Automotive Locksmith Key Programming Modern vehicles require some form of key programming. Based on the car's make and model, the procedure can be as easy as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming. Most US and Asian car makers have programming protocols that they share with auto tool makers to allow them to develop hardware and software for locksmiths in the automotive industry to use. Transponder Chips Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number which authenticates your key whenever you connect it to the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be an enormous success in preventing car theft. This technology has also helped car owners save a good amount of money since they don't have to purchase new cars. The principle of the transponder system is to make it hard for thieves to open the doors of your car without the right key. In the past car thieves used an ordinary screwdriver to force the ignition switch of your car to go into “on” mode or even wire it hot to get around the system. Transponder chips have dramatically reduced these types of thefts. When you insert a transponder keys into the ignition, it will send the signal which is received by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The computer onboard of the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine. Based on the manufacturer, certain vehicles can only recognize certain types of transponder chip. This is why it's crucial to make sure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs properly.

The majority of key fobs are equipped with security features that make it harder for attackers replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators which generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle. In many instances, you can purchase an alternative key fob from the dealer or from another retailer and then have it programmed by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that make the tools used by locksmiths who program their customers' keys. Some aftermarket key fobs may be advertised as being compatible with vehicles of all kinds. However, professional locksmiths strongly discourage using them as they're more likely to perform poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they work correctly and are less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing your fobs.
