I'm speaking from my personal experience with Kwikset lock. Like I said, it's cheap version, not z-wave one. It is not tapered. Here's how it works with manual - you try to turn it, it doesn't turn. You pull the door tighter, until it turns. Done. Here's how it worked with this Kwikset - you press the button, lock makes noise, fails to engage, the door stays unlocked. Maybe not an issue for me - I can check. But my parents could forget. Cleaning lady is not likely to check, etc. this is a real issue, not some argument I've read. Not bashing Kwikset at all, BTW. Just prefer manual myself.JonW said:
I've seen the same argument many times, but if your door is tight and a motorized deadbolt has an issue, then so does your manual lock. Do you just tell people to turn the lock harder because it's tight? Just fix the problem with the door and then it's not an issue! Also, the Kwikset locks have a tapered deadbolt and a lot of torque, so your door or lock has to be misaligned pretty bad for it to not function..
