The way you link a remote repo and different ssh keys in Git is through the remote url.
Change those urls like so:

 cd /path/to/my/work/repo
 git remote set-url origin workgh:myWorkLogin/myWorkrepo.git

 cd /path/to/my/perso/repo
 git remote set-url origin persgh:myPersoLogin/myPersorepo.git

See "How to work on personal GitHub repo from office computer whose SSH key is already added to a work related GitHub account?" as a full example.
Your ~/.ssh/config will reference the right ssh key for each url:

# Personal GitHub
Host persgh
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_perso

# Work GitHub
Host workgh
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_work

Don't use "github.com" as a "Host": using an special name for the Host key is more explicit and indicates this is an ssh url you have to resolve through a ~/.ssh/config file.
