Automotive Locksmith Key Programming Modern vehicles require some form of key programming Depending on the model and make the procedure could be as simple as using a spare key to program the onboard computer or as complex as EEPROM or OBD2 programming The majority of US and Asian car makers share their programming protocols with auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles Transponder Chips Transponder chips are found in a variety of newer vehicles to stop theft of cars These are tiny computer microchips that emit radio signals at a low level The microchips are equipped with a unique serial number which authenticates your key whenever you insert it into the ignition barrel If your vehicle doesnt recognize the signal it will shut down the engine This technology has been an incredible success in preventing auto theft It also saves many car owners a lot of money as they dont have to replace 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 used an ordinary screwdriver to force the ignition switch in your car to go into on mode or hotwire it in order to evade the system Transponder chips have dramatically reduced these types of thefts When you insert a transponder keys into the ignition it will send an electrical signal that is received by a hidden antenna around the barrel of the ignition This antenna is programmed with the frequency of the chip inside the key The cars onboard computer will then recognise that the key is genuine and allow the fuel to flow then power up the starter or begin it Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip Therefore it is essential that your automotive locksmith is equipped with the right equipment to program your cars keys and remotes A good automotive locksmith should have a multivehicle key programming device that is compatible with different models and manufacturers of cars This is a less expensive solution than buying separate tools for each brand of vehicle These are less common but there are specialised automotive key programming tools that can only work on a particular model of vehicle The best automotive locksmiths will have the proper tools to deal with any kind of vehicle so be sure you choose a reputable business that has these types of tools Key FOBs The key FOBs are programmable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button You can also press buttons to activate features like door locks trunk releases or control of the fuel flap Certain fobs can be controlled using buttons For example the smart key that lets you call your car into tight parking spaces like the Genesis GV60 Tesla or Genesis GV60 While some replacement keys can be programmed with the help of a user manual but youll usually require an automotive locksmith to have a new one programmed if the one you have isnt functioning A professional is better equipped to connect your computer to the vehicle to the OBD port on the steering wheel The majority of key fobs are equipped with security features that make it more difficult for criminals to duplicate and copy the signals that they transmit Certain key fobs feature pseudorandom code generators which generate a unique unlock code every time you press the button This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle In most instances you can purchase an alternative key fob from the dealer or other retailer and then have it programmed by your locksmith in your car to fit your specific vehicle This is because the majority of major US and Asian auto manufacturers use the same keyfob programming protocol with the thirdparty firms who make the tools used by auto locksmiths to program their customers keys While some aftermarket key fobs are marketed as being compatible with all vehicles However the majority of locksmiths in the automotive industry dont recommend using them because they will likely only work poorly or not at all They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less prone to issues such as interference or incompatibility This will save you money over time as you avoid costly repairs or replacements for your fobs Vehicle Manufacturers Programming Tools The automotive industry has come a long way and modern vehicles require computer technology to function One key element of this technology is a transponder chipset that requires to be programmed to the vehicle by a locksmith or dealermechanic in order to work Key fobs come with builtin security features that prevent hotwiring like in a film and the car wont start if it doesnt have the correct key Key fobs can be slightly more complicated than a standard mechanical key This is why theyre usually handled by experienced professional auto locksmiths The cost of a car key fob varies depending on the type and model of key but it is typically between 85 to 400 This includes the labor cost to program the keyfob as well as any replacement parts To complicate the process these car key fobs use a special software system to communicate with the cars onboard computer The software blocks unauthorized access by permitting the key to function only if its been programmed to that specific car If you decide to replace your keys you will have to program the new key fob in the car for it to work The most common way to accomplish this is using a car key programming tool that is compatible with the model of the vehicle This tool allows a locksmith to connect to the OBD port on the vehicle and then enter programming mode Key programming tools can be a simple handheld device or a fancy one that is capable of performing a wide range of things beyond key programming like reading and cloning the EEEPROM files in the ECU While some people may attempt to program their own keys using these tools this is an activity best left to a professional auto locksmith If youre not familiar with the ins and outs of the various software systems its very easy to accidentally alter settings that could potentially damage the vehicle The most important thing to remember is that an experienced professional can help you avoid these problems OnBoard programming If your car is older than it may still come with a key made of steel that you can use to unlock doors and turn on the ignition Modern cars have a transponder that must be recognized and accepted by the computer system to start This is an extra layer of protection that can stop car thieves from stealing a car and driving away with it A locksmith certified will have the tools and software needed to program a key that can work in your cars system The locksmith will need to get a blank key that is compatible with the model and make of your vehicle Once your locksmith has the key hell connect the programming scanner to the diagnostic port of your vehicle This will put the car into a special programing mode which allows the locksmiths to add the key to the system The key scanner that is programmed communicates with the computer in the vehicle to send a code The computer will recognize the code and add it to the list of keys approved by In some cases the scanner will be able to delete keys that have been stolen or lost from the system You can also program new keys with EEPROM It is more complex and requires an indepth understanding of how electronic systems work This is why its best left to a professional that has a lot of experience working with these kinds of systems Onboard programming is the most efficient way for a locksmith to program an entirely new key It takes as little as one minute if everything is done correctly If the key isnt in good working order or the procedure isnt being followed exactly the process could take as long as a half hour There are many key programmer scanners available that work with various vehicle models and brands The Smart Pro and the Autel IM608 Pro are both extremely wellliked by locksmiths due to the fact that they can be used with a variety of vehicles No system can program every vehicle Additionally these devices are expensive It is best to buy one that will receive regular updates from the manufacturer when new technologies are developed Otherwise your programming machine will become obsolete quickly
