The catch
Aqara Smart Lock U100
You need a compatible Aqara hub for remote control and wider automations.
Side by side
U100 pairs Home Key with fingerprint entry and takes thicker doors. Encode Plus gets you remote access over direct Wi-Fi through Schlage Home, with no Aqara hub to add.
Before you buy
Two inches is within the documented thickness range of U100, and the standard Encode Plus range leaves it out.
Where this comes from
Two inches is 50.8 mm, which is under the U100 55 mm maximum. Two inches is over Schlage 1.75 inches by 0.25 inch.
The catch
You need a compatible Aqara hub for remote control and wider automations.
The catch
Android-only homes may never use the feature that sets it apart from Encode, because its main advantage is strongest for Apple users.

Before you replace your deadbolt, see how Aqara U100 and Schlage Encode Plus differ on Apple Home Key, fingerprint entry, remote-access hardware and door thickness.
Which one fits
Just U100 offers both.
Built-in Wi-Fi comes with Encode Plus.
The U100 range covers 50.8 mm.
Both take its place.
In practice
Two inches is within the documented thickness range of U100, and the standard Encode Plus range leaves it out.
Two inches is 50.8 mm, which is under the U100 55 mm maximum. Two inches is over Schlage 1.75 inches by 0.25 inch.
Tapping an Apple device works on both, yet their remote app paths are different.
Set shared Home Key support against hub-mediated Aqara access on U100 and built-in Wi-Fi on Encode Plus.
A household member without a compatible Apple device benefits from a fingerprint option.
Keypad and physical-key fallback are on both. In this pair, only U100 also lists fingerprint entry.

Aqara, DL-D01D
Entry options listed are fingerprint, home-key, keypad and phone, and the documented door range is 1.375 to 2.17 inches thick.

Schlage, BE499WB CAM 619
Documented to fit doors 1.375 to 1.75 inches thick, with home-key, keypad and phone listed as entry options.
Spec by spec
| Spec | Aqara Smart Lock U100 | Schlage Encode Plus Smart WiFi Deadbolt with Camelot trim | In practice |
|---|---|---|---|
| Fingerprint | Built in | Not included | Household members get a biometric option with U100. |
| Remote network | Aqara hub for Aqara remote control | Built-in Wi-Fi for Schlage Home | Accessory budgets aren’t equal. |
| Door thickness | 35 to 55 mm | 1.375 to 1.75 inches | U100 reaches about 2.17 inches. |
| Smart-home route | Zigbee with Matter available through a compatible hub | Apple Home and Schlage Wi-Fi integrations | Matter over Thread is not native on U100. |
Trade-offs
Change of plan
Neither model fits. An interior retrofit plus a separate fingerprint keypad come with U200.
Decision guide
U100 is the pick if you want Home Key and fingerprint entry together or have a thicker door. Encode Plus is the pick if you want direct Wi-Fi remote access through Schlage Home without adding an Aqara hub.
The buyer may be drawn to Home Key while another family member carries an Android phone or no phone at all. For that person, the U100 fingerprint reader adds a routine besides a code. Encode Plus still gives code and key entry, so think about who will really use the biometric option.
With Encode Plus built-in Wi-Fi, the equipment list for Schlage remote access stays short. U100 can work locally without buying its full smart-home setup, though remote Aqara control requires a compatible hub. Before comparing lock-only prices, write down which functions you need on day one.
U100's published thickness range includes a two-inch door, while the Schlage standard range does not. Treat that as an early filter. It does not approve the fit. Backset, bore, trim clearance and smooth bolt movement still need to be checked.
By the numbers
What we found across the smart locks we compare, plus the checked facts behind each finding.
None of the 25 models checked meets all of “Get in by tapping my phone or watch”, “Use a fingerprint to unlock”, “Run it remotely without needing a hub”, and “Install on a door beyond 1 3/4 inches thick”, so the pick goes to the closest practical compromise.
0 models fit, out of 25 checkedAqara Smart Lock U100 lists 2.17 in for documented door-thickness ceiling, 24% more than the 1.75 in on Schlage Encode Plus Smart WiFi Deadbolt with Camelot trim.
How we countedThe count uses each product's current fit ratings for “Get in by tapping my phone or watch”, “Use a fingerprint to unlock”, “Run it remotely without needing a hub”, and “Install on a door beyond 1 3/4 inches thick”. A need with no documented match is not counted.
How we calculatedFigures take the top of each published door-thickness range. Check bore pattern, backset and lock type separately. For context, 18 of 25 models publish comparable figures.
