permission denied when pushing to github because of publickey

Question

I am trying to push a repository to github. I have already succesfully pushed it to heroku. When I type git push origin master I get the following:

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I am pushing code to many other github repositories so I know it is not a general issue with my computer and I don't want to change default settings on my computer. When I type git remote -v I get the following:

heroku  https://git.heroku.com/marketvault.git (fetch)
heroku  https://git.heroku.com/marketvault.git (push)
origin  git@github.com:codeundercoverdev/marketlaunch.git (fetch)
origin  git@github.com:codeundercoverdev/marketlaunch.git (push)

How do I fix this? I've already tried this article:

GitHub Error Message - Permission denied (publickey)

but everything they mention involves changing settings on my entire computer, whereas my computer works fine for the atleast 20 other applications I currently have on GitHub.

UPDATE:

The results of running ssh -Tvvv git@github.com verify:

OK, Just ran it. I'm about to post it. None of that information is confidential, right? meaning no security risks with posting it? — Philip7899, Jan 24 '16 at 22:49
According to the log, the client sent id_rsa to the server, and the server didn't accept it. What key is it supposed to be using for github? — Kenster, Jan 25 '16 at 16:31

Make sure your private key generates the same public key as is assigned to your account on github:

ssh-keygen -yf ~/.ssh/id_rsa

should print the same thing that is available in your ~/.ssh/id_rsa.pub and the same content should be in your github account.

When I try just ```id_rsa```, I am returned a very long key. When I try ```~/.ssh/id_rsa.pub```, I get: ```@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0644 for '/Users/philipgreenwald/.ssh/id_rsa.pub' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: /Users/philipgreenwald/.ssh/id_rsa.pub``` – Philip7899 Jan 25 '16 at 18:01
I don't want to change any of my global settings because both git and this github account work for the many other repositories i have on my computer – Philip7899 Jan 25 '16 at 18:03
Read once more and just check what I asked you. – Jakuje Jan 25 '16 at 18:03
Ahh, ok. When I go on github there are no ssh keys. But if I add one, won't that affect my other github repositories? Why is it only one out of the many would be having this problem? – Philip7899 Jan 25 '16 at 18:06
It depends how do you use your other repositories. It was not in the question. But if you obviously not use `ssh`, then it will not affect them in any way. – Jakuje Jan 25 '16 at 18:08
Since I did not have any ssh keys on github, does that mean I have no been using ssh for my other repositories? – Philip7899 Jan 25 '16 at 19:25
Most probably yes. Or you were using different github account. – Jakuje Jan 25 '16 at 19:27
