The Basics of Key Programming It's not as easy as it appears. In fact, it's something that a majority of people end up going to the dealer or a locksmith for. Brick and mortar parts departments are able to code keys using the right equipment. This article will look at some of the fundamentals of key coding to get your shop up and running. Modern Vehicles Modern vehicles use electronic devices that communicate internally with the car. These systems include key fobs, as well as remote start systems. Vehicle key programming has become important to the automotive industry because it helps to ensure that these devices work properly. In the past, cars relied on simple keys made of iron to unlock their doors and start their engines. Keys like these were easy to duplicate of and could be stolen or lost. Now, most vehicles are equipped with key fobs with a transponder chip within. These chips are used to link the key to the car's security system, ensuring only the right person is able to open and start the vehicle. This is crucial because it makes it harder for thieves to steal a car and allows owners to replace a lost or damaged key easily. Many modern vehicles also come with security features that stop them from starting unless the right key is in place. These systems are great to keep your vehicle safe from theft. However they require that you learn how to program your keys correctly. If you're a locksmith or auto technician having key programming capabilities is a must. You may be required to perform this service in three different scenarios: You may be able to help a client who has trouble getting their car started. This is usually the case when the key or remote control isn't programmed correctly. This issue can be fixed with a key programming tool that is compatible with the specific model of the vehicle. This service could also be required if you are adding an additional key to your vehicle. Modern vehicles permit the addition of a key through onboard key programming. This process uses a scan tool to identify the unique identification in the new key or remote and transmit this information to the vehicle system. Some of the most popular programming tools are bidirectional, allowing data to be transferred 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 are equipped with transponder chips that communicate with the car's computer system. When a key is placed into the ignition barrel the chip sends a signal with an encrypted digital code that identifies it as a genuine car key. This technology provides an extra layer of security for modern vehicles and reduces the risk of theft. However, in order to take advantage of this security enhancement the key needs to be properly cut and programmed. A certified auto locksmith or dealership can provide this service. The first step in the transponder key reprogramming process is to ensure that the key blank is equipped with an appropriate type of circuit board or transponder. The key must be compatible with the onboard computer of the vehicle and include a keyring that is correctly placed around the ignition barrel. In most cases, this type of reprogramming requires the use of a special transponder cloning device that can copy a specific transponder or circuit board. This equipment is available from some major blank manufacturers as well as experts in reprogramming. The cloning device should be capable of reading the data that is being transmitted on each of the transponders that are being cloned. Some cloning equipments are upgradeable and can be used for copying the latest transponders. A locksmith who provides transponder key programming services will also have the necessary tools to ensure that the new key is properly cut. They can provide the replacement key using an authentic transponder or an equivalent one that will work for the vehicle. They can also assist customers in obtaining the correct blank key. Transponder keys are an crucial element of the security and safety features of modern vehicles. They are designed to avoid the hot-wiring of vehicles, which is one of the most popular ways thieves steal vehicles. The transponder chip makes it nearly impossible to start a vehicle without a key. A professional locksmith can install the transponder chip and program it to the car so that the car can be started. PIN Codes PIN codes can be utilized in a variety of ways to shield private data from physical and cyber attacks. A PIN code is usually a six-digit or four-digit sequence of numbers that is used to verify transactions between banks and other card devices as well as between citizens and governments employees, businesses and government officials as well as computers and users. A lot of automakers now require keys to transmit the VIN number of the vehicle, as well as the transponder code. These additional security measures need special key programming procedures, which are typically not available to independent mechanics unless they are able to access tools that are only available to dealers, such as Autel's Immobilizer Scan Tool IM608 or Launch Tech's X Prog3 immobilizer scanner. When programming a new key it is crucial to choose an encryption method that is simple to remember, however, it is difficult for anyone else to figure out. Most experts suggest a combination of numbers and letters. Avoid using personal information like birthdates, phone numbers or social security numbers. They are easily guessed. Use a PIN that has at least six numbers for the greatest security. This makes it harder for hackers to guess your PIN. However, there are technologies which can overcome this. Data Transfer Data transfer creates two persistent copies of the dataone at the source and another at the destination. This may not be an issue when the destination does not require an exact copy of the data. However, it could be an issue if the data changes or needs to be constantly updated. Ideally, one copy of the data should be destroyed after it's no longer required. In some cases data transfers could involve a third party – such as an IT department or cloud service provider. In auto key programmers , it's important to understand who is responsible for managing the transfer process as well as the data in question. This can help to prevent any issues that may result from unauthorised access to data or corruption. Key programming is a useful tool for auto repair shops to use, but there are some limitations that technicians should be aware of. For starters, Putrino said that a shop will need to procure an ID for locksmiths (LSID). This credential grants 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. Other things to consider is making sure the shop has the proper scanners to handle the process. The scanners need to be able to retrieve the PIN code from the modules, and also allow technicians to program new keys. In addition, a lot of OEMs require that keys transmit 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 using the key program tool. Key programming is a difficult process that many technicians don't offer, but it can be a lucrative venture for those who can. For shops looking to get started, Putrino recommended considering a professional key programming tool like the AutoPro Pad from XTool America. This tool is capable of a wide range of functions, including EEPROM read and write, BMW CAS3/2 key learning remote learning for Mercedes Benz FEM, and more.
