Well, here's some good news. Keystone shipped me a new cabinet door panel and it arrived today. I certainly appreciate them treating this as a warranty issue. All I have to do is transfer the door hardware to the new panel and I'll be set. I would recommend Keystone include some Velcro straps on their doors that are subject to being caught by a slide if the door pops open during transit. No matter how well designed and constructed, the doors will come open some time and I'd let the owner decide if they want to remove the Velcro, then any issues are on the owner.
