Review on 🔒 Master Lock BCO0115 Keyed Entry Door Lock with Biscuit Style Knob in Satin Nickel Finish by Matthew Carr

I just threw away the entire manual because it was too confusing. All I did was take the old doorknob off, watch it put together and just do it for the new one. I didn't need the other 3 parts at all, just the one for the doorknob because they fit perfectly into the existing "latch" hole (I think that's what you would call it). It closes and opens perfectly and is very secure. I thought it would be difficult, but it turned out to be so easy. I just used a screwdriver. The only thing is that I had to use my hands to get the screws halfway in because the handle on the doorknob got in the way when screwing in the screws.
