Unlock SFD

Each unlock costs 1 prepaid token. SFD1 is instant; SFD2 is queued for operator delivery.

When validation passes, we deduct credits for the selected generation (demo: on submit). Production will debit only after the proxy reports a successful upstream unlock.

Unlock parameters

Enter your control-module hex address and paste the offline SFD challenge from your workshop diagnostic tool.

Hex address of the ECU.

We accept spaces, dashes, lowercase — we normalize it for you.

Tip: upload a screenshot or photo of the QR shown by your scan tool — we decode the offline challenge for you.
