Modern Mercedes vehicles use sophisticated keyless entry and push-start systems. If your smart key stops working, we can reprogram or replace it using dealer-grade diagnostic software, restoring full locking and ignition functionality.

In "all keys lost" cases, we securely remove old key data from your car's ECU to prevent unauthorized access.

🔧 Lost or Broken Mercedes Key Solutions

If your key has snapped, been stolen, or stopped working, we can extract broken key fragments and cut and program a new one on-site.

Our mobile vans are fully equipped for roadside, home, or workplace service across Basingstoke and nearby areas — handled only by trusted DBS-checked locksmiths.

🎯 ADAS Calibration (Advanced Driver Assistance Systems)

Modern Mercedes models rely on precision sensors and cameras for safety. After windshield replacement, ECU work, or collision repair, your ADAS may need recalibration.

We use certified equipment to align sensors and cameras to manufacturer standards, keeping your vehicle's safety systems accurate and dependable.
