Error on deploying with Git on Heroku

I’m not able to deploy in Heroku. I’m getting Permission Denied! everytime. I have my repository already exists.

$ git remote -v
heroku  git@heroku.com:catapp11.git (fetch)
heroku  git@heroku.com:catapp11.git (push)

But while I try to push in Heroku, I always get error.
