The Basics of Key Programming It's not as simple as it may seem. In reality, it's a thing that most people will end up going to the dealer or a locksmith to get. With the right equipment, brick and mortar parts departments can handle key programming. This article will go over some of the fundamental concepts of key coding so that you can start. Modern Vehicles Modern cars make use of a variety 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 is an essential component of automotive industry, as it ensures that these devices work correctly. In the past, cars relied upon simple metal keys to unlock their doors and start their engines. Keys like these were easy to copy and were easily stolen or lost. The majority of vehicles include key fobs with transponders inside. These chips are used to connect the key to the car's security system to ensure that only the right person can open and begin the vehicle. This is important as it makes it much more difficult for thieves to steal cars, and also allows owners to easily replace keys that have been damaged or lost. Many modern vehicles also have built-in security features that prevent them from starting unless the right key is present. These security features are an excellent method of keeping cars safe from theft, however, they also require people take the time to learn how to program their 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 scenarios: You may be able to help a client who has trouble starting their car. This issue usually occurs when the remote or key control isn't programmed correctly. This issue can be solved by using a key programing tool that is compatible for the model of your vehicle. You might also need to perform this procedure in the event that you're adding an additional key to your vehicle. The majority of modern vehicles allow the addition of a key through onboard key programming. This process utilizes a special scan tool to read the unique ID in the new remote or key and then transmit the information to the vehicle's computer. Some of the most popular programming tools are bidirectional, allowing data to be transferred between two vehicles. This is especially useful when an element needs to be replaced or flashed. This is important because it can save you time and money by decreasing the amount of time it takes to wait for the correct component to arrive from overseas. Transponder Chips A lot of modern cars have transponder chips that communicate with the car's computer system. When a key is placed into the barrel of ignition, the chip sends a signal that contains an encrypted digital code that identifies it as a genuine car key. This technology adds an additional layer of security for modern cars and helps to reduce the chance of theft. However, to take advantage of this added security feature the key needs to be cut correctly and programmed. This service is offered by a licensed auto locksmith or dealer. The first step in the reprogramming of a transponder key is to make sure that the key's blank contains the correct circuit board or transponder. The key must be compatible with the vehicle's onboard computer and have the key ring placed correctly around the ignition barrel. This kind of reprogramming is typically done using a transponder cloning machine, that can copy a particular circuit board or transponder. Some of the major blank manufacturers as well as experts in reprogramming offer this device. The cloning device should be capable of reading the data that is being transmitted on each transponder that are being cloned. Some cloning devices can be upgraded and can be used to copy the latest transponders that are being released. A locksmith who offers transponder key programming services will also have the tools to make sure the new key is properly cut. They can supply an alternative key that has authentic transponders or a generic key that can be used on the vehicle. They can also assist customers in purchasing the right blank key. Transponder keys play an essential part in the safety and security of modern vehicles. They are designed to stop hot-wiring, which is a common method used by thieves to take vehicles. This is because the transponder chip makes it almost impossible to start a vehicle without a key. A professional locksmith can install a transponder chip and program it into the car so that the car can be started. PIN Codes PIN codes can be utilized in many ways to safeguard private information from cyber and physical attacks. A PIN code is a sequence of numbers, typically four or six digits, that is required to authenticate transactions using banking systems and other card-based devices, governments with citizens, enterprises with employees, and computers with users, among others. Many car manufacturers are requiring keys to transmit not just the transponder's number but also the vehicle's unique VIN number. These additional security measures often require special key programming procedures which are not accessible to independent mechanics, unless they have access to a dealer only tool like Autel's IM608 immobilizer scan tool or Launch Tech’s XProg3 scanner. When programming a new key it is crucial to choose a PIN that is easy for you to remember however, it is difficult for anyone else to guess. Most experts suggest a combination of letters and numbers. Avoid using personal information such as birthdates, phone numbers or social security numbers. They can be easily deduced. To ensure your security ensure that your PIN has at least six digits in length. This will make it harder for hackers to brute force to guess your PIN, though there are techniques that can beat this. Data Transfer Data transfer creates two persistent copies of the data — one at the source and the other at the destination. This isn't an issue when the destination doesn't require a copy of the data. However, it can be an issue if the data is changing or needs to be updated continuously. In the ideal scenario, a copy of the data should be destroyed after it's no longer needed. In automotive key programming , the transfer of data may involve a third party – such as an IT department or cloud service provider. In this scenario, it's important to understand who is responsible for overseeing the process of transfer and the data involved. This will help prevent any issues that may arise from data access that is not authorized or corruption. Key programming is an excellent tool for auto repair shops, however there are some limitations that technicians need to be aware of. For starters, Putrino said that a shop must obtain a locksmith ID (LSID). This credential permits technicians to access the vehicle's PIN code and immobilizer codes by using the Secure Data Release Model of the National Automotive Service Task Force. Also, ensure that the shop has scanners that can handle the process. The scanners will require to retrieve the PIN code from the modules, and allow technicians to program new keys. Furthermore, many OEMs require that keys communicate more than its 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 with an instrument for programming keys. Many technicians don't provide key programming however, those who do can make lots of money. Putrino recommends that shops who are planning to start an enterprise consider using a professional key programmer like the XTool America AutoPro pad. This tool can perform a variety of functions including EEPROM read/write and BMW CAS3/2 Key Learning remote learning for Mercedes Benz, and more.
