Key Solutions

Our Key Services

From emergency all-keys-lost situations to adding convenience features — complete key solutions for modern Mercedes-Benz vehicles.

All Keys Lost (AKL)

Completely lost every key? We can generate new keys from scratch using your vehicle's immobilizer data. This service requires proof of ownership and valid ID. Available as mobile service or at our workshop.

  • Full immobilizer data extraction
  • New genuine key generation
  • All existing keys deleted for security
  • Same-day service in most cases

Spare Key Programming

Need an extra key? We program a genuine Mercedes-Benz key to your existing immobilizer system. You supply the key or we source it for you. Perfect for families or as a backup.

  • Program up to 8 keys per vehicle
  • Genuine Mercedes key blanks
  • Remote and keyless function sync
  • Full testing before handover

Keyless-Go Activation

Add keyless entry and push-button start to cars that already have the hardware fitted from factory but were not enabled at purchase. Common on lower trim levels.

  • Hardware presence verification
  • Software activation only
  • Hands-free trunk included
  • No physical changes needed

Emergency Key Cutting

Physical blade cutting for emergency manual entry. Even with keyless-go, every Mercedes needs a mechanical backup. We cut blades to factory specifications.

How It Works

Our 4-Step Process

Secure, transparent, and fully documented from start to finish.

Verify Ownership

We require proof of ownership and valid photo ID before any immobilizer work. This protects you and us.

Read Immo Data

We extract immobilizer data from your vehicle using dealer-grade tools. This is done securely and never stored.

Generate Key

Using your immo data, we generate a fully synchronized genuine Mercedes key with all functions enabled.

Test & Handover

Every key is tested for lock, unlock, start, remote, and keyless functions before we hand it over.

Lost Your Keys? Don't Panic.

We resolve all-keys-lost situations same day in most cases. Mobile service available — we come to your location.
