- Come to you the same day or promptly at a convenient time
- Open the vehicle non-destructively in most cases
- Cut and program a working key or smart key on site

Helpful Tips for Mercedes Owners
- Keep a working spare: A programmed spare key can save time and money if the main key is lost or fails.
- Watch for early signs: Reduced remote range or intermittent “Key Not Detected” can signal a failing key or aerial. Early diagnosis is cheaper than an emergency.
- Protect from moisture and impact: Smart keys and fobs can be sensitive to water and drops. A protective cover helps.
- If keys are stolen: Consider immobiliser reprogramming and key deletion to prevent old keys starting the car. We can advise and act quickly.
FAQs
Can you make a Mercedes key without the original?
Yes. With proof of ownership, we can create and program a new Mercedes key even if you’ve lost the original. We use dealer-level diagnostics, OBD2, and in some cases EEPROM programming to pair the new key to your immobiliser.
Will you damage my Mercedes when unlocking it?
We prioritise non-destructive entry methods wherever possible, protecting your locks and seals. In rare cases where a different method is needed, we’ll explain why and obtain your approval before proceeding.
How long does Mercedes key programming take?
Most jobs are completed in one visit. Times vary by model and whether all keys are lost, but many replacements and programming tasks are finished the same day we attend.
Do you cover Mercedes vans like Vito and Sprinter?
Absolutely. We provide van and commercial locksmith support for Vito, Sprinter, V-Class and more, including fleet solutions and spare key creation for business continuity.
Can you fix “Key Not Detected” on push-to-start models?
Yes. We diagnose whether the fault is with the key, the vehicle’s aerials, the steering lock, or the immobiliser system. We’ll then repair or program as needed to restore reliable starting.
What affects the price for a Mercedes key?
Costs depend on model, year, key type (remote vs smart), whether you have a working key, and the time of call-out. We’re transparent on costs—contact us for a free, accurate quote.
