Excellant Safety feature locking from both sides

By jonnie m

from Aliso Viejo, CA, United States

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

After I purchased and installed the dual cylinder lock (key used on both sides of cylinder to prevent someone from reaching in and turning deadbolt by hand after breaking window) I knew what was coming from my wife---we can't have this, if there is a fire getting key and unlocking will not work. I showed here the slot in the wall I made with key placement and also were i put a secondary key (also near the door). Once again i was told this will not work. I showed her the benefit that if someone broke a window they could not reach in and unlock door and left it at that. Over the next few days I watched her as she would run, grab stored key, and unlock door. I also observed her doing the same---but without grabbing key and pretend to turn a deadbolt handle. I never brought up the issue again and after a few days when she left to run errands I took out the Double Cylinder Deadbolt and i reinstalled a traditional Single Cylinder. When she returned the very first thing she said was why do we have this unsafe lock back in the front door. I believe that the above story tells it all. When you want safety, you want Kwikset and the Double Cylinder Deadnoult


SmartKey makes security easy

By rmjb

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

In my parents house the key bundle can drop your pants. When I built my house I used all SmartKey deadbolts and handle sets. Each door has a deadbolt and some doors have a matching handleset. I standardized on the 985 Double Cylinder for the deadbolt. Now the key bundle on my house is only 3 keys, by choice. And still, very secure.


Single key for all the doors! And re-keyable!

By arun

from India

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

I love these locks.... a single key for all the outside doors - front, back and side - makes it so convenient. On top of that I have bought a smartkey kwikset padlock for the gate which also opens with the same key. Convenient and minimalist. No problems for past 2 years. One lock was a bit sticky and was not opening well with the key... I rekeyed it to the same key and now it works smoothly. The satin nickel finish has stayed well.

Outstanding Product

By Ravenkeeper

from California City, CA, United States

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

A few years ago, we purchased this deadbolt setup to replace the set on our front door. The one we had, had a handle on the inside to lock/unlock. Some friends of ours, who had a similar door, had their side windows broken, the criminals reached in, unlocked the door and made off with a lot of their stuff. The next day, we bought this set. We have a spare key, hidden, in the house for evacuation purposes, but we know that they can break the side window and NOT get in.


Installation Instructions are lacking

By frank56

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

I think that after all these years of making locks you'd have this down to a science that's real. 1). Enlarge the instructions. 2). Create a better way to align the latch with the strike plate, 3). Provide problem resolutions on the instructions.


Good Deadbolt & SmartKey Makes it even better

By Highmaster2

from East Central Alabama

Comments about Kwikset Signature Series Double Cylinder Deadbolt with SmartKey in Satin Nickel:

Have been using 4 of these for 4 years now. Installation instructions were clear and easy. They have held up well. The outside portion still looks like new. Really like being able to re-key easily whenever I need to do so. Will never buy another keyed lockset that isn't a SmartKey.


Not so happy camper...!

The set of two keys inside the package didn't work with one of the cylinders. Have to say it was prett easy to install. I Just uninstalled to bring it back to the store
