A Proprietary System With a Named Expiration Date
In brief: Volkswagen Group's own proprietary digital access system, GeKo (Geheimnis und Komponentenschutz), controlled which independent workshops could replace control units, program keys, or clear security-related battery pyrotechnic interlocks on VW Group vehicles. On March 31, 2026, that system was terminated.
What Replaced It
European type-approval rules under Regulation (EU) 2018/858 establish statutory access rights to Repair and Maintenance Information, operationalized in Germany through the SERMI scheme, which went live on April 1, 2024, following accreditation of inspection agency SERMA GmbH by the German National Accreditation Body (DAkkS). SERMI replaces proprietary OEM authorization tokens with a single digital certificate verifying the clean legal standing and technical credentials of the workshop and technician.
Why the 24-Month Gap Between the Two Dates Matters
The standardized system went live first. The proprietary one didn't disappear overnight.

SERMI's activation and GeKo's termination weren't simultaneous — there was a genuine 24-month transition window between the two. That gap gave independent workshops time to secure SERMI accreditation before losing whatever access they'd previously negotiated or worked around under the older proprietary system, rather than facing an abrupt cutoff with no standardized alternative in place yet.
What This Specifically Unlocks
With GeKo terminated, SERMI accreditation is now mandatory, not optional, for any independent workshop performing security-related repairs on Volkswagen Group vehicles specifically — replacing control units, programming keys, or clearing battery pyrotechnic interlocks. Workshops without SERMI accreditation lose the ability to perform these specific repair categories on VW Group vehicles entirely, not just face a competitive disadvantage against dealerships.
A Named Comparison: Why This Deadline Is More Concrete Than Most Regulatory Milestones
Many regulatory transitions in this market involve gradual enforcement, phased compliance windows, or discretionary interpretation. GeKo's termination is different: it's a specific corporate system shutdown with a fixed date, not a regulatory enforcement ramp-up. That makes it one of the more genuinely trackable, binary milestones in the German EV repair landscape — workshops either had SERMI accreditation in place by March 31, 2026, or they lost access to a defined category of VW Group repair work on that exact date.
Why Other OEMs Are Likely Watching This Deadline
Volkswagen is Germany's largest domestic manufacturer, and its transition provides a genuinely concrete precedent other OEMs operating proprietary access systems in the German market can study directly -- both the 24-month runway it provided and the hard cutoff it eventually enforced, rather than an indefinite grace period.
What This Means for Independent Workshops
The practical takeaway: any independent workshop servicing Volkswagen Group vehicles that hadn't secured SERMI accreditation before March 31, 2026 has already lost a defined category of repair capability, not merely a competitive edge — and workshops planning to service other manufacturers' vehicles should watch for similar proprietary-system termination dates as OEMs across the market align with the same standardized framework.
