title: How to delete/deactivate the current PEM file and create new one in AWS?
body: <p>I have hired a freelance developer to create the AWS EC2 instance,etc settings and after that he has send me the PEM file.. Although i have the PEM file, i am bit scared if he will ever misuse it in future when we go live. So i am thinking of blocking him access to my site using SSH or filezilla or any other method.</p>
  
  <p>I was thinking of changing of keypair i.e. inside AWS EC2 console, i did the following - EC2 dashboard > Network &amp; Security > Key Pairs,  deleted the existing one (Scoot1) and created a new one (Scoot2)..
  But this option does not seems to work, since i can still access to the AWS backend files/code using the existing Scoot1.PEM files thru filezilla.</p>
  
  <p>I would highly appreciate your advice on ;</p>
  
  <p>1) if there is any other option which i can follow to secure my data of website.</p>
  
  <p>2)Also, my deleting and creation of new Key Pairs, does it impact anywhere anything, which i should take care of?</p>
  
  <p>Thanks</p>
