2005 Volvo XC70 All keys lost

[Psl0cksm1th]

Hello,

Working on a 2005 Volvo XC70 with all keys lost. It has the "L" CEM and 93C86 chip. I have done several of these on the S60 and XC90 with no issues. This one is kicking my ass... I did notice in Tango & VVDI2 does not have a key maker for this model year range. I have read the 93C86 as 8 bit & 16 bit, keep getting unknow version from Tango & VVDI2. Am I missing something here? Any help or direction would be much appreciated. Thank you in advance!

You have CEM with number 00004хххххх. You still need to read m32c 30835. And use the right software. https://www.youtube.com/watch?v=hYYKml9XWlg

Orange5 clone, it did work for me, on a XC90, 30855.

It might help, you to read your 30835.

i use v1.34.
1037136
V1.40 use spi to skip sec, use data from file, boot, then switch to uart, and press read.

If boot fails,
Choose M30855FWVGP in spi menu.
boot-use data from file (00-00-00-00-00-00-00).
press boot.


Then select uart M30855FW, and press read.


No external power connector.
