Another weird one. Got a R230 one today with keys 2 and 4 used and all others unused, showing 4 and 1 as last keys used. Now yours shows keys 1 and 3 being the only ones used with last keys being 3 and 0. What's the info of the key you currently have? Do you have a ESL emulator or an unlocked ESL? What's the part number of your EIS?

Hi. Yes I do have the esl emulator, why?

Narrow down potential sources of the problem, use it on the bench to test the key and EIS. :)

[dd1]

Yes I have the esl emulator for it

Then try it. What's the SSID, number and status of the key?

Ok I am new to this. The ssid Eis and key are a bit different, key is 8B9DAB9C and Eis 889DAB9C. And the key I read is number 4.

Yup, x8 is key0, so xB is key3. It shows it's status as being used or new? Did you make this key?

[dd1]

No I have not. It seems like it is not a new key.

program key on other unused position and will work, I do this at least once a month...

Thanks, so for this kind of problems always goes the key? but why is the ssid number different? Is this the problem? If so any other way to fix this issue?

Thought I explained the key numbering above. The SSID isn't different.

8B9DAB9C and Eis 889DAB9C. it is different. look, one starts 8B9 and the eis starts with 889

Maybe a better explanation :):
88 9DAB9C : key0
89 9DAB9C : key1
8A 9DAB9C : key2
8B 9DAB9C : key3
8C 9DAB9C : key4
8D 9DAB9C : key5
8E 9DAB9C : key6
8F 9DAB9C : key7

The SSID in the EIS bin can be considered as a base or key0 ID.

Nice. Now how I do get this Eis fixed? Thnx

[dd1]

I just added another, new key to a different slot and still the key wont turn. I use emulator for esl

Time to look for a clone donor. Software for the current one looks ok, so the problem is either mechanical or electronics failure.

again i say, a ezs dont only excist out of flash and eprom!
