title: Permission denied when pushing to GitHub
body: <p>I have 2 SSH key on my laptop:</p>
  
  <ul>
  <li><code>rsa_id_1</code> </li>
  <li><code>rsa_id_2</code></li>
  </ul>
  
  <p>and another SSH key on my desktop on my office:</p>
  
  <ul>
  <li><code>rsa_id_3</code></li>
  </ul>
  
  <p>My project was uploaded in GitHub using my desktop in my office. Now I want to work on it using my laptop. I added <code>rsa_id_2</code> as SSH key on GitHub so there are 2 SSH key there: <code>rsa_id_2</code> and <code>rsa_id_3</code> .</p>
  
  <p>I was able to clone the project on my laptop, but when I push my changes, I get an error stating that permission was denied.</p>
  
  <p>Was it because I have <code>rsa_id_1</code> on my laptop? And it is the one being read when I push my changes? I can't add <code>rsa_id_1</code> as SSH key on GitHub as it is being used by another account in GitHub.</p>
  
  <p>Or is there another step that I need to do to be able to push my changes using my laptop (eg. configure git, and etc.)</p>
