VVDI, AVDI, AUTOHEX, BMW EXPLORER, YANHUA....... a quick search of the world wide web will yield tons of information.

The best will be yanhua....no need remove components and cut the trace in CAS4

What fried original CAS? Replacement CAS has its key?

Open new cas and read chip type and share,

We try correction now chip is gone and replacement CAS has no key but can try to get original key. Also have key programmer with super Dp5 chinese tool.

There are a few affordable options
1- get the same part number CAS, and clone the data from your original to the new module.
2- get a cas dump with known ISN, change VIN, ISN, and mileage in dump, write to module and make some keys.
3- get a CAS with key, and change VIN, mileage, and ISN.

My favorite tool for this is Hextag

Check if both cas units have same chip then just clone old cas!!
