Automotive Locksmith Key Programming Modern cars require some type of key programming Depending on your vehicles model and manufacturer the process may be as simple as using an additional key to program the onboard computer or as complex as EEPROM or OBD2 programming Most US and Asian automakers share their programming protocol with auto tool manufacturers so they can create hardware or software for automotive locksmiths Transponder Chips Most modern cars are equipped with what are called transponder chips in order to prevent theft These are small computer microchips that emit lowlevel radio signals They have an unique serial number that authenticates your key whenever you plug it into the ignition barrel If your vehicle doesnt recognize the signal it will shut down This technology has been an immense success in stopping auto theft This technology has also saved car owners a great amount of money by not having to purchase new cars The principle behind the transponder system is to make it difficult for thieves to get into your car without the proper key In the past car thieves would simply force your ignition switch to the on position with an ordinary screwdriver or use hot wires to disable the system altogether These types of thefts have been drastically reduced with the introduction of the transponder chip When you insert a transponder keys into the ignition it will transmit the signal which is detected by a hidden antenna that is positioned around the barrel of the ignition This antenna is programmed to detect the specific frequency of the chip inside the key The onboard computer of the car will then recognize the key as being valid and allow fuel flow and power the starter to start the engine Based on the manufacturer some vehicles will only recognise the specific type of transponder chip It is therefore important that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle A reputable locksmith for cars should have a multivehicle key programming tool that is compatible with different car manufacturers and models This is a far cheaper alternative than buying specific tools for each model of vehicle There are also speciallydesigned automotive key programmer devices that can only be used on specific brands of vehicles however they are less frequently used The best automotive locksmiths will have the right tools to deal with any kind of vehicle so ensure you choose a reputable business that has these types of tools Key FOBs Key FOBs are programmeable transponder chip devices that permit your vehicle to unlock doors and start the engine using the push of a button ignition You can also use the buttons to activate features like trunk locks door locks or control of the fuel flap Some fobs can be controlled by pressing buttons For example the smart key that allows you summon your car to tight parking spaces such as the Genesis GV60 or a Tesla or Genesis GV60 While some replacement keys can be programmed by you using the aid of a users guide youll often require an auto locksmith to get a new one programmed if yours stops working This is because a professional locksmith has the right equipment and access to the programming tools required to connect your cars computer via the OBD OBD port located beneath the steering wheel Today most key fobs include security features that make it difficult for hackers to clone or replicate the signals they transmit Certain key fobs come with pseudorandom code generators that generate a unique unlock code each time you press the button This is to prevent attackers from capturing and replaying the unlock signal to gain access to your car In most cases you can purchase an additional key fob at the dealer or other retailer and then have it programmed by your locksmith in your car to be compatible with your specific vehicle This is because most of the major US and Asian automobile manufacturers have key fob programming protocols with thirdparty companies who create the tools auto locksmiths employ to programme keys for their customers While some of the aftermarket key fobs are marketed as being compatible with any vehicle However the majority of locksmiths in the automotive industry dont recommend using them as they are likely to function poorly or not at all Instead they recommend purchasing fobs designed specifically for your specific vehicle so that you can be sure theyll work properly and are less prone to issues like interfering or incompatibility This will save you money over time by avoiding costly repairs or replacements for your fobs Vehicle Manufacturers Programming Tools The automotive industry has made great advances in the last couple of decades Todays cars are

hands of experienced professional auto locksmiths The cost of the car key fob can vary depending on the model and type of key but is usually between 85 to 400 This includes the cost of labor to program the keyfob and any replacement parts To make the process more complicated these car key fobs use a special software system to work with the cars onboard computer The software prevents unauthorised access by only permitting keys that have been programmed specifically for a particular car to work This means that if you need your keys replaced youll have to have the new key fob programed to the car for it to function The most common way to do this is by using an auto key programming tool that is compatible with the model of the vehicle This tool permits a locksmith to connect to the OBD port in the vehicle and then enter the programming mode The key programming device can be a handheld device that is cheap or sophisticated and capable of doing more than just programming keys like reading the eeprom files in the ECU reprogram car key try to program their keys by themselves using these tools However this should be left to an expert auto locksmith Unless

knowledgeable professional can help you avoid these issues OnBoard programming If your car is older than it could still be equipped with a key made of steel that you can use to unlock doors and turn off the ignition However modern cars are equipped with a transponder chip that must be recognized by the computer system to begin This adds another layer of security to keep thieves from starting and driving away with a stolen car A licensed locksmith will have the necessary tools and software to program a new key that is compatible with the security system in your car First your locksmith will

transmit an electronic code The computer will recognize the code and add it to the list of approved keys In some cases scanners can erase keys that were stolen or lost You can also program new keys by using EEPROM It is more complicated and requires a thorough understanding of how electronic systems operate This is why its best left to a professional that has a lot of expertise working on these types 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 completed correctly However if the key isnt placed in the proper situation or the procedure is not followed exactly it can take as long as a half hour There are a variety of key programmer scanners that support different makes and models of vehicles Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of models for vehicles No system can program every vehicle Furthermore these systems are expensive Its best to purchase an instrument that receives regular updates from the manufacturer when new technologies are released Otherwise your programming machine will be obsolete in a short time
