Programming a new key for a 2011 Mercedes ML350 (W164) is a common challenge that can be solved quickly with the Autel MaxiIM IM508S & XP400 Pro programmer.
This professional setup allows you to calculate the vehicle password and write a new functional key without dealer-level tools. Whether you are fixing a non-working fob or adding a spare, this streamlined guide covers the essential “Smart Selection” workflow.
Preparation:
Success in Mercedes key programming depends on stability. Before starting, ensure:
- Device Link: Connect the IM508S to the XP400 Pro Programmer.
- Power: Maintain consistent vehicle voltage and a stable internet connection.
Simplified Programming Steps
1. Identify & Detect
Select Immobilizer > Mercedes-Benz > Smart Selection > Add key > On vehicle
The IM508S will automatically detect the W164 chassis. The system will then check the frequency of both your original key and the new blank key to ensure compatibility.
2. Password Calculation
This is the “fix” for missing security data. Follow the on-screen prompts to:
- Insert the original key into the EIS (Ignition) and the XP400 Pro as directed.
- The tool will automatically communicate with the vehicle’s anti-theft system to extract the necessary password.
3. Writing the New Key
Once the password is calculated, the system generates a key file. Insert your blank key into the XP400 Pro programmer. The IM508S will write the data, completing the process in seconds.
The Result: A Fully Functional Fix
After programming, verify the “fix” by testing all features:
- Ignition: Confirm the engine starts with the new key.
- Remote: Test Lock, Unlock, Trunk, and Panic buttons.
