Side-by-Side Comparison
| Spec | Aqara Smart Lock U200 (with Keypad) | eufy Smart Lock E30 |
|---|---|---|
| Price | $169.99 | $169.99 |
| Release Year | 2024 | 2024 |
| Lock Type | Retrofit over the existing deadbolt, plus a separate wireless keypad | Full deadbolt replacement |
| ANSI/BHMA Grade | Not published by the manufacturer — Aqara says only 'BHMA-certified' on the U-series pages without naming a grade or standard | ANSI/BHMA Grade 3 — the lowest of the three residential grades (PCWorld's review states Level 3 on the three-point scale) |
| Keeps Existing Keyway | Yes — the exterior cylinder and your keys stay in place | No — the exterior cylinder and keys are replaced |
| Smart Radio | Matter over Thread plus Bluetooth. No Wi-Fi anywhere in the product | 2.4GHz Wi-Fi and Bluetooth built in; Matter over Thread is advertised |
| Hub or Bridge Required | Yes — a Thread border router per ecosystem (HomePod mini, HomePod 2, Apple TV 4K, or equivalent). Without one there is no remote access and no Home Key | No for the eufy app. Matter needs a Thread border router — and PCWorld could not get Matter pairing to complete on an Apple TV 4K or a SmartThings Station |
| Apple Home Key | Yes, over NFC at the keypad | No |
| UWB Hands-Free Unlock | No — that is the U400 | No |
| Biometrics | Fingerprint, on the exterior keypad unit | Fingerprint reader; PCWorld's reviewer described it as finicky |
| Battery Type | Rechargeable lithium pack in the lock (USB-C); keypad takes 4 x AAA or 12-24V DC wiring | 8 x AA alkaline (included) |
| Claimed Battery Life (months) | 6 | 8✓ |
| Backup Power & Key Override | Your existing exterior key still works; USB-C on the lock body accepts a power bank | Physical key cylinder plus a USB-C emergency power port on the exterior |
| Door Thickness / Backset | Standard US single-cylinder deadbolts via the included adapters; slim-profile US deadbolts may need replacing first, and the keypad must sit within about 6 ft (2 m) of the lock | Standard US single-cylinder deadbolt prep; eufy does not publish a door-thickness range |
| Warranty | 12 months | 12 months |
| Colors | Silver, Black | Black |

Pros & Cons
Aqara Smart Lock U200 (with Keypad)
Pros
- +Apple Home Key, fingerprint and Matter over Thread on a retrofit that keeps your existing keyway — nothing else here does all four
- +Thread sips power, and the lock body recharges over USB-C rather than eating AA cells
- +Works across Apple Home, Google Home, Alexa, SmartThings and Home Assistant through Matter rather than a proprietary cloud
- +Keypad is wireless, so it can be mounted away from the door frame if your deadbolt prep is awkward
Cons
- −No Thread border router means no remote control, no Home Key and no smart-home integration — the hub is not in the box and is not optional
- −Aqara says 'BHMA-certified' but publishes no grade, so you cannot compare its security to a Grade 1 Schlage or Level
- −Long-run reliability is the weak point: the Amazon listing sits at 2.7 stars across ~2,000 ratings, with owners reporting jamming and grinding after a year or so
- −Two batteries to manage — a rechargeable pack in the lock and AAAs in the keypad — with different lives
eufy Smart Lock E30
Pros
- +Wi-Fi is genuinely in the lock — you are not buying a bridge afterwards, unlike most of eufy's older C-series
- +Both fallbacks covered: a keyed cylinder and a USB-C emergency contact
- +Fingerprints are held on the device, not uploaded, and eufy charges no subscription for lock features
- +Eight months on AA cells with no proprietary battery pack to source later
Cons
- −ANSI/BHMA Grade 3 — the weakest residential grade, and a real step down from the Grade 1 locks at $250-$350 here
- −The Matter support on the box did not work in PCWorld's testing across two different Thread hubs; treat it as unproven rather than a feature
- −No Apple Home Key, so iPhone users get app control but not tap-to-unlock
- −The fingerprint reader is the least reliable of the biometric locks in this set
