This is particularly useful when a module has to be replaced or flashed. This is important as it can save you time and money by cutting down on the time you wait 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. The chip transmits a digital code when the key is inserted into the ignition barrel. This unique code identifies the key as a genuine key. This technology adds an additional layer of security for modern vehicles and reduces the risk of theft. To make the most of the added security feature on a car, it is essential to have the key properly cut and programmed. This service can be provided by a certified auto locksmith or a dealer for cars. The first step in reprogramming a transponder is to ensure that the blank key has an electronic circuit board or transponder that is of the proper type. The key should also be compatible with the vehicle's on-board computer and have the key ring properly positioned around the ignition barrel. In the majority of instances, this kind of reprogramming requires the use of a special transponder cloning device, which can duplicate a specific transponder or circuit board. This equipment is available from key blank manufacturers and some reprogramming specialists. The cloning device must be able read the data sent by the transponder which is being copied. Some cloning devices can be upgraded and can be used to copy the most recent transponders that are released.

A professional locksmith can install the transponder chip and program it into the car so that it can be started. PIN Codes PIN codes are utilized in various applications to ensure that private information is safe from physical and cyber-physical attacks. A PIN code is generally an eight-digit or six-digit sequence of numbers used to authenticate transactions between banks and other devices for credit card as well as between citizens and governments as well as employees and businesses as well as computers and users. Many car manufacturers are asking keys to transmit not just the transponder's code, but also the unique VIN number. These additional security measures often require special key programming procedures which are not available to independent mechanics unless they have access to a dealer-only tool such as Autel’s IM608 immobilizer scan tool or Launch Tech's XProg3 scanner. When programming a new key, it is important to select a PIN that is easy for you to remember but is difficult for others to figure out. Most experts recommend using a combination of letters and numbers. Avoid using personal information, such as birthdates, phone numbers or social security numbers. They can be easily guessed. For the most protection, use a PIN that has at least six digits in length. This makes it more difficult for hackers to brute force to guess your PIN, though there are technologies that can beat this. Data Transfer Data transfer results in a pair of persistent copies one at the origin and another at the destination. This may not be an issue if the destination doesn't require a copy of the data. However, it can be a problem if the data changes or needs to be continuously updated. In the ideal scenario, a copy of the data should be discarded after it's no longer needed. In some instances the transfer of data may involve a third party such as an IT department or a cloud service provider. In this scenario it is crucial to know who is responsible for overseeing the process of transfer and the data being transferred. This will help prevent any issues that might arise from unauthorized data access or corruption. Key programming is a valuable tool for auto repair shops to have in their arsenal, but there are certain limitations that technicians must keep in mind. Putrino explained that the first step is to obtain an ID for locksmiths. This credential allows technicians to access the vehicle's PIN codes and immobilizer codes by using the Secure Data Release Model of the National Automotive Service Task Force. Also, make sure the shop has scanners that can handle the process. The scanners require to harvest the PIN code from the modules, as well as allow technicians to program new keys. In addition, a lot of OEMs are requiring that the key transmit more than just its ID code. VW, Chrysler, and other manufacturers require that the key transmit the VIN number unique to the vehicle. These additional transmissions are programmed with a special key program tool. Key programming is a difficult procedure that not many technicians offer, but it can be a lucrative career for those who do. If you are a shop wanting to get started, Putrino recommended considering a professional key programming tool such as the XTool USA AutoPro Pad. This tool can perform many functions that include EEPROM read and write, BMW CAS3/2 key learning remote learning for Mercedes Benz FEM, and more.
