Unprotect/Reprotect Sheet During Email Vba Code

I have an email vba code set up in my workbook that emails the worksheet in an attachment to someone. However, I keep getting an error code saying permission denied when the code tries to finish. It highlights the "Kill Tempfile" field...which in my mind is saying permission denied because I have the worksheet password protected. I kind of want to keep it that way, so is there a way I can enter a line of code in my current script to unprotect what is being emailed in the beginning of the code so that the tempfile created when it is being emailed can be deleted?

Here is my current
