Thanks very much works

After XOR pin will be a7, a6, a9, a8 and the same in b1, b0, b3, b2. It's works for 16bit dumps which starts with "7F 01", "7E 01"

The same algo and pin location for 16bit dumps which starts with "6A 0C", "6B 0C" but another keys for XOR:
XOR for a6-a9 is 51 87 44 3C
XOR for b0-b3 is 5A 3C 9F 35

The same algo and pin location for 16bit dumps which starts with "04 88", "05 88" but another keys for XOR:
XOR for a6-a9 is 8D FF 3A 3C
XOR for b0-b3 is 3C 8E F7 C3

I checked this algo on different dumps with khown pin and it works correctly

Great work!!!
I can see that your provided keys works.

How did you worked out the keys?

Some dumps with known pins and known pin location, then brainstorming

Hi dont know if this will help gonna try later

Pony-prog also reads

SPI-xx160

CIM for Astra H has another algo and pin location

Hello,
When we search well we find! There is everything for it on the forum and it works very well. But you have to bother

Hi,
I share some info for Vectra CIM with 1J35D MCU (HC08AZ60)!
Dumps starts with 5E DF.
PIN location B6 B7 B8 B9 , the XOR value is: 60 35 FD 5D.

Hello,
I hope this it not wrowng place to ask this info?
I have Vectra c 2004 dusnt recognise key,Costummer buy used cim and My question it that it just 93c76 eeprom to swap from orig to donor.I attach picture with cim board.
thanks

you can swap if CIM is the same number, otherwise, read eeprom to see the pin and reset and reprogram all on car

Car it 150 km far away,
This it only solution to start this car?
Costumer bring to me both CIM

as I sad, if CIM numbers are the same there is no problem to swap!... if not you can try and report, I think 90% will work...

**Shmortz** · 26th February, 2020, 11:54 AM

... but if the problem is nto im CIM himself, will not work if swap eeprom on same number CIM, are yu shure key is ok?
try to read CIM on bench and see if it work good and can read key or not after swap eeprom

**dragoshu** · 26th February, 2020, 12:39 PM

Solved,
I found ring damaged,replaced and ready .
thanks
