Programming & Coding

We provide dealer-level programming and coding for most makes and models. Whether you’ve replaced a part, updated your ECU, or need specific functions enabled or disabled, our technicians use genuine diagnostic tools to ensure everything runs perfectly.

Key Replacement

Lost or damaged your car key? Our key replacement service offers fast and reliable solutions. We can cut and program new keys or reprogram existing ones on-site — saving you the hassle and expense of visiting a dealership.

DPF Cleaning

Our DPF cleaning service helps restore your diesel particulate filter to full efficiency. We use professional-grade equipment to remove built-up soot and ash, improving performance, reducing emissions, and preventing costly engine damage.

Dealer Diagnostics

We use the same diagnostic technology as main dealerships to accurately identify and resolve issues with your vehicle. Our dealer diagnostics provide a full picture of your car’s health, ensuring you only pay for the repairs you need.
