This is a powerful suite of specialized PIN code calculators for the Nissan NATS (Nissan Anti-Theft System). This collection is not a single application, but a set of tools designed to extract the immobilizer security PIN code from different types of control units found in Nissan vehicles. The PIN code is required for programming new keys. These tools work by reading the printed information directly from the module's label.
Tool 1: NATS Siemens IMMU Calculator
This calculator is designed for the common Siemens Immobilizer Control Unit found in many Nissan models.
How to Use:
• Locate the Siemens Immobilizer Control Unit in the vehicle.
• Find the required information on the unit's label, as shown in the program's example image.
• Select the "Country Code" (Made in Mexico, Germany, or Europe).
• Enter the "Date Code" from the label.
• Enter the "Encrypted PIN" from the label.
• Click "Submit" to calculate the final PIN Code.
Tool 2: NATS P12E-N16E SEC-E Calculator
This calculator is for specific models, such as the P12 Primera and N16 Almera, which use a different module for storing immobilizer data.
Critical Difference:
• As the tool's instructions state, "On P12 model, the label, showing the DATE CODE and ENCRYPTED PIN is located on the Smart Entrance Control unit(SEC-E), NOT on the Immobilizer Control Unit as with other models".
How to Use:
• Locate the Smart Entrance Control unit (SEC-E).
• Enter the "Date Code" from the SEC-E label.
• Enter the "Encrypted PIN" from the SEC-E label.
• Click "Submit" to calculate the final PIN Code.
System Compatibility
This software has been fully tested and is confirmed to be working perfectly on Windows 10 LTSC (2019).
