August HomeSmart Keypad, Pair with Your August Smart Lock - Grant Guest Access with Unique Keycodes, Dark Gray

first unit I got from Amazon warehouse deals was non functional, perhaps it was the reason someone had returned it, no backlight or bluetooth signals detected from it even after changing the batteries. I did however notice what seemed to be after damage on the circuit board inside the unit. So just be aware that if you buy one from Amazon warehouse to make sure it works, and that it's not tied to someone else's account still, at you won't be able to add it to yours until they disconnect it from theirs and type in the unique reset code that August app sends you when this is done. (I know only from research as I thought this was the issue, but it wasn't until I got it exchange through Amazon warehouse that I realized it was just that the unit was not functional as soon as the replacement lit up in its brilliant red backlight when I put the batteries in.)ever since I got the exchanged unit from Amazon I've had no real issues. The unit reports low bluetooth signal but has never had an issue connecting quickly and reliably, I imagine it's very difficult to connect via bluetooth Low Energy spec and being in the difficulty position of attempting to communicate with a lock that is behind a (in my case metal, metal reflects RF energy) door, plus a wooden frame (wood absorbs RF energy, as does any organic compound) and a cinder block or brick wall plus insulation material (reflections from radiant barrier insulation and stone based building materials including drywall, and lead based outdoor paints which all reflect RF, and interior and interior wall paints which absorb rf as they are typically organic based (oil is organic and absorbs rf energy) with a double whammy because paint is also designed to be fire retardant making them semi reflective rf wise, then and in a humid Florida environment (water absorbs RF energy the best/most and people are mostly water so your hands near the keypad after entering the code will hamper connectivity too. not to mention that's how microwave ovens work which just the exact same frequency band range of 2.4GHz, and WiFi is also 2.4-2.49GHz so there's that constant noise coming from every device and WiFi router and bluetooth device) I imagine this is why the keypad is made of such a lightweight plastic as anything sturdier would require an external antenna, or a more powerful radio which would make it not possible to be battery powered. As it is, bluetooth le devices are typically powered by coin batteries, think Tile. Which get a year or life via bluetooth le or more. So 2 AA is definitely in there because they had the space to do so, to overcome the above difficulties stated above, and for longevity.SUGGESTION: I believe that if it were possible to refresh the design in such a way where the antenna(s) were printed on the edge of the device or somehow located behind the batteries this may improve communication as the batteries themselves may be reflecting some of the signal away from the lock perhaps. Or making the keypad slightly larger so it could be used with gloves on more easily, further separating the distance between the users fingers (which absorb bluetooth) may allow for better use ability and transmission. Also the size would make typing in codes take a fraction of a second longer, thereby fixing the issues I've read others having with entering the codes in quicker than the keypads power effecient cpu can process them.

I’ve had this awhile and simply love it. I love the fact that I can set it up to unlock the door when I arrive home and to lock it after it has been unlocked for a period of time. When I have company around and they are in and out, I turn that feature off. Easy peezey

The media could not be loaded. Awesome. Just works. Bluetooth always stays connected. I have the August circle-shaped wifi smart lock in my rented apartment with no bridge. So renter friendly because it replaces the back not the front so the landlord still uses a regular key to get inside. I have my lock set up to automatically unlock when I get close with my phone but it doesn't always work or I don't always have my phone. You can set up codes for individual people in the app 4-6 digits and control times of access. Pushing the august button locks the door. There is a backlight that is motion activated but I have it turned off in the app because there is a lighted hallway where it is put. You do have to be in bluetooth range to edit the settings of the keypad or add/edit codes. However say you're away from home and want to remove access for someone, you can delete them all together with your lock connected to wifi and their code will not work anymore. I have someone come clean for me and it is so nice to have her be able to get in. Or I can also give temporary codes to people like the Walmart+ driver or someone who is staying the week with me.This device is reliable, lets me give access to my apartment to whoever easily, and gives me peace of mind to not be locked out of my apartment.

ORIGINAL REVIEW: Works like a charm with the lock! Had it for a week so far. Love how different codes can be set up to different phone numbers. No more leaving keys near the door! Noticed some bonus feature is that it actually buzz for a while if you get the code wrong multiple times, as if to catch attention that someone tries to get in but failed.UPDATE (7/05/2019): Putting this back to 4 stars. Ever since August replaced the Keypad unit the whole combo of lock and keypad has been working well with several months of battery life. As you can see I have had the locks and keypad for several years now. I still have battery saving mode on and homekit disabled just in case history repeats itself. Otherwise no complaints.---- HISTORY ----UPDATE (8/20/2016): Dialing the stars from 5 to 2. I have installed the keypad for just about 30 days; Problems started around 10 days ago when it won't unlock at all, but recovered by itself several hours later; Luckily we had our phone to connect to the lock directly. Then yesterday while everyone was out our dog sitter took the dog out using her code, but couldn't get back in after standing there for 15 minutes trying !!!!!! When I got back, at first the keypad had no response and no light, figured the battery must have died, but without further tempering the keypad works again later in the evening.... We use the keypad just about 2-3 times a day, each time once to lock it behind us, once to open again. I see from other reviews that this range of battery life seems to be consistent. But if it starts being temperamental at 20 days, this really means you have to make sure you keep the battery fresh within that time... which is... i must say, disappointing. I see August is recommending turning off the proximity backlit feature, I will try that and see when the next problem comes... hopefully you won't hear from me for months.UPDATE (9/20/2016): The Keypad continued to be temperamental. The firmware update recently helped not much. Tried replacing both the locks and the keypad batteries at the same time using Duralock batteries. I now use keys to get back into my house. Possibly seeking a refund here. I liked the idea very much but this is turning out to be a slap in the face for spending money.UPDATE (12/27/2017): In June/July 2017 I finally contacted support@august within the warrantee period, at first they asked me to test a few things, and eventually they gave me a brand new replacement keypad with drama. With the new unit, I have removed the lock from HomeKit; and when the August App/bluetooth is not competing to connect to the Lock, the Keypad works quite reliably. The battery life seem to have improved too, it definitely seems to last more than a month now. I am actively using the keypad, six months on after replacement, no major problems, albeit without all the bells and whistles, at least it is usable, still carry and ask guests to use keys though.
