1998E300 key failure

[alaskajones]

Just a quick post about my 1998 E300 DT which had the smart key stop working, no door unlock and no reaction from electronic ignition switch. Fresh batteries in key, full vehicle battery charge, key led kit every time button was pressed, infrared was detected with phone camera.

Anywho, a new key solved the issue, and ~only~ cost me $417 ay our local Medford MB dealership.
