    It is exactly what I was looking for. I wanted a non electric lock that worked and easy to operate.No more lost keys.
    MARVIN -- apo, AE   10/23/2011
    This deadbolt works great! I run an aidstation and have many sensitive items that need to be locked away and when I saw this It worked perfectly. Everyone that saw this wants to order one when we redeploy back to the states. Thank you again!
    Terri -- kamiah, ID   5/14/2011
    Easy to install and easy to use. I bought 2 and love them. This is the best product I have found that can't be picked. Thank you!!
    Terri & Larry -- Idaho   5/9/2011
    We had people breaking into our house and my studio, some how they we're picking our keyed locks. We bought 2 of these keyless digital deadbolts and no more break-in's. THANK YOU SO MUCH
    BRYAN -- big bend, WI   5/10/2010
    Very easy to use install and operate. Design concept with no wires is a home run. Lock runs very smooth
    ROSELOUISE -- maplewood, NJ   5/10/2010
    The item shipped fast and came exactly as described. Thank you
    JOE -- bakersfield, CA   3/15/2010
    Works just as you would expect. Setting the code is a bit confusing. I am happy with the purchase.
    GUNTER -- henderson, NV   2/18/2010

    GREGORY -- saint clair shores, MI   2/11/2010
    Easy to install and provides rock solid performance. I'll probably buy several more! Highly Recommended!!!
    EDWIN -- saint louis, MO   10/15/2009
    Easy to install and easy to change combination. Brass inards so looks like it should last for a long time. I replaced an existing deadbolt with it. The existing hole was just barely covered by the rubber seal on the keyless entry deadbolt. I had an old computer case laying around. I traced the black rubber backing seal that comes with the keyless deadbolt onto the sheetmetal computer case and cut it out so that the outer size was a little smaller than the rubber seal so it would not be seen and used that to strengthen and cover the oversize hole in my door. Can not see the fix. Made one metal plate for each side of the door. Only needed if you have large existing hole.
    THOMAS -- soldotna, AK   9/5/2009
    They install easy on both setback lengths, work great, AND no batteries. Seem to be well built, and will buy more.I had the kind with batteries, but I won't anymore.
    AARON & SHANA -- south euclid, OH   7/28/2009
    Works like a charm. We never have to carry keys anymore!
    JENNIFER L. -- dallas, TX   7/12/2009
    This keyless entry deadbolt solved all our problems. It was very easy to install and I like that it is not electronic and does not require batteries. Thanks
    ROBERT -- santa monica, CA   5/6/2009
    instructions and install a bit more complex than anticipated, however it is worth it when its done. Now we don't have to take the house key when we go for a run.
    DAVID -- portland, OR   8/22/2008
    It was VERY easy to install and is far easier to use than the electronic versions. Most importantly you can easly lock it from the outside without a key. I would highly recommend it.
    John -- Southern California   4/9/2008
    PERFECT! Works just like the deadbolt that I removed to install this one. It doesn't lock by itself, you have to turn the knob which allows you to use the door all day without re-entering the code. The installation and code change instructions were great and it comes with every possible part. Regarding the customer comment about it freezing / not functioning in Alaska''s freezing climate....MOVE!!! (and take your 51991SN door lock with you ;-)
    RICHARD -- punta gorda, FL   2/28/2008
    High quality product - relatively easy to install. Fast shipping.
    PETER -- vancouver, WA   2/21/2008
    thank you, great service and product.
    A.P. -- nashville, TN   1/23/2008
    I have had one of these on the door to my house and it has worked perfectly for six years now under heavy use.
    DAVID -- skokie, IL   7/30/2007
    I was so impressed with this product, that I ordered another one for a different door, soon after installing the first one. Best features: no batteries needed, very sturdy construction, Worst feature: a slight hassle to change the code, if you would ever want to.
