Philips Wi-Fi Smart Door Lock At $109.97

A front door you can open hands-free and check remotely

The Philips Wi-Fi Smart Door Lock, model DDL240X-1HW, is built for the everyday juggle of arriving with bags, letting in a housekeeper or a renter, and wanting to know the door got locked behind you. It connects directly to your home Wi-Fi, so no extra hub sits in the hallway just to bridge the lock to your phone.

You get five ways to unlock: the app, a fingerprint, a PIN, a voice assistant, or the physical key. Fingerprint access reads in 0.3 seconds, according to Philips, and the lock stores multiple prints for family and trusted visitors. PIN codes can be permanent, one-time, scheduled, or recurring, which covers guests, sitters, and short stays without handing out a key.

We'd consider this a sensible pick if your household already leans on Alexa or Google Assistant and you want the lock to answer to voice commands as well as your thumb. It also reports lock and unlock activity to your phone, so you can see when someone came in rather than wonder.

What $109.97 buys and how the comparison works

At $109.97, this lock sits $24.09 below the typical price over the last 90 days of $134.06, a drop of about 18 percent. It also matches its all-time low, so this is the cheapest we've seen it.

That's a useful gap if you were already shopping this tier of lock. The rating sits at 4.2 from 474 reviews, so there's enough feedback to read through before committing.

Fitting it to your door and keeping it running

The lock comes in Satin Nickel, which tends to sit quietly against most door hardware and paint colors. Since it replaces your existing deadbolt rather than adding a second device, the main fit question is whether your door and frame match what the lock expects.

Auto-lock is the feature most likely to need tuning in daily use. You can set the timer anywhere from 30 to 180 seconds, or hold the keypad for 2 seconds to lock right away. Philips points out that the function depends on having it turned on, a door that has shut completely, and batteries with enough charge, so those three points are worth checking if the bolt ever fails to throw on its own.

The lock runs on batteries, and how often you'll swap them depends on how much traffic your door sees. Check the expected battery type and the low-battery warning behavior before you buy, since those aren't spelled out here. Also confirm the door thickness and backset your entry needs, because a lock that doesn't match your cutout becomes a return rather than an upgrade.

When this lock is the wrong call

Pass on this one if you rent and can't change the deadbolt, or if your building's entry hardware isn't yours to replace. It's also a mismatch if you'd rather not have a lock on your Wi-Fi at all, since the remote access and notifications depend on that connection.

And if you want a keypad-only lock with no app, no fingerprint reader, and no cloud account, you're paying for capability you won't use. For everyone else, the five entry methods and the hub-free setup are the reasons to look here.
