Does anyone know whether the smart lock cylinders are interchangeable with other Kwikset components? Better yet, can I just install the interior component of the smart lock on top of the existing cylinder / bolt? Is there something different about the guts of the smart lock? Our front exterior handleset is one of the styled ones and I can only get away with installing a smart lock if I can keep it all matching.
The guts, as far as the cylinder and latch, are the same. I won’t go as far to guarantee to you it will fit, but I would be willing to try it myself.
I also cannot guarantee your setup, but installed a 910 with an already existing qwikset deadbolt on the outside. I had zero issues.
Thanks! It seemed obvious that they should be compatible but you never know. I just ordered a keypad for the back door - I’ll check the interior side on the front door and confirm fit before I order another unit.

I actually am planning to do the same for my garage doors and patio doors as these often get left unlocked…but I do not want the keypads on the outside. Let us know how it goes.
Kwikset offers a lockset without a keypad that sounds like it would do what you need (here’s the basic one).
My issue is the trim - my front door has a Chelsea handleset, so it would look wrong if I replaced the exterior deadbolt trim with the “traditional” or “contemporary” trims shown in the installation instructions. If I can just slap the motorized component on the back of the existing deadbolt though, I’m in good shape.

Great to know, I did not realize there had a keypadless z-wave solution.
Regarding yours, from memory, I recalled there was nothing special about the exterior lock itself. There is a 4-wire you have to pass through to the door for the keypad. But you go with the 910 that is keypadless, I see know reason you cannot just provide your own exterior assembly.
Have you compared the installation manuals to ensure the internal parts are all the same?

Looks the same to me, and it seems like there’s no reason they wouldn’t be. I’ll find out this weekend and report back.
I put a 910 on an existing dumb deadbolt (rear door where no keypad required). The outside part with the key on the new 910 set did not exactly match in design/looks to what I already had so I installed just the inside part from the new 910. I left the existing latch and outside key part in place. All is good.
This is what I used …

Update after installation this week:
-
The cylinder is larger than my original (~2010 vintage) - I couldn’t just swap the existing cylinder into the new keycode trim, instead had to use the SmartKey rekey to keep the new lock matching my front door.

The spindle and mounting screws seem to be the same; I was able to put the motorized interior portion of the lock onto the old cylinder. I did not try fully assembling it but it looked like it would go together fine.
So all looks good, as @Nezmo confirmed, and next time my wife says “I’m pretty sure I locked the front door” as we go down the street, I’ll be ordering another unit for that door.

PS only complaint - this sucker is LOUD. But I guess it’s handy to sit in my living room and know when someone’s unlocked the door downstairs…
It is loud, and somewhat annoying. But on the other hand, I can be anywhere in my house and hear if someone is opening the door. My front door is done but I still need to do my garage doors and patio doors.
