Electric and hybrid Mercedes-Benz vehicles feature complex immobiliser systems and keyless entry protocols to protect against unauthorised access. AT Technicians offers advanced support for key programming and immobiliser-related faults using OEM diagnostics and encryption tools. Whether you’ve replaced a key, installed a new ECU, or are facing start-up failure due to security lockouts, our technicians can help. We use Xentry and coding tools to synchronise new keys, clear invalid entries, and restore secure communication between modules. For push-start models and digital key systems, we also update keyless-go parameters. We work closely within data security regulations, ensuring all programming is legal, encrypted, and logged. Faulty immobiliser modules are identified, tested, and replaced if needed. We also reset theft-attempt flags and align immobiliser functions with the latest software versions. Restore confidence in your vehicle’s security. Book immobiliser and key support today with AT Technicians your trusted expert in electric Mercedes-Benz diagnostics.
