This lock is easy to install, despite the somewhat confusing printed instructions included in the box. I lucked out that this lock fit the existing holes in my bedroom doors already. The instructions reference an "emergency unlock function" re the install but do not explain what/where/how this works. I ordered 4 of these locks and they were delivered quickly - but with the same key for all locks. I am working with myknobs to get different keys now. There was no option re this issue when ordering.
