Apex Auto Electrical has expanded its trade-only postal Mercedes EIS and EZS cloning service for UK auto locksmiths, garages and motor traders, offering part-number checks and 24 to 48-hour turnaround.
— CROOK, COUNTY DURHAM, United Kingdom – Jun 4, 2026 – Apex Auto Electrical, the trade-only automotive electronics workshop operated by Key Crafters Limited, has expanded its nationwide mail-in Mercedes EIS repair service for UK auto locksmiths, independent garages and motor traders. The Crook-based workshop accepts faulty Mercedes Electronic Ignition Switch modules and compatible donor units by tracked courier, then returns cloned or repaired modules after bench-level testing, subject to module condition and compatibility.
The service is designed for trade customers handling Mercedes-Benz non-start faults linked to EIS or EZS failure. These modules form part of the vehicle immobiliser system, managing key recognition, starter authorisation and related security data. When an EIS fails, the key may not be recognised, the vehicle may not start, or the steering lock may remain engaged.
Trade Mail-In Mercedes Support
Apex Auto Electrical provides mercedes eis repair, mercedes eis cloning, EZS cloning and mercedes immobiliser repair support across common Mercedes-Benz platforms, including C-Class, E-Class, M-Class, GLE, S-Class, Vito and Sprinter models from relevant production years. The workshop verifies part numbers before work begins and applies a no-fix-no-fee policy when a module cannot be successfully cloned.
“Mercedes EIS work can be one of the most expensive electronic faults an independent garage has to quote,” said John Yelland of Apex Auto Electrical. “A trade mail-in process gives workshops a practical way to send the module, confirm compatibility and receive a tested unit without moving the vehicle through a dealer route.”
The mail-in Mercedes EIS cloning service covers immobiliser data transfer, donor module preparation, dump-file work, all-keys-lost support and bench programming where applicable. Jobs are handled for business customers only, not retail consumers, keeping the process focused on auto locksmiths and garage workflows.
UK Coverage for Automotive Trade Customers
Apex Auto Electrical serves trade customers across County Durham, the North East and the wider United Kingdom by post. Modules arriving before 11am may be returned the same working day where possible, with most suitable work completed within 24 to 48 hours. Trade enquiries can include part-number checks, donor-unit questions and turnaround guidance before modules are shipped.
