We are excited to share another successful Mercedes-Benz key programming case using powerful Xhorse KEY TOOL PLUS! This case highlights the tool’s capability to handle complex EIS/EZS cloning operations on older Mercedes models with confidence and precision.
Vehicle Details:
- Model: 2005 Mercedes S430
- Platform: W220 / W215
- ECU Type: EIS/EZS
- Processor: Motorola 4L40K
- Operation: Full EEPROM + Flash Read & Write
Summary:
Using VVDI KEY TOOL PLUS PAD, we successfully performed a full EIS/EZS clone procedure by reading and writing both the EEPROM and Flash memory—all without replacing the original module. This demonstrates the tool’s advanced support for Mercedes-Benz electronic systems, even in models with Motorola-based ECUs.
