How to submit a D1 form

D1 Customer Authorization Forms are a critical part of the NASTF verification process, used by Vehicle Security Professionals (VSPs) to prove vehicle ownership and obtain customer consent before accessing secure vehicle functions (e.g., key programming or system resets).

To create a D1 form:

1. Log in to the SDRM Registry and select D1 Forms from the menu.

2. Choose the correct form and begin with the Ownership Verification section, entering accurate vehicle and owner details.

3. You may save the form and return later.

4. After verifying customer and vehicle info in person, upload supporting documents and fill in the Service Performed section.

5. Submit the form to complete the process—it will automatically link to the proper OEM validation request.

If you have any further questions, please contact the NASTF support team at support.nastf.org.
