Automotive Locksmith Key Programming Modern automobiles require some kind of key programming. Based on the model and manufacturer the procedure could be as simple as using a spare key to program the onboard computer or as complex as EEPROM or OBD2 programming. Most US and Asian automakers have a programming protocol that they share with auto tool makers, so they can design software or hardware for locksmiths in the automotive industry. Transponder Chips Transponder chips are in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit radio signals at a low level. The microchips have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has proved to be an enormous success in preventing auto theft. This technology has also helped car owners save a good amount of money as they do not have to replace their vehicles. The basic idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car into the “on” mode, or wire it hot to evade the system. Transponder chips have dramatically reduced the number of thefts. When you insert a transponder key into the ignition, it will send the signal which is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The car's computer onboard will detect that the key is genuine and allow the fuel to flow, then power up the starter or begin it. Certain vehicles only recognize a specific type of transponder chip, depending on the manufacturer. Therefore, it is essential that your locksmith for cars is equipped with the appropriate equipment to program your keys and remotes for your vehicle. A reliable locksmith for cars will have a multi-vehicle programming device which can be used on a variety of different automobile models and manufacturers.

These are less common, but there are specialised automotive key programmers that can only be used on a specific type of vehicle. The best automotive locksmiths will have the right tools to work on any type of vehicle, so make sure you choose a reputable firm that offers these types of tools. Key FOBs As the name suggests, key FOBs contain programmable transponder chips that enable your vehicle to recognize and open the doors, or start the engine using push-button ignition. They also have buttons that you can push to activate features such as door locks, trunk release or fuel flap control. Some fobs can be controlled using buttons. For example the “smart key” which allows you to summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60. You can program spare key fobs by yourself with the assistance of an instruction manual, however you'll need to call an automotive locksmith in the event that yours has stopped functioning. A professional is better equipped to connect your computer to the vehicle to the OBD port on the steering wheel. Today, most key fobs include security features that make it difficult for hackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code every time you press the button on your key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle. In some cases, you can buy the replacement keyfob at an authorized dealer or another retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who make the tools used by locksmiths for programming their customer's keys. Although some key fobs from the aftermarket are advertised as compatible with any vehicle however, the majority of locksmiths for automotive don't recommend using them because they're likely to work poorly or not at all.
