Review of VVDI Mercedes all key lost:
made W207 all key lost with VVDI MB. Work perfect, great tool!!
made all keys lost W906 successfully! Just remove EZS, open it, read MCU (0L01Y is there I think) EEPROM, save dump and calculate keys. It’s easy to do it!
Tested W212 all Keys lost OK with VVDI MB tool. Got a W212 EIS to make a key, it needs 2 tokens, one free one paid money.
W209 or W211 all key lost for me is easy to do with VVDI.
W204 W207 all key lost tested ok, get Password from W204 EIS successfully in second attempt, first time failed.
W212, W166 and W256 all key lost are possible for VVDI.
W166, W246, W212, W212 FBS3 all key lost OK
do W221 all key lost last month with VVDI MB TOOL and a second hand EIS W221 lock with a key
