Repository access denied. access via a deployment key is read-only

After successfully cloning my repo from heroku and added another remote

1/ git clone git@heroku.com:[APP].git
2/ git remote add bitbucket ssh://git@bitbucket.org/[ACCOUNT]/[REPO].git
3/ git push bitbucket master

I am still getting this error after running line (3) or using SourceTree

conq: repository access denied. access via a deployment key is read-only.

First I don't understand what this message means in practice. And that's shame.

I did create ssh key pair and added to heroku :

ssh-keygen -t rsa 
heroku keys:add ./id_rsa.pub 

I also added my key in deployment keys section in BitBucket. But I must be missing something. This question is not out of laziness, I have been reading various docs including BitBuckets guides. But it still don't get around this issue.

This post is related to Can I import my heroku git repo into bitbuket? and how?

ADDITIONAL FACTS:

ssh -T hg@bitbucket.org
conq: authenticated via a deploy key.

You can use git or hg to connect to Bitbucket. Shell access is disabled.

Looks like all is fine.

First confusion on my side was about where exactly to set SSH Keys in BitBucket.

I am new to BitBucket and I was setting a Deployment Key which gives read-access only.

So make sure you are setting your rsa pub key in your BitBucket Account Settings.

Click your BitBucket avatar and select Bitbucket Settings(Manage account). There you'll be able to set SSH Keys.

I simply deleted the Deployment Key, I don't need any for now. And it worked
