We're here at the brand new LT tech house where I'm going to be uninstalling
this old lock because Aara sponsored this video for us to check out their new
smart lock U400 which I will be installing. This thing is so cool
because I hate having anything extra in my life at all or on my person. I don't
want to have house keys. I don't want to have a car key. I don't want to have a
wallet. If I can just use only my phone for everything, that would be great. Or
even less than your phone. That's what this puppy allows you to do. You don't
even have to use your fingerprint or keypad, though you can. You can just
walk up to it and it will unlock. All right. In the box, easy setup with the
Accara Home app. There's a QR code there. Some instructions,
presumably some hardware, a little template for setting it up on your door,
especially if you have to drill new holes or chisel stuff out. There's a
little bit of hardware in here and a little adapter plate guy. This side up.
This looks like a rechargeable battery via USBC.
And the lock itself,
this is a matte black, very minimal
design. There's the deadbolt you turn over. You've got the inside part where
the battery goes and this little squishy
silicone ring for sealing and the front
outside part where a little door reveals an actual physical keyhole for your
grandparents. what I think is like a biometric little
pump. And according to the box, it'll be this area that illuminates with a keypad
that you can capacitively interact with. Installing a deadbolt is super easy. I
assure you, you can do this yourself. Now, all you need to do in general is
you're going to have a piece like this that comes with this lock that goes in
there. This rod fits through the little slot in there and then connects over
here. And then the wire is going to feed through that hole and plug in over here.
That's the basics. Now, however, we run into a little snag over here. The piece
that comes with the Accara U400, see it has this little rectangular guy that is
meant to nest in a carved out little
slot on your door. Now, this door does not have that. I'm not prepared to take
out an oscillating saw and a chisel to carve such a recess in this door of the
tech house cuz I'm not sure we're allowed to, to be honest. So, don't do
what we're doing. We're sitting proud like this. We're just trying to get this shoot done. And you know what? It works.
One other note, while we're in the latch zone here, if you put it in and it looks
like it's not going to be centered in there, you might have to adjust the back
set, which you do by just turning it. See how it gets longer?
Now, it's time for the hardware. Now, you can see from the previous lock that
was on here, it required drilling into this door. This lock doesn't need that
because of this puppy that we saw earlier. I figured out what it's for. It
goes on here like so.
And you can see now that there are spots for bolts here which will go into the
other piece that's on the other side and sandwich it. Once you put this side on,
you got these little screws that are included that go into these holes
through here and into these motherboard standoff like kind of receptacles and
not into your door. Rent friendly.
Next, we have to put in the battery. And this is really interesting how this works. You can pop this out of here and
go charge it somewhere else. Or you can charge this while it's in here without
even taking off this plate by using the USB port that's down here. Or if you get
locked out of your house, the batter is dead. You don't have your keys, nothing.
You can still actually charge it from the outside by using the USB port down
here. Just a note, these cavities are pretty narrow. They're actually too
narrow for our LT screwdriver to go in
there. So, either get one of our precision kits or something like a fix
shaft. Oh my god, not magnetic. I really
wish they had included like a really inexpensive screwdriver or Allen key to
do this. A lot of products do. Now that we're installed, the next step is to
pair this to the app with a QR code.
Now, I have to bind the door lock by bringing my phone close to it and
pressing this button. Added successfully. Time to name it.
I've added a keypad password and now I'm going to add a fingerprint. So, I have
15 seconds to put my fingy on here. Ooh.
>> Close the door inside without locking it. Then press start. Calibration.
Calibration successful. I've got the lock in my Apple Home app. I can hit
lock. It locked. Now, let's see the magic happen with UWB.
All I do is walk UP TO IT.
OH, it said UWB.
That's awesome. It totally works. You don't even really have to slow down.
When you're just out of arms length, it unlocks. You can just like walk right
in. You don't even have to stop walking. Pretty sweet. But a lock could do that
with Bluetooth. It just has to know you're near. The difference with UWB is
it knows your directionality. So, right now, this lock is not unlocking even
though I'm near it because it knows I'm on the inside of the house. It's also
more accurate. Bluetooth only has down to 1 meter accuracy, but UWV
centimeter accuracy. But let's say your phone doesn't have UWV, but you have
NFC. You can still unlock just by tapping your phone. It obviously has
auto locking, which is really nice, but not exactly special. What is special is
that UWB is more secure than Bluetooth because someone can actually intercept
and amplify your Bluetooth signal, making this thing unlock when you're way
out of sight. UWB uses time of flight to calculate the distance. And it also uses
cool things like scramble timestamp sequence to like add encryption and just
make this whole scenario a non-issue. It already was pretty niche. Related to
autolock is that stupid nightly routine where you have to go to all the
entrances in your house and make sure your doors are all locked is no more.
With voice control. I wish I had this at my place. Supported by Matter and
Thread. You can use your Amazon Echo devices, your HomePod, your Nest Hub,
your Eero devices to just go, "Hey Siri." >> Mhm.
>> lock the door. >> Locking the entrance.
>> Pretty bougie lock. And you can get it on Amazon, actually cheaper than you can
on the Apple Store. So, use our link below to check this thing out today. I
am going to uninstall it so Lion never knows I was even here.
