I bought a house that had this Kwikset Powerbolt on it. It worked fine for a couple years and recently became stuck in the unlock position. It feels like a magnet or spring is resisting it from opening, but I can’t confirm, so figured to sell it for parts. Was a great and very durable lock until then. I think it’s the Powerbolt 2 model, but old owners didn’t leave me a manual so unfortunately I can’t confirm that theory. Anyways, I figured someone could use it or repair it have and have a good lock for cheap. No key included.
