Car Diagnostics
Our comprehensive diagnostic service identifies electronic system faults using dealer-level equipment. We analyse engine management, airbag, ABS, and immobiliser systems, providing printed fault code reports with plain English explanations. Follow-up scans are included free within our service pricing, ensuring complete fault resolution for both minor warning lights and complete vehicle non-starts.
Key Programming
We supply and program all key types including smart keys, flip remotes, and slot-in dash keys. Our CNC key cutting equipment produces precision cuts while maintaining security coding. Emergency lockout services enable same-day key replacement without vehicle recovery. Postal key programming options available for customers unable to visit our Norwich workshop.
ECU Programming
Specialist ECU cloning transfers vehicle data to secondhand units, costing approximately 20% of dealership replacements. We perform immobiliser deletes, DPF/EGR removals, and performance remapping. Our stock includes thousands of pre-programmed ECUs with next-day UK delivery. Virginising services enable secondhand ECUs to self-code to vehicle systems.
Cluster Repairs
We repair digital instrument clusters and correct mileage discrepancies caused by voltage surges or component failures. Our cloning service transfers immobiliser data between faulty and replacement clusters without requiring PIN codes. Specific solutions available for Audi TT, VW/Audi/Seat/Skoda models, and Renault Megane MK3 systems.
Mobile Services
Our mobile technicians provide key programming and diagnostic services at customer locations throughout Norfolk and North Suffolk. Available until late seven days a week, we handle lost key situations without vehicle damage. This service avoids recovery costs while maintaining the same technical standards as our workshop operations.
