KEYS
A spare key for your Mercedes.
Key lost, broken or you’d like a spare? We make a replacement key for your Mercedes and program it to match your vehicle.
When you need us
- Key lost – only one or none left
- Key is faulty and no longer recognised
- You’d like a second or third key
- Bought a used car with only one key
- Remote control or key housing damaged
How it works
For a replacement key we need the VIN and proof that the vehicle is yours: registration document and ID card. Without this proof we don’t make keys.
Depending on the model we program the new key on the vehicle or via the electronic ignition switch (EZS). We tell you in advance whether the whole vehicle or just the ignition switch needs to come to us.
Focus on Mercedes-Benz. AEZ is an independent master workshop; brand names are used for description only. We tell you whether a repair is possible after testing.

Frequently asked questions
Is it possible if all keys are lost?
In many cases, yes. The effort is higher because the ignition switch (EZS) has to be included. We check this in advance using your VIN.
What do I need to bring?
Registration document, ID card and – if available – your existing key.
How much does the repair cost?
That depends on the unit and the fault. After testing we tell you the price – we only repair with your approval.
Can I send the control unit in?
Yes. After a quick chat, by DHL to AEZ, Werkstraße 4, 46240 Bottrop, Germany. Packing tips and the shipping note to fill in are on the “Sending in a control unit” page.
Do you only work on Mercedes-Benz?
Our focus is Mercedes-Benz. For other makes, just ask with the vehicle and part number – we’ll tell you honestly whether we can help.
