Why we say this up front
Many landing pages bury pricing until the last click. We don't.
There is no stable, ethical way to hand out unlimited free SFD unlock tokens: each unlock ties to a unique ECU challenge and a cryptographic or supplier-backed response.
What SFD protection does
Schutz Fahrzeug Diagnose (SFD) locks sensitive coding on modern VAG ECUs until an authorised unlock token is applied.
Your scan tool reads an offline challenge from the ECU. A third party (like sfdcode) returns the matching unlock token. You write it back — then coding adapts and calibration channels open normally.
Why "free unlock" searches rarely pan out
SFD responses are computed through secured pipelines that cost money to operate and audit.
SFD2 is worse for "free" promises — tokens are brokered manually within a supplier network. Anyone claiming infinite gratis SFD2 tokens is probably misleading you.
We charge transparent per-unlock prices so support, uptime and refund policies stay real.
What you get when you pay
A token scoped to your module's challenge — delivered fast for SFD (typically under a minute) or within the published SLA for SFD2 manual delivery.
You also get receipt-friendly documentation for your workshop records.
