The Basics of Key Programming Key programming isn't as easy as it may appear. In reality, it's a thing that most people will end up visiting the dealer or a locksmith for. With the right equipment, brick and mortar parts departments can handle the key programming. This article will look at the basics of key coding to help get your shop going. Modern vehicles Modern cars make use of a variety electronic devices to communicate with the car's internal systems. These systems include key fobs and remote start systems. Key programming for vehicles has become an important to the automotive industry since it helps ensure that these devices are working correctly. In the past, automobiles relied upon simple metal keys to unlock their doors and start their engines. Keys like these were easy to make copies of and could be stolen or lost. Many vehicles now include key fobs with transponders in them. These chips link the key to the car's system, ensuring only the right person is able to open and start the car. This is crucial as it makes it much more difficult for thieves to steal cars and allows owners to easily replace keys that have been damaged or lost. Many modern vehicles also come with safety features built-in that will not start when they're not accompanied by the correct key. These systems are great to protect your car from theft. However, they require that you learn how to program your keys correctly. You need key programming skills if your a locksmith or auto technician. You could be required to perform this service in three different scenarios: You might be able help a person who is having difficulty getting their car started. This issue usually occurs when the remote control or key isn't programmed correctly. This issue can be resolved with an instrument for programming keys that is compatible with the specific model of the vehicle. This service might also be required if you are adding an additional key to your vehicle. Onboard key programming is available on most modern automobiles. This process uses a scan tool to identify the unique identifier in the new remote or key and transmit this information to the vehicle's system. Some of the most popular programming tools can even work bidirectionally which allows them to transfer data between two vehicles. This is especially useful when a module needs to be replaced or flashed. This is crucial because it can save time and money by cutting down on the time spent waiting for the correct component to arrive from overseas. Transponder Chips Many modern cars have transponder chips that communicate with the car's computer system. When a key is inserted into the ignition barrel, the chip sends out a signal using a digital code that uniquely can identify it as a valid car key. This technology adds an additional layer of security to modern cars, and reduces the risk of theft. However, in order to take advantage of this added security feature the key needs to be cut correctly and programmed. A certified auto locksmith or car dealership can offer this service. The first step to reprogramming a transponder is ensure that the key you are programming has an electronic circuit board or transponder of the right type. The key should be compatible with the on-board computer of the vehicle and have an appropriate keyring placed around the ignition barrel. In most instances, this type of reprogramming will require the use of a special transponder cloning device, which is able to copy a specific transponder or circuit board. Some of the major blank manufacturers as well as experts in reprogramming offer this device. The device that is cloned must be capable of reading the information that is transmitted on each of the transponders which are being copied. Some cloning devices can be upgraded and are able to copy the latest transponders that are being released. A locksmith who offers transponder key reprogramming services will also have the tools to ensure that the new key is properly cut. They can supply a replacement key with authentic transponders or a generic key that works on the vehicle. They can also assist the customer in purchasing the correct blank key. Transponder keys are a very crucial element of the security and safety features in modern vehicles. They are designed to avoid hot-wiring of a vehicle, which is among the most frequent methods used by thieves steal cars. This is because the transponder chip makes it nearly impossible to start a car without a valid key. A professional automotive locksmith can install a transponder chip and program it to the vehicle so that it can be started. PIN Codes PIN codes are used in many different applications to ensure that personal information stays protected from physical and virtual attacks. A PIN code is a sequence of numbers, typically with four or six digits that is required to authenticate transactions with banking systems as well as other devices that use cards, government agencies with citizens, businesses with employees, and computers that have users, among others. Many automakers now require keys to transmit the VIN number of the vehicle, and also the transponder code. These additional security measures need special key programming procedures, which are typically not available to independent mechanics unless they have access to a dealer-only tool such as Autel's Immobilizer Scan Tool (IM608) or Launch Tech's immobilizer scanner. It is essential to select an account number that is easy to remember, but difficult to guess by other people. The majority of experts recommend a combination of letters and numbers. Avoid using personal information such as birthdates, phone numbers or social security numbers. These can be easily identified. Make sure your PIN has at least six digits to ensure the most secure protection. This makes it more difficult for a hacker to brute force to guess your PIN, however there are methods to overcome this. Data Transfer Data transfer results in two copies of the data — one at the source, and one at the destination. If the destination doesn't need an extant copy of the data, this may not be an issue – however, it could be a problem if the data is changing or needs to be updated continuously. Ideally, one copy of the data should be deleted when it's no longer required. In some cases a data transfer can involve a third-party, such as an IT department or cloud service provider. In this case it's crucial to understand who is responsible for managing the transfer process as well as the data being transferred. This will help avoid any issues that might result from unauthorised access to data or corruption. Key programming is a useful tool for auto repair shops to use, but there are certain limitations that technicians must be aware of. First, Putrino said that a shop will need to procure an ID for locksmiths (LSID). This credential gives technicians secure access to the vehicle's immobilizer as well as PIN codes by using the National Automotive Service Task Force's Secure Data Release Model. Also, make sure the shop has scanners that are able to handle the process. reprogram car key must be capable of extracting the PIN code directly from the modules, as well as allowing technicians to program new key. Many OEMs also require that the key transmit more than the ID code. VW, Chrysler, and other manufacturers require that keys transmit the unique VIN number of the vehicle. These additional transmissions can be programmed using an instrument for key programming. A lot of technicians don't offer key programming, but those who do could earn an impressive amount of money. Putrino recommends that businesses who are planning to start an enterprise, consider hiring an expert key programmer such as the XTool USA AutoPro pad. This tool can perform a range of functions including EEPROM read/write, BMW CAS3/2 Key learning, remote learning for Mercedes Benz, and more.
