Before you even get a smart lock, you need to make sure that your door is cut correctly to take one (most smart locks won't work with mortise-cut doors, for instance). You should also check to be sure that the door is aligned properly with the frame so the smart lock can slide the bolt without resistance.

Also take a look at your doorframe. Is the hole deep enough for the entire bolt? If not, you'll want to get that fixed, too.

All right, so you've got a door that's ready for a keyless smart lock. Here in the CNET Smart Home, we're going to install the Yale Assure Bluetooth Smart Lock. Here's everything that comes in the box.

Here's the back of the exterior. You'll put this in place on y our door and thread that cable through to the other side...

...where it will connect with the interior half. That's where the batteries are kept, so that cable is what keeps the thing powered.

Yale includes a handy cheat sheet to make sure everything will fit in your door. You can find diagrams like this online with some quick Googling -- it's a good idea to double-check them before making a purchase.

You also get a full set of printed-out instructions. And trust me, the process is easier than it looks here.

Your first step: Insert the bolt itself, then screw the faceplate into place. Easy enough.

You'll want to be sure that the turning mechanism sits right in the center of your door's opening. This is also a good time to check and make sure that the bolt will slide smoothly when you lock the door. To do so, just use a flat-head screwdriver to give it a quick turn.

With the bolt in place, your next step is to slide the exterior half of the lock into place. Thread the cable underneath the bolt and on through to the other side.

The exterior will hang a little loose at this point, and that's okay -- we're going to start tightening things up in just a minute.

Now it's time to get the interior of the lock into position. With this Yale lock, you just remove the back plate of the lock interior and screw it into place.

Once it's affixed to the inside of your door, you'll slide those big brass screws into place. They feed through the bolt and into the exterior half of the lock. You'll want to get them nice and tight.

It helps to hold the door and lock like this as you're screwing those bolts in -- otherwise, they'll just push the exterior half of the lock out of place.

Go ahead and remove the battery cover from the exterior of the lock, but don't put the batteries in yet.

Connect the cable to the interior of the lock, then grab your screwdriver.

This is a good moment to give the lock a quick test turn to make sure that the bolt is turning smoothly.

A couple of screws later, and the exterior sits snugly in place.

Next, get those batteries in.

Once you do, the lock should beep, light up or give some other indication that it's correctly powered.

Screw that battery cover back into place, like so.

There you go! You're now the proud owner of a correctly installed smart lock. To set it up, you'll want to download the lock's app and follow the pairing instructions, which will vary from lock to lock.
