    Can't say I've ever seen this model before, but from looking at the zoom-in of pic3 it appears that there was a lot of debris in the keyway before you cleaned it out. Do the pins move freely now or are they a little sluggish? Could be some dirt or corrosion in the pin chambers, running the key in and out repeatedly with tri-flo or lock saver might free them up and get the key working. My best guess without having it in hand, good luck.
    BBE,

    thank you,sir
    pins are moving up and down,cylinder moves a little ,pins dont seem to stay in when picking,with light or hard pressure
    only feel 4 pins i will keep tri floing and picking
    the soldering and angle of keyway was not seeming correct
    thank you,Mr Edwards
    appreciate your help

    You might try a bump key as a last resort. The pull type would work better than a push type as there would be more travel of the key and the force might help loosen any obstinate debris still in there. Just in case you might not be familiar with the pull type, the key should have one more cut on the tip slope of the key and pull it out one cut before impacting.
