Dealer vs Local Mercedes Auto Locksmith
Main dealers can be excellent but often require towing and waits for parts or workshop appointments. A mobile Mercedes locksmith can often:
- Reach you quickly anywhere in Slough or the SL postcode area
- Provide same-day key cutting and programming in many cases
- Help when you’ve lost all keys, without needing the vehicle transported
- Offer a convenient, cost-effective alternative to dealer key replacement
If you’re comparing options, our pricing page explains cost factors without fixed price lists and helps set expectations.
Common Mercedes Key and Lock Questions
Can you make a Mercedes key without the original?
Yes. With proof of ownership, we can create a new key and programme it to your Mercedes using dealer-level diagnostics. For some models, advanced EEPROM or immobiliser work may be required, which we handle on-site wherever possible.
My Mercedes says “Key Not Detected.” What should I do?
First, try a known-good spare if you have one and check the fob battery. If the message persists, the issue may be with the key, the vehicle’s receiver, or the immobiliser system. We can diagnose and resolve these faults with specialist tools.
How long does Mercedes key programming take?
Many jobs are completed during a single visit. Time varies by model, key type (smart/proximity vs. standard remote), and whether all keys are lost. We’ll give you an accurate timeframe when you call.
Will you damage my Mercedes when unlocking it?
Our approach is non-destructive wherever possible. We use specialist lock-picking and decoding tools designed for vehicle locks. In rare cases of severe lock failure, we will explain options and get your approval before proceeding.
Can you programme a used Mercedes key fob?
In most cases, used Mercedes fobs cannot simply be “reprogrammed” because they’re coded to another vehicle or have locked crypto. We can supply and programme the correct new or virgin key types suitable for your model.
Do you cover Mercedes vans like Sprinter and Vito?
Absolutely. We regularly assist with Sprinter and Vito keys, programming, lockouts, and ignition issues for business and fleet users across Slough.
