The Basics of Key Programming Key programming isn't as easy as it might seem. The majority of people go to a locksmith or dealer to do this. With the right equipment, brick and mortar parts departments can handle the key programming. This article will cover some of the basics of key coding to help get your shop going. Modern vehicles Modern cars utilize a variety of electronic devices to connect with the car's internal systems. These systems include key fobs and remote start systems. Key programming for vehicles has become an an essential part of the automotive industry because it ensures that these devices are working correctly. In the past, cars depended on simple keys made of metal to unlock doors and start engines. Keys like these were easy to copy of and could be stolen or lost. Most vehicles now include key fobs with transponders inside. These chips connect the key to the car system, ensuring only the right person is able to open and start the car. This is important as it makes it harder for thieves to steal cars and allows owners to easily replace a damaged or lost key. A lot of modern cars also come with security features which prevent them from starting unless the correct key is in place. These systems are great to keep your vehicle safe from theft. However they require you to learn how to program your keys correctly. If you're a locksmith or auto technician, having key programming capabilities is essential. You may need to perform this service in three distinct scenarios: In the beginning, you may be able to assist a customer who is having difficulty getting their car to start. This issue usually occurs when the remote control isn't properly programmed. This problem can be resolved by using a key programming tool that is compatible with the model of your vehicle. This service could be required if you are adding an additional key to your vehicle. Key programming is onboard in the majority of modern vehicles. This procedure uses a specific scan tool to read the unique ID in the new remote or key and then send that information to the vehicle's system. Some key programming tools can even operate bidirectionally, allowing them to transfer data between two different vehicles. This is especially useful when an element needs to be replaced or flashed. This is important as it can save time and money by reducing the amount of time you wait for the correct part to arrive from overseas. Transponder Chips Many modern vehicles have transponder chips that communicate with the computer system of the car. When a key is put into the ignition barrel, the chip sends a signal that contains a digital code that uniquely can identify it as a genuine car key. This technology adds a security layer to modern cars and lowers the risk of theft. However, to benefit from this added security feature the key needs to be properly cut and programmed. This service can be offered by a qualified auto locksmith or dealer. The first step to reprogramming a transponder is ensure that the key is equipped with an electronic circuit board or transponder of the right type. The key must also be compatible with the vehicle's onboard computer and have an appropriate key ring positioned correctly around the ignition barrel. This kind of reprogramming is usually done with the transponder cloning machine that can copy a particular circuit board or transponder. Some key blank manufacturers as well as some reprogramming experts offer this equipment. The device that is cloned must be capable of reading the information that is transmitted on each transponder that are being cloned. Some cloning machines are upgradeable, and can be used to copy the most recent transponders. A locksmith who offers transponder key reprogramming will also have the necessary tools to ensure that the new key is properly cut. They can also provide an alternative key that has an authentic transponder or generic key that works on the vehicle. They can also assist the customer in obtaining the correct blank key. Transponder keys are an vital element of the security and safety features of modern vehicles. They are designed to avoid hot-wiring of a vehicle, which is among the most common ways that thieves steal cars. The transponder chip makes it almost impossible to start a vehicle without a key. A professional automotive locksmith can install a transponder chip and program it into the vehicle so that it can be started. PIN codes PIN codes can be used in a variety of ways to safeguard private information from cyber and physical attacks. A PIN code is generally a six-digit or four-digit sequence of numbers that is used to verify transactions between banks and other devices for credit card as well as between citizens and governments employees, businesses and government officials and computers as well as users and employees. A lot of automakers now require keys to transmit the unique VIN number of the vehicle along with the transponder code. These additional security measures usually require specific key programming procedures which are not available to independent mechanics unless the have access to a dealer-only tool, such as Autel's Immobilizer scan tool IM608 or Launch Tech’s XProg3 scanner. It's important that you choose a PIN which is easy to remember, but difficult to be recognized by other people. The majority of experts suggest a combination of numbers and letters. Avoid using personal information, such as birthdates, phone numbers or social security numbers. They can be easily identified. To ensure your security ensure that your PIN is at least six digits in length. This makes it more difficult for hackers to guess your PIN, although 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 does not require an extant copy of the data, this may not be an issue – however, it could be a problem when the data is changing or requires updating continuously. Idealy, one copy of the data should be discarded when it's no longer needed. In some cases the transfer of data may involve a third party such as an IT department or cloud service provider. In programming car key to understand who is responsible for managing the process of transfer and the data involved. This can help to prevent any issues that might arise from unauthorized data access or corruption. Key programming is an excellent tool for auto repair shops to utilize however, there are certain limitations that technicians need to keep in mind. First, Putrino said that a shop must obtain an ID for locksmiths (LSID). This credential provides technicians with 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. These scan tools will require to retrieve the PIN code from the modules, and allow technicians to program new keys. Many OEMs also require that the key transmits more than the ID code. VW, Chrysler, and other manufacturers require that the key transmits the unique VIN number of the vehicle. These additional transmissions can be programmed by using an instrument for programming keys. A lot of technicians don't offer key programming, but those who do can make a lot of money. For shops wanting to get started, Putrino recommended considering a professional key programming tool, such as the XTool USA AutoPro Pad. This tool is capable of various functions that include EEPROM read and write, BMW CAS3/2 key learning remote learning for Mercedes Benz FEM, and more.
