Dear Sir, i have same problem as posted with old type IR key. I have the equipment for key repair but i only got it 3 days ago and i dont know exactly how to use it although there are videos as manual. Could you possibly explain to me the proceedure and any tricks ?
The key is NO CONNECT in repair software, but i pit another motorolla in that circuit board and it works so the problem is inside motorolla not on circuit board. Also should i use motorolla that came with key or put a new one in ? I manage to read eeprom from damaged motorolla so i cannot know why it doesnt work.
Hope hearing from you soon

What is important are your dumps from eis and esl, post them here and you can get a working key data sent to you which you can write to key, if the ori chip does not work well then use another if you have it, but must be same mask.

Is there any info about bench setup of ESL, EZS and keys on W210? I'd like to test my work before go to car.

Thanks in advance.

I'm trying to write a dump from W210 EZS(210 545 00 08, 0D69J inside) to another EZS(210 545 03 08, 1D69J inside) and it is not working. Is that normal?

Is there any 210 545 03 08 dump to test?

Regards

In the ZIP file, i have 2 pair of files.

The files named "after testing" are the dumps that I read after test the EZS on bench with key and it is not working.

For some reason they are change by themselves.

Any suggestion?

Hi , i had a w210 that the key wouldnt unlock EIS and ESL, i tried to read EIS by diagnostic connector, but i was getting error messages while trying to read, eventually i succeded but then the file had some error in size so i removed both cpu's from EIS, load dumps in software for key restore and the 4 hashes where found.
Now i can start the car, but the remote doesnt work on the car like before. The central locking is dead, just the hazard lights flash when pressin unlock button.
Is that key problem ? Even the button on the dashboard is not working.
