How to get all property for a custom entity in FOSUserBundle? - doctrine

Question

I am using FOSUserBundle
I created a User entity that extents baseuser, and I added a protected property I called $apiKey. The registration form works fine.
then, I created a userController that extends controller, and in a methoid to edit my user I have:
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository('AppBundle:User')->find($id);
my $user has the apiKey property but this is empty (of course the field in the DB is not).
any idea?
thanks
UPDATE: user entity
namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;

protected $groups;

protected $apiKey;
