???MB ir Key the definitive guide???

[bonecrusher]

Hello Guys.
I have a customer whose IR key from a w202 is damaged(WATer).I have been going through all the threads here and cant seem to find a solution.What is the procedure to get this car back on the road and what tools do I need to buy,I know that I will need x-prog.I have bought a second hand key,what else do I need.Any help in the right direction will be appreciated.

Does anybody use this?

Not a problem mate, change the eeprom in the old and put in the new

[bonecrusher]

I have done this but it still does not start.

[elie]

read the data frome the 2 mcu in your EIS
and the esl data
with x prog and send the data to me

I repaired a IR Merc flip key a while back.
Buttons had come unsoldered and the customer had put the batteries in wrong.
You can check if it is transmitting by looking at the LED through your camera phone, if it's working it will glow purple when you press the button.
I had to re-sync it with the car by holding down the button, lock then unlock the car with the blade, then start the car. All with the button held down.

Thanks for the help guys.Fallen the w202 that I am working on is the last Version,it is NOT a flip key and it uses the same key as the w203

Go for original MB keyprog2 from www.noimmo.lt (http://www.noimmo.lt), you'll not regret it. I've used AK series from China and MB keyprog2 original from them and I can tell you when come to Mercedes IR key making don't go for China tools as totally no support at all. The ESL tools came together with the MB keyprog2 save you a lot of work when compare to china tools, their support is good. The only thing to take note is maybe you'll need to get other tools to complete your Mercedes IR key making like Xprog-M to read the dump from EIS and ECU. Somemore they support the making of ir keys for the newer series of car just by calculation of the dump from your eis.

this should work if it was just water on key

swap the mcu (not eeprom there)

[bonecrusher]

Yip.I swapped the nec's still no good.

I wanted to ask experienced users of the noimmo tool for mercedes ir key programming if there is something to be aware of , before i buy from them the tool . What i mean is if the client after i do a key for him, he orders a key from dealer too, will it work ?His exhsisting keys will stll work ? Also the ESL and ECU can be done via diagnostic socket or they also need to be removed from vehicle for eeprom reading and editing ?

If like they say it generates keys from just EIS dump then you have nothing to be afraid of as old and dealer keys should still work. I know this is possible though using Benz Commander by Abritus

[cammy25]

are you Sire abritus can calc the hashes? I cannot find anything about that on the abritus site.

[sogaro]

That info is from Miro though not tried it yet

Abritus only can repair keys.
It can read eis and esl via obd, but abritus can't read passwold EZS.

EIS (Electrical Ignition Switch)


This special function allows you to Read the EEPROM of EIS control unit and Read/Write/Erase the EEPROM of ESL control units by direct connection to the module.
Please, note that you can not read the complete EEprom of the EIS via K-line. The EEprom that the program will read will not contain the password (8 digits), the 4 bytes of syncronization with ECU (Engine Control Unit) and the cryptokey.


The corresponding addresses are:


Password addresses in EIS EEPROM: 0138 - 013F and in key EEprom 0103-010? (1st variant) or 0101-0108(from last byte to first byte) (2d variant).
Synchronization with ECU (4 bytes) - addreses in EIS EEprom 012?-012F.
The "Open ESL" and "Close ESL" buttons are only working when the ESL EEPROM is erased or in service mode.


In order to read the EEPROM of ESL CPU 1 and ESL CPU 2 the key should NOT be in the ignition lock. Just plug the diagnostic cable of the interface into the diagnostic plug of the car and open and close one of the doors of the car. After that you will have about 10 seconds to connect to the EIS and read the EEPROM of ESL CPU 1, or ESL CPU 2.


My question is can we make changes on EZS Eeprom meaning the KM like on tachosoft says address:820 and 830 and write the eeprom without password and erase ?

All the best.
