How do I push commits to a local repository with an SSH key?

[jmkd3v]

I have a local repository that I've already cloned and I want to push changes to remote (GitHub) from a different account.
I've tried something like this:

id_file = os.path.expanduser('~/.ssh/id_rsa_api')
id_cmd = "ssh -i " + id_file
repo = Repo(path)
with repo.git.custom_environment(GIT_SSH_COMMAND=id_cmd):
    # rest of code here

but it's had no effect - the commits always are pushed under my main GiitHub account, no matter what SSH key I use.

Did the GIT_SSH_COMMAND environment variable have an effect when running git on the command-line directly?

From the code I see here I would expect this to be picked up when interacting with remotes.

Odd - it does not apply in the command line either. Maybe I should remove my main account from Git and try again?

Update: I was able to solve this problem by deleting my GitHub credentials and then changing my email and username on the local level.
