How to remove the module password in 1C?

Question

1C

In general, the accounting configuration 8.2 was inherited with documents finished 7 years ago.
It is not entirely clear why they are there, however, so far they are used.
And everything would be fine, but when creating a document, 10% VAT is automatically entered (for some reason?), i.e. sewn in the module when filling, or if not sewn, then at least see where it comes from.
But the module is password-protected, who and when made this module is unknown.
How can I unpass a module or at least see its contents?
I found processings on the Internet by decompilation - none took off. (Yes, and there are suspicions that it is she alone, renamed a hundred rows).
Error: Local\Temp\Cv8cf.dll'. 5(0x00000005): Access denied.
1C ran as administrator, and registered this library manually - it did not help.

Subscribe to the BeforeWrite event for this document and change the VAT to the required one.
The method of removing the password from a closed module is not known to me. If the executable code is obfuscated, then the decompilers available on the Internet will not help either.
