Side-by-Side Comparison
| Spec | August Wi-Fi Smart Lock (4th Gen, AUG-SL05) | Level Lock Pro (Matter) |
|---|---|---|
| Price | $199.99 | $349.00 |
| Release Year | 2020 | 2025 |
| Lock Type | Retrofit over the existing deadbolt's interior thumbturn | Full deadbolt replacement with the electronics concealed inside the door |
| ANSI/BHMA Grade | Not applicable and not published — the retrofit motor carries no BHMA grade and your existing deadbolt keeps its own | ANSI Grade 1/A, tested to A156.40 (residential deadbolts) and A156.25 (electrified locking), BHMA AAA certified at 250,000 cycles — all stated on Level's own page |
| Keeps Existing Keyway | Yes — the exterior cylinder and your keys are untouched | No — new Level cylinder and keys; your existing key will not work |
| Smart Radio | 802.11 b/g/n Wi-Fi on both 2.4GHz and 5GHz, plus Bluetooth, all inside the lock | Matter over Thread plus Bluetooth 4.0/5.0 and NFC. There is no Wi-Fi radio in the lock |
| Hub or Bridge Required | No — this is the generation that moved Wi-Fi into the lock body. Older August locks needed the separate Connect bridge | Yes — either a Matter-over-Thread hub (HomePod mini, HomePod 2, Apple TV 4K 3rd gen or equivalent) or Level's own Connect Wi-Fi Bridge, sold separately |
| Apple Home Key | No — HomeKit control only, not tap-to-unlock | Yes — tap with iPhone or Apple Watch |
| UWB Hands-Free Unlock | No | No |
| Biometrics | None — there is no keypad and no fingerprint reader in the box | None — and there is no keypad in the box either; the Level Keypad is a separate purchase |
| Battery Type | 2 x CR123A lithium (included) | 1 x CR2 lithium (included), concealed inside the bolt |
| Claimed Battery Life (months) | 3 | 12✓ |
| Backup Power & Key Override | Your existing exterior key always works; August does not publish an emergency power contact on this generation | Two physical keys and two NFC key fobs in the box; there is no emergency power contact, so a flat CR2 means using the key |
| Door Thickness / Backset | Most single-cylinder deadbolts — check August's compatibility list first. Body is 72mm across and 46mm deep on the inside of the door | Door thickness 1.75 in to 2.0 in only, backset 2.375 in or 2.75 in, ANSI 2.125 in bore — the narrowest thickness window of any lock here |
| Warranty | 12 months | 12 months |
| Colors | Silver, Matte Black | Matte Black, Satin Nickel |

Pros & Cons
August Wi-Fi Smart Lock (4th Gen, AUG-SL05)
Pros
- +The only retrofit here with dual-band Wi-Fi in the lock — it will join a 5GHz-only guest network that defeats most rivals
- +DoorSense is still the best-implemented door-ajar sensor in the category
- +Mature HomeKit support and an app that has had a decade of iteration
- +Retrofit install takes minutes and is fully reversible for renters
Cons
- −August's own figure is up to 3 months of battery life, and owners routinely report changing the CR123A cells every 90 days — by far the worst battery economics here
- −CR123A cells cost several times what AAs do, so the running cost is real
- −No keypad, no fingerprint, no Home Key: without your phone you are back to the metal key
- −No Matter support has been published for this generation, and it is a 2020 design at a 2026 price
Level Lock Pro (Matter)
Pros
- +Genuinely invisible: the only lock here that does not announce itself on the outside or bolt a slab of plastic to the inside
- +Publishes ANSI Grade 1/A, BHMA AAA and a 250,000-cycle test figure — the security claims are specific and checkable
- +A single CR2 cell runs it for roughly 9-12 months, so the battery burden is one small cell a year rather than eight AAs
- +Apple Home Key plus two NFC fobs in the box covers guests who do not have an iPhone
Cons
- −The 1.75-2.0 in door thickness limit is the hard trap: plenty of American doors are 1-3/8 in and simply will not take this lock
- −No Wi-Fi in the lock — remote access needs either a Thread hub you already own or Level's Connect bridge as an extra purchase
- −No keypad and no fingerprint in the box; the Level Keypad is another accessory, so out of the box a guest without an iPhone needs a fob or a key
- −$349 with fewer entry methods than an $80 Wyze, and no emergency power contact when the CR2 dies
