Issue & Fix: During a Mercedes-Benz EIS key cloning job with Autel MaxiIM IM508S, the device displayed the error message: “Failed to acquire data. Please try again!” at Step 4 and did not show the password write step. In this case, the issue was caused by using a replacement key instead of the original key. The fix is to enter Expert Mode and obtain the password through: Expert selection → Get password → Add key/All key lost.
Technical Explanation
The customer's key was not the original key but a replacement key, which caused an identification anomaly during the operation.
Diagnostic / Action Steps
- Enter Expert Mode on Autel IM508S.
- Select Get password.
- Choose Add key/All key lost to acquire the password.
Final Result
After obtaining the password through Expert Mode, the Mercedes-Benz EIS key cloning procedure can continue.
