Prerequisites:
Laptop with Windows 10/11
Original DICE / Full Chip DICE Clone or Mongoose Pro/Super J2534; other adapters do not work for this
Optional: Battery charger/tender if your battery can’t maintain a stable voltage of 12,5V+ for around 10 minutes with Ignition on

-Download OpenMoose Renatus from here http://www.openmoose.net

-Unpack the archive to a folder of your choice and start the OpenMoose .exe
-Click on “Settings”(1.)
-Select your adapter type “DICE” or “Mongoose”, and the Baud rate “125/250 (-2004)” (2.)
-Connect the adapter to your car and turn the ignition to Pos. II (Ignition on/Engine not running)
-Click on CEM (4.)

-Click on “Connect” (5.) and wait until your vehicle type and model year is shown in the top right corner.
-Click on “Fast recover PIN”(6.)

-It should take 60-180 seconds to retrieve the PIN, depending on the adapter you are using
-If a PIN is found, write it down or make a screenshot

-DO NOT USE THE “Test PIN” OPTION!!!
-Click on “Disconnect” and close OpenMoose
-Ignition Off

Use this form https://d5t5.com/helpdesk/create/ticket/pin to add your PIN to the Vdash database

Or do it from within Vdash:
-Switch the Ignition to Pos.II
-Start Vdash and connect to your car
-Once all modules have been loaded, click on “Security”

-Click on “PIN, IMMO Codes”

-Click on “Add PIN” (1.) and enter the PIN without spaces
-Click on “Continue” (2.) and wait a moment

-Close all Tabs in Vdash, wait a short moment for Vdash database to update, and reconnect to your car

-Check if your PIN was successfully added in Vdash
-Go to “Security”/”Manage PINs” (again), and see if your PIN is listed

-Done

If no PIN is found, your only option is bench reading. The teensy method https://github.com/vtl/volvo-cem-cracker/tree/cem-b will also not work as it uses the same approach.
