Illustrator Scripting :: Unlocking Locked Text On Unlocked Layer

When running my script to unlock all layers, so I can select all textFrames and copy them to a new layer, I run into a problem with text that has been locked individually. The script unlocks layers that are lock but it does not unlock items that have been locked individually on those layers. Is there a way to unlock these items?
 
var layerCount = activeDocument.layers;
for (  j = layerCount.length - 1; j >= 0; j-- )
    {
    lockedLayers = activeDocument.layers[j];
     
        if (lockedLayers.locked == true && lockedLayers.visible == true)
        {
        lockedLayers.locked = false;
        }
    }
