How to fix the error

[ZodiaC]

I wanna know how to change the name of the key because it just says "picked up" but I want it to be called bedroomkey_1 or something.

you have to add in your lang file this:
<CATEGORY Name="Inventory">
<Entry Name="ItemName_KeyName">bedroomkey_1</Entry>
<Entry Name="ItemDesc_KeyName">The key to the bedroom door.</Entry>

</CATEGORY>

You may need to change the KeyName. And if you need to add more items just add the same lines above the "</CATEGORY>".

SetEntityActive("brute", false); ////This should work.

So if the entity is registered as "brute" in the Level Editor and you use the name "Brute" in the script it wont work?
