SERMI (Secure Repair and Maintenance Information) is a European-wide certification scheme that controls access to security-related vehicle data such as immobiliser codes, key programming, and anti-theft systems. Only vetted, approved businesses can legally access this information.

Yes. 125 Coding achieved official SERMI approval on 1st May 2026, alongside our existing credentials as an Authorised VW Group UK Independent Repairer and Porsche Partner Network member.

Any work that touches vehicle security systems — including key programming and replacement, immobiliser repairs, ECU coding involving security modules, and anti-theft system work. As regulations tighten across the UK and Europe, more services are falling under SERMI requirements.

While certifications like VW Group Authorised Independent Repairer or Porsche Partner Network cover technical competence and manufacturer access, SERMI specifically governs security data access. It involves criminal record checks, identity verification, and ongoing audits — making it one of the strictest certifications in the industry.

SERMI approval means your vehicle is being worked on by a vetted, background-checked professional with legitimate access to manufacturer security data. This protects your vehicle from improper coding, ensures insurance compliance, and gives you peace of mind that the job is done correctly and securely.
