 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 automotive locksmiths to use. Transponder Chips Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio waves. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been an enormous success in preventing theft of cars. It also saves many car owners a significant amount of money since they don't have to buy new their vehicles. The basic concept behind the transponder system is to make it hard for thieves to get into your vehicle without a valid key. In the past, thieves would simply force your car's ignition switch into the “on” position with a flat screwdriver or even hot-wire the car to bypass the system entirely. These kinds of thefts have been dramatically reduced with the introduction of the transponder chip. When you insert the transponder key into the ignition, the signal is received by an antenna that is hidden within the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The onboard computer of the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine. Based on the manufacturer, certain vehicles can only recognize certain types of transponder chip. This is why it is important to ensure that your automotive locksmith is equipped to program your vehicle's keys and fobs correctly. A reputable locksmith for automotive needs to have a multi-vehicle key programming device that is compatible with different models and manufacturers of cars.

While some replacement keys can be programmed by you with the assistance of a user's manual, you'll often require an automotive locksmith to get a brand new one programmed if the one you have isn't working.

The majority of key fobs today include security features that make it difficult for attackers to duplicate or copy the signals they transmit. They include pseudo-random generators that generate a new unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle. In most cases you can purchase an additional key fob at the dealership or another retailer and have it programmed by your locksmith in your car to work with your specific vehicle. This is because the majority of the major US and Asian car manufacturers share their key fob programming protocols with third-party firms that make the tools that locksmiths use to program keys for their customers.
