The Basics of Key Programming Key programming isn't as simple as it appears. Most people will visit an auto dealer or locksmith for this. Brick and mortar parts departments are able to program keys using the appropriate equipment. This article will go over some of the fundamentals of key programming to get your shop started. Modern Vehicles Modern vehicles use a variety of electronic devices to communicate with the car's internal systems. These systems include things like key fobs remote start systems and many more. Key programming for vehicles has become an important to 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. These keys were easy to duplicate of and could be stolen or lost. Many vehicles now have key fobs with transponders in them. These chips connect the key to the car's 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 also allows owners to easily replace keys that are damaged or lost. Many modern cars also have safety features built into them that stop them from starting unless they are accompanied by the proper key. These systems are excellent to keep your vehicle safe from theft. However they require that you know how to program your keys correctly. If you're a locksmith or auto technician, having key programming capabilities is essential. You could be required to provide this service in three different circumstances: You may be able to assist a person who is having difficulty starting their car. This issue usually occurs when the remote control isn't properly programmed. This issue can be solved by using a key programming tool that is compatible with the model of your vehicle. This service may be required if you are adding an additional key to your vehicle. The majority of modern vehicles allow you to add a key through onboard key programming. This process utilizes a scan tool to detect the unique identification in the new remote or key and transmit this information to the vehicle's system. Some key programming tools can even function bidirectionally and transfer data between two vehicles. This is particularly useful in situations where an element needs to be replaced or flashed. This is important as it can save time and money by cutting down on the time you wait for the correct part to arrive from overseas. Transponder Chips A lot of modern cars are equipped with transponder chips that communicate with the car's computer system. When programming car key is inserted into the barrel of ignition, the chip sends out a signal that contains a digital code that uniquely recognizes it as a valid car key. This technology provides an extra layer of security for modern vehicles and helps reduce the possibility of theft. However, to benefit from this additional security feature the key must be properly cut and programmed. This service can be provided by a licensed auto locksmith or a dealer for cars. The first step to reprogramming a transponder is to make sure that the key is equipped with an electronic circuit board or transponder of the correct type. The key should be compatible with the onboard computer of the vehicle and have a keyring that is correctly positioned around the ignition barrel. This type of reprogramming is usually done with the transponder cloning machine which is able to copy a specific circuit board or transponder. Certain key blank manufacturers as well as experts in reprogramming provide this equipment. The cloning machine should be able to read the information transmitted by each transponder that is being cloned. Some cloning devices are upgradeable and are able to copy the most recent transponders that are being released. A locksmith who provides transponder key reprogramming services will also have the necessary tools to make sure the new key is cut. They can supply an alternative key that has an authentic transponder or generic key that works on the vehicle. They can also assist the customer in purchasing the right blank key. Transponder keys are a very crucial element of the safety and security features in modern vehicles. They are designed to stop hot-wiring which is a typical method of theft used by thieves to take cars. This is because the transponder chip makes it almost impossible to start a car without a proper key. A professional automotive locksmith can install a transponder chip, and then program it to the vehicle so that it can be started. PIN Codes PIN codes can be utilized in many ways to protect private data from physical and cyber 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 and users. Many automakers are needing keys to transmit not just the transponder's number but also the unique VIN number. These additional security measures require special key programming procedures that are often not available to independent mechanics unless they are able to access an exclusive tool for dealers like Autel's IM608 Immobilizer Scan Tool or Launch Tech's immobilizer scanner. When programming a new key it is crucial to choose the right PIN that is easy to remember, but is difficult for others to figure out. For this reason, most experts suggest using an assortment of letters and numbers. Avoid using personal information like birth dates, phone numbers, or social security numbers. They can be easily identified. To ensure your security make sure your PIN is at least six digits in length. This will make it more difficult for hackers to brute-force guess your PIN. However, there are technologies which can overcome this. Data Transfer Data transfer creates two persistent copies of the data -one at the source and the other at the destination. If the destination does not require an existing copy of the data, this may not be a problem – but it can be in the event that the data is evolving or needs to be updated frequently. In the ideal scenario, a copy of the data should be destroyed after it's no longer needed. In some instances, a data transfer can involve a third party – such as an IT department or cloud service provider. In this instance, it's important to understand who is responsible for overseeing the transfer process and the data involved. This will help prevent any issues that might result from unauthorised access to data or corruption. Key programming can be a valuable tool for auto repair shops, however there are limitations that technicians must be aware of. First, Putrino said that a shop must obtain an ID for locksmiths (LSID). This credential gives technicians secure access to the vehicle's immobilizer and PIN codes by using the National Automotive Service Task Force's Secure Data Release Model. Other factors to consider is ensuring that the shop has the proper scanners to handle the process. These scan tools will have to be able to harvest the PIN code from the modules, and allow technicians to program new keys. Many OEMs also require that the key transmit more than just its ID code. VW, Chrysler, and other companies require that the key transmit the unique VIN number of the vehicle. These additional transmissions are programmed using a an instrument for key programming. Many technicians don't provide key programming, but those who do can make an impressive amount of money. If you are a shop looking to get started, Putrino recommended considering a professional key programming tool, such as the XTool USA AutoPro Pad. This tool can perform many functions including EEPROM read and write BMW CAS3/2 key learning, remote learning for Mercedes Benz FEM, and more.
