2001 Volvo V70 Key Programming

**boxsport** · 10th August, 2019, 04:13 PM

I need some help from the experts here.
I'm learning about key programming, IMMO and all this stuff and i have a possible client that is asking me if i can help him out programming a Volvo V70 key.
He bought the car very cheap (because it was going to the junkyard) but there where a lot of parts missing and there is no key/s.
A locksmith made the key blade from the door barrel, but there is no chip on it.
So, i wanted to know if anyone can help me out on this key programming procedure, tools, chip type, etc...
The cars VIN number is: YV1SZ58K711004146
For now this is all the info i have.
If anyone can help me out i would really appreciate...

Thanks Guys...

You are talking about the model from 2001-2007?.
If so.
Quite a big job.
Remove CEM module. Desolder 28F400 microchip inside the CEM.
Put it in a programmer who can read these.
And then you need a keymaker who can do these.
And sometimes you can get sync error as well. (But probably not). Needs to be solved with another software.

And also solder the 28F400 microchip back, to the CEM.

Volvo dealer can do it easy and fast. If you put a standard ID48 in the key you have.

Possible other progs can read the 28F400 flash.

Thanks for the tips...
I need to remove the CEM from the car to review exactly what i will be dealing with and have more info to see if you guys can help me out...
I have these programmers:
Upa V1.3
EZP2010
k-Tag (China)
Mini Zed Bull (China)
FVDI 2018 (for volvo operations i only have Eeprom reading options on the software, but dont know what they can do)

have other tools, but for ECU reading (Kess, MPPS) and i´m pretty sure they wont work with this...

Can you guys tell me if any of these tools will work on this car?
Will it be easier to do IMMO Off on this?

thanks

Best to buy jtag, and the Volvo option.
I can recommend the dutch smok dealer.
Obdtool.nl

Some bend the brace around the AMD.
And remove it.
Using any am28f400 prog.

Hello there.
So, i just got the CEM out of the car, opened and its similar to the picture you shared.
It has a Motorola Chip MC68376 BGMFT20 Toucan TM Series.

Could you tell me if i could read and write this chip with the connections you shared with any of the tools i have?
Is there any way to read this Chip with the UPA Programmer?
If I'm able to read the chip, is it easier to just do the IMMO OFF or program new key?

Ok guys, so i was finally able to get the reading done on this CEM after a few months....
I tried to do a BDM interface (still didnt tested my prototype build, but that will be in another step/time)...
I had to buy the USB BDM NT programmer, and it was actually kind of simple to do that.
Now, i´m facing another problem that i would like to ask for some "Urgent" help....
I have a carprog (clone) unit and i was trying to prepare the transponder (s) for this, but it doesn't read the transponder. It gives me "Low transponder Signal" error. (i´ve been searching for fixes, but my carprog seems to have already the fix for the antena).
Anyway, i would like to know if anyone can help me out preparing the Bin/Hex file for this unit and send it to me so that i can write into CEM again and also so that i can prepare transponder with the FVDI tool i have or Mini ZedBull.
I will try to do one last attempt on a fix for carprog, but i need to deliver this unit to the owner ASAP, so if anyone can help me out i would really appreciate this...

Thanks
