Topic: Is there any solution yet for W164 2007 all keys lost?
w164 has 2 types, Motorola based and nec based. as far as I know only Motorola based eis can be decoded. nec based eis has locked/ unreadable processor with city name mask i.e. Amazonas, sydney, etc. best solution for this is to replace eis and make ecu virgin then personalize and activate ecu with new( used) eis installed.
this Motorola MCU can be done for sure with AVDI, many other tools out there…
But EZS with NEC inside generation 2005-2007 with plugs far apart.
With AVDI from OBD usually, I go to the EZS actual values at the end of the table you will see if is NEC or HC12.
In my case was NEC inside so Iv got THIS VERSION IS NOT SUPPORTED.
W251 03/2009 NEC A1645451308 AKL success.
The very early W164 models have Motorola which you can read by an external programmer like vvdi, cgdi mb, smok, rosfar etc. Then there is EIS with NEC processor not Motorola and till 2007 it is not possible to do AKL, after 2007 it is possible.
How does VVDI MB tool program W164 after 2009 all keys lost
How does the CGDI MB program W164 2009 – AKL?
Here, I’d like to upload some info with part numbers and Photos of the 2 different types shortly.
Here is a photo with the 2 types:
