Zed-Full Mercedes Benz IR Sniffer Key To Collect Data From EIS / EZS – ZFH-MB

The Zed-FULL Mercedes Benz IR Sniffer Key (ZFH-MB) is a specialized accessory used in Mercedes key programming systems.

 What it is

It is a “sniffer” device in key form designed to collect encrypted ignition data directly from the vehicle’s EIS/EZS (Electronic Ignition Switch) system.

What it does

When inserted into the ignition (or used in IR-prog workflow depending on model):

• Reads/“sniffs” communication between key and EIS/EZS
• Collects key authentication data (IR data stream)
• Sends that data to the Zed-FULL main unit
• Helps calculate or generate a new working key
