Review: A GREAT DOOR LOCK!!! - I'm thoroughly satisfied with the Latch 5 that I purchased. I upgraded my door locks with the Latch 5 Fingerprint and paired it with the Lock Deadbolt. The ability to program from the app how I want them to work is a gamechanger. I can have either of them open once either 1 is unlocked. The setup and installation is super easy, the instructions provided are detailed and you really can't get lost or mess it up if you follow step by step. The real shining star though is the support from the company that you receive. They are on top of any issues you may have and are dedicated to making sure that you are satisfied with their product and respond promptly to any questions or issues. I would definitely suggest investing in their products. The only drawback is, they don't have enough products yet, lol. I'm really interested in the upcoming camera system they are working on. Also, their products work seamlessly with Samsung Smart Things (low-key the reason I tried them), so itz good to be able to utilize the Smart Things app and be able to control the locks and get notifications. Also, the notifications of who and when the locks unlock is nice. You can also setup a bypass mode where the locks remain unlocked and you can use the door as if it didn't have any locks on it period. Inverse you can also lock it so all remain locked no matter if a code is input or not. You can also give out temporary codes for people to use. They have really taken the time and invested quality improvements into bringing a great product to market! I can't say enough about the company and the products that I have, TRULY SATISFIED!!!
Review: Good, responsive customer service. - Had this unit for about 2 years before the keypad started malfunctioning. Reached out to customer service and they sent me a new exterior assembly even though I was technically out of warranty. Much appreciated! The unit now works again as it did when I purchased it.

### ⭐⭐⭐⭐ So far, so good!
*by T***E on October 8, 2023*

My Yale/Nest lock became increasingly flakey, going offline sporadically until, after resetting it many times, it eventually refused to connect at all. (I worked the problem for a *long* time before giving up and buying this as a replacement. There were a lot of people online with the same problem and the "fixes" didn't help.) I was pleasantly surprised that the installation was easy. The only part of the installation that was poorly documented was the bit about the door sensor. The door sensor monitors whether the door is physically shut or not (since the deadbolt can be operated regardless of whether the door is open or closed). I watched the YouTube video and it explained things better that the written instructions, so, overall, installation was problem-free. The app is a little over-engineered, in my opinion. You set up "Addresses", "Locations" within an Address, and "Devices" within a location. I suppose it makes sense if, for example, you owned several properties with multiple buildings on each, with every unit in every building having two or more devices. For a person like me, with just one lock at a vacation home, it's overkill and unnecessarily complicated. The features of the app are great, comparable to what I had with the Yale/Nest lock. The two major differences are 1) that the ULTRALOQ has a sensor for when the door is open or shut and 2) the way to handle dead batteries. The Yale/Nest lock has contacts on the outside where you hold up a 9-volt battery to the lock, powering it long enough to get it unlocked. The ULTRALOQ has physical keys. I like having the physical keys very much, but they are no use if the physical key is not present. For example, if I wanted to give access to guests and the batteries were dead, I would have to drive hours to meet with them and get the door unlocked. It would be ideal to have both features: battery terminals AND physical keys. But I can't really knock it for not having a feature that I already knew it lacked. That said, the ULTRALOQ app tells me how strong the batteries are, which the Yale/Nest lock does not do. Another cool feature of the ULTRALOQ is that I can take it off the WiFi (and lose remote control capability) to extend battery life. I don't want to do that, but it's cool that it's possible. Replacing the batteries is easier with the ULTRALOQ. You need a tool or thin toothpick to get the battery cover off the Yale/Nest lock. The ULTRALOQ cover comes off just by applying gentle pressure. The ULTRALOQ has an "autolock" feature which seems a little too aggressive. I turned this off because I sometimes want to leave the front door open without the lock taking it upon itself to lock within seconds. There is also a feature to automatically unlock whenever a configured Bluetooth device approaches. That's also too automatic for me, but some users might appreciate it. Updating the firmware on the ULTRALOQ was a big pain. It took several attempts which failed randomly, despite the WiFi being strong and my phone being right next to the lock. That did not bode well, as it reminded me of trouble I've had with other devices. But it eventually worked. I would change my rating from four to five stars if the firmware updates worked more reliably and if the app was organized more intuitively. But, so far, the lock is working well and it has almost all the features I want.
