The catch
August Wi-Fi Smart Lock, fourth generation
A separate keypad is needed for code entry.
Side by side
If a compatible existing deadbolt and its outside appearance must stay, the fourth-generation August Wi-Fi lock is the choice. If replacing the deadbolt is acceptable and you want an integrated touchscreen and Apple home key, choose Encode Plus. Each has a built-in WiFi path for its own remote-control app, so an extra bridge is not the main difference.
Before you buy
With August, the key arrangement of a compatible existing deadbolt stays. Encode Plus replaces the deadbolt.
Where this comes from
The compatible exterior cylinder stays in place when the inside actuator is retrofitted.
The catch
A separate keypad is needed for code entry.
The catch
Both the original deadbolt and the exterior hardware get replaced.

The touchscreen comes with Encode Plus.
Here, home key is documented only for Encode Plus.
Built-in WiFi comes with both locks.
In practice
With August, the key arrangement of a compatible existing deadbolt stays. Encode Plus replaces the deadbolt.
The compatible exterior cylinder stays in place when the inside actuator is retrofitted.
No keypad comes in the selected August package. Encode Plus has its touchscreen on the lock.
The manufacturer August offers separate keypad and fingerprint-keypad bundles, which are not the selected standalone ASIN.
Watch control through the app is what August documents, while Encode Plus explicitly supports tapping with Apple home key.
Both locks have built-in WiFi, yet the two documented Watch entry methods use different interactions.

August, AUG-SL05-M01-S01
Phone is among its entry options, and the documented door range is 1.375 to 2 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 | August Wi-Fi Smart Lock, fourth generation | Schlage Encode Plus Smart WiFi Deadbolt with Camelot trim | In practice |
|---|---|---|---|
| Mechanical installation | Interior retrofit on compatible single-cylinder deadbolt | Replacement deadbolt | A physical-key requirement in common is settled before app preferences. |
| Guest-code hardware in selected package | Keypad sold separately | Integrated touchscreen | Code entry on August means an accessory and a mounting position. |
| Apple Watch entry path | August app control | Apple home key tap supported | Watch app control isn’t the same experience as an NFC home key. |
| Native app remote connection | Built-in WiFi through August app | Built-in WiFi through Schlage Home | A separate bridge isn’t needed for either native WiFi path. |
| Outside door appearance | Existing exterior hardware retained | New exterior touchscreen and cylinder | What changes on the outside depends on the installation approach. |
Trade-offs
Change of plan
Go with August Wi-Fi Smart Lock, fourth generation. On a compatible lock, August keeps those parts.
Go with Schlage Encode Plus Smart WiFi Deadbolt with Camelot trim. Both come with Encode Plus.
Neither model fits. That restriction isn’t met by either installation.
Decision guide
The fourth-generation August Wi-Fi lock is for a compatible existing deadbolt and outside appearance that must stay. Encode Plus is for when replacing the deadbolt is acceptable and you want an integrated touchscreen and Apple home key. Because both have a built-in WiFi path for their own remote-control app, an extra bridge is not the main difference.
August may preserve the arrangement, without replacing the outside hardware, when another door or household member uses the same physical key. Run the specific deadbolt compatibility check first. Encode Plus fits a replacement project, in which a new cylinder and touchscreen are expected changes. Confirm any rekeying plan separately and do not assume every existing key can be retained.
When a visitor will arrive with a code, compare August plus the exact compatible keypad against Encode Plus alone, and build a suitable mounting surface and keypad battery maintenance into that plan. A guest invitation in the August app is another way in, but the guest has to follow that app workflow, and it does not create a physical number pad.
Encode Plus is the choice if tapping a compatible Apple Watch against the lock is the daily interaction you want. August can work well when the phone or Watch app, optional auto-unlock and existing keys suit the household. Check the precise feature and do not treat every Apple Home or Watch integration as NFC home key support.
