If your business works with vehicle security, from immobiliser coding, module repairs and programming or work on any security related components, including diagnostics on security-related systems, SERMI certification is about to become essential.
This new, EU-backed initiative will soon redefine how workshops, technicians, and repairers access secure vehicle data. Staying informed and prepared will be key to maintaining your competitive edge in the evolving automotive industry.
SERMI stands for Security-related Repair and Maintenance Information. It’s a new European standard designed to ensure that only verified and certified professionals can access sensitive vehicle security information. This includes access to key programming, anti-theft systems, and other security-related modules.
A SERMI certificate is a unique, personal digital credential that grants authorised access to vehicle manufacturers’ security systems. With a single, standardised registration, SERMI removes the need for multiple accreditations from individual OEMs, streamlining the process for independent repairers and specialists while ensuring a high level of trust and data protection across the industry.
Once fully implemented, only SERMI-certified individuals and businesses will be able to perform diagnostics or repairs on security-related vehicle systems. Without certification, access to critical data and components will be restricted, making it essential to get certified early and stay compliant.
