This is important because it will save you time and money by decreasing the amount of time spent waiting for the right part to arrive from overseas. Transponder Chips Many modern vehicles have transponder chips which communicate with the computer system of the car.

This technology adds an extra layer to modern cars and lowers the risk of theft. However, to benefit from this added security feature the key must be properly cut and programmed.

The key must also be compatible with the vehicle's on-board computer and include the key ring properly positioned around the ignition barrel. In the majority of 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 important blank manufacturers as well as experts in reprogramming. The cloning machine should be able to read the information sent by each transponder that is being cloned. Some cloning devices can be upgraded and can be used to copy the latest transponders that are being released.

PIN Codes PIN codes can be utilized in many ways to protect private data from cyber and physical attacks. A PIN code is a sequence of numbers, usually with four or six digits that is used to authenticate transactions using banking systems and other devices that use cards, government agencies with citizens, businesses with employees, and computers with users, among others. Many automotive manufacturers are now asking keys to transmit not only the transponder code but also the unique VIN number. These additional security measures require specific key programming procedures that are often 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 important to select an encryption method that is simple for you to remember however, it is difficult for anyone else to guess.

Ideally, one copy of the data should be discarded after it's no longer needed. In some instances data transfers could involve a third party like an IT department or cloud service provider. In this scenario it is crucial to identify who is responsible for managing both the transfer process and data in question.

Key programming is an excellent tool for auto repair shops, but there are limitations that technicians must keep in mind. To begin, Putrino said that a shop will need to procure an ID for locksmiths (LSID). This credential allows technicians to access the vehicle's PIN codes and immobilizer code using the Secure Data Release Model of the National Automotive Service Task Force. Other considerations include ensuring the shop has the proper scanners that can handle the process. The scanners must be capable of extracting the PIN code directly from the modules and permitting technicians to program a new keys. Many OEMs also require that the key transmit more than just 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 by using a special key programming tool.
