Your activate() and deactivate() methods should call the parent's methods:

activate: function() {
    if (!OpenLayers.Control.prototype.activate.call(this)) {
        return;
    }
     // your specific code goes here
}

deactivate: function() {
    if (!OpenLayers.Control.prototype.deactivate.call(this)) {
        return;
    }
     // your specific code goes here
}

In this way, you need not yourself set active to false|true.

Do you pass the appropriate parameters to unregister()?

Sorry for misreading your former post! What you probably can do is
unactivate() the Navigation control.
