> 赤鍵は抜刀 **に** 許可が必要です。

This one throws me off a little bit. Does it bear the same meaning as "には" (in
order to) or is it different? Or could it be another way of using the verb 許可?

The only way I could translate it would be : I need permission (in order) to
draw the red key, but I usually always encounter には so に alone disturbs me a
bit.

question
grammar meaning
に in this sentence
> 「赤鍵 **は** 抜刀{ばっとう} **に** 許可{きょか}が必要{ひつよう}です。」

is a grammatically perfect sentence meaning:

> "Permission is required for the unsheathing of 赤鍵."

(I presume 赤鍵 is read あかかげ, but since I could not be certain, I left it in
kanji. The word must be a proper noun.)

「には」 cannot be used in place of 「に」 because **「は」 as a topic marker** is
already used in 「赤鍵は」. You cannot use it twice.

As you stated, 「～～には～～が必要」 is a common phrase and it can be used in the
sentence in question **_only if_** the necessary alterations are made. That
sentence will be:

> 「赤鍵 **の** 抜刀 **には** 許可が必要です。」

The 「は」 in the original has been changed to 「の」 so that the topic marker 「は」
is used only once.

To use the 「～～には～～が必要」 construct correctly, you must place either a noun or a
verb in the dictionary form right in front of the 「には」. 「赤鍵の抜刀」 is a noun
phrase, so it works out fine.

What happens if you used two 「は's」 in this sentence?

> 「赤鍵 **は** （、）抜刀 **には** 許可が必要です。」

This sentence is still actually correct and grammatical, but the meaning will
change somewhat because now the **「は」 in 「には」 will be the constrastive
marker**. Thus, this new sentence means:

> "Permission is required for the unsheathing of 赤鍵, ( ** _but it is not
> required for doing something else with 赤鍵_**.)"
