Questions & Answers

Q:How can I clear all codes and set a new code?
by|Mar 27, 2024
1 Answer
Answer This Question

A:  The factory reset instructions can be viewed on the last page of the installation instructions provided below. It is recommended that you add and delete all user codes through your smart home control system. If your system does not allow this, codes may be added directly to the lock as shown here: https://kwiksetprodstorage.blob.core.windows.net/documents/kw_is_5049718_912.pdf

            Height of the indoor assembly should be shorter
            This lock has worked well and reliably for many years. The batteries generally last six months to one year depending on the seasonal temperatures and use. I have used this with both Smart things and currently a Hubitat c-7 hub. For initial set-up, both required the lock to be in close proximity of the hub for inclusion. The device works well with Siri through Homebridge and has been tested with Alexa. Alexa was not used many years ago for security concerns, but now properly configured, Alexa should work. Since this is installed below a Kiwikset Smart deadbolt it was necessary to shorten the height of the device and this does require loosening and tilting the assembly to remove the battery pack for battery replacement. The height could be easily shortened by the manufacturer since the style is cosmetic. To do this, one needs a Dremel type cutter, a scape piece of plastic, super glue and some paint.
              Don't Bother if your door has a deadbolt
              [This review was collected as part of a promotion.] After an unfortunate lock out event, I ordered this handle set to prevent such problems in the future and as a nice add on to my Ring system. However what I discovered during installation is that if you have a deadbolt, it won't work. Given the age of my home (100+) I though it may have just been the way this door was installed so I proceeded to measure the doors in my newer addition, the spacing between handle and deadbolt is the same across 4 exterior doors. Unless you have a door with a custom spacing between handle and deadbolt don't waste you money on this. The worst part is, the main body fits without issue, it is the way the cover arches up that makes it too large to fit. A cosmetic design choice renders it useless. Well why not just get a electronic deadbolt you may ask, well that won't help you when your child locks the handle and closes the door while your keys are inside, the event that lead to the purchase.

                Worked Great --- Until It Didn't
                I've had 2 of these installed in 7 years on my front door. The first died after 4 years. The second died after 3. Both died, the operation light shut off and messages came that the lock was offline. I changed the batteries --- not the first time I changed them, but this time they never came back on. In fact I put two new sets of batteries in the units. They remained dead. Not only lost Z-wave, but the outer number pad died also.
