For 2003 Mercedes ML350 All Keys Lost,how to solve?

Avdi can learn the key or remove the eam module read eeprom with orange5 and write it by tango…

You can read mcu with Orange5

And then you can make transponder with Tango or TM100.

And just write on chip pcf7935

Read it with orange5

Mercedes all keys lost best solution: VVDI MB Tool

Vehicle coverage:

Time for data acquisition:

Lost all key data acquisition time depends on EIS type, It needs about 3.5-8 minutes

W204, W207 lost all key data acquisition require 2 hours and 10 minutes

W216, W164 2009- lost all key data acquisition require 2 hours

Lost all key calculate time in server: 30 seconds – 1 minute

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

Possible to OBD unlock Simos PCR 2.1 with Kess V2 clone?

Look here: all information can be found here to help you unlock PCR 2.1 using Kess v2 china clone.

Connection:

ECU connection for the bootmode unlocking procedure only!

Wiring diagram:

Test:

Basic info:

Tested and confirmed working by me on 4 ecus /cars

only on Chinese clone not reworked unit: ktag 6.070, kess v2 v4.036, ksuite up to 2.15

Tips and guides of tools for use:

pcr 2.1 need to be as you know unlocked before writing .

On this ecu pcr 2.1, ksuite (kess v2 or ktag) seem to be more stable than fgtech on pcr but work too sometimes: i get error with fgtech on one pcr2.1 but no problem with ksuite . 

So if you have both tools , prefer ksuite seem to be more stable & flawlessly and car run ok .

After you get you ecu unlocked in boot mode , with fgtech just remove boot and left pin connection , and read or write on bench .

On ksuite tools , you can’t read or write with ktag , only unlock . (alientech need to work on it…)

with kess it’s ok , BUT , you can’t use the tricore module !

The problem is that the harness is plugged in the tricore module . so you have to build your own bench cable : just get a obd female plug on a scrapyard , and wire +12 gnd and can h/l (kline is not used but you can wire it it will make a universal bench cable) .

The trick to get communication error free on both fgtech and kess cable is to use a strong external psu .

when the tool id or read or write the ecu , the ecu will perform a kind of reset , and the big cap inside the ecu will go charging , causing a drop in voltage if your psu isn’t strong enough to handle it . THAT WILL CAUSE THE COMM ERROR . That’s the only thing you have to take care . 

when i made test with many little psu (like one you get with your tools) i have seen 7 volts drop some time , so the ecu is shutting down and no comm . 

you can use computer atx psu modded to work on bench (green wire plugged on ground to power on ) i think anything that can provide +12v 2A will be ok . i didn’t need more than 12v just a stable 12V . 14v unstable will not be ok 

that’s why on the car you have no problem , car battery can handle the cap charging current .

There is no immo caused comm error on this ecu , psu is the problem !!

So in conclusion : good psu and obd home made bench cable , remove tricore module on kess = 100% tested bench flashing solution for pcr2.1 .
