Choosing a door lock within smart home electronics comes down to a practical question: do you want to keep an existing deadbolt, use fingerprints and app controls, or simply enter a code on a door knob? These four options take notably different approaches, so the right choice depends more on the way you want to enter than on a single feature list.
Quick take
The August Home Wi-Fi Connected Smart Keyless Entry Door Lock is the focused choice for an existing-deadbolt setup. The factory-reset August Home Smart Lock 3rd Generation is the lowest-priced option and carries a used condition. The Electronic Smart Door Lock emphasizes TTLOCK app management plus several credential types. YE LOCK's keypad smart door knob centers on changeable entry codes and automatic locking behavior.

August Home, Silver Wi-Fi Connected Smart Keyless Entry Door Lock, Electronic
If your priority is a Wi-Fi connected lock that fits an existing deadbolt, this August Home model is the focused pick. It pairs that setup with electronic, keyless operation, universal/reversible door handing, and an ANSI Grade 1 designation. Choose it when those points matter more than minimizing the listed price. The tradeoff is condition and kit detail: it is open box, and the description states that a battery is not included. Hardware is listed among the included items, while fixings are not supplied.
August Home Smart Lock 3rd Generation Factory reset - Silver ASL-3B
The third-generation August is the lowest-priced entry in this group at USD 39.00 and has a silver, electronic, keyless design. Its factory-reset status makes it a strong match for someone specifically seeking an ASL-3B that can be paired with an account, while supplied fixings add a practical detail. Its limitation is straightforward: it is used, even though the description calls it in great condition. Pick this one when the factory-reset ASL-3B designation and the group's lowest listed price are your central criteria.
Electronic Smart Door Lock APP Fingerprint Card Password Key Home Security Lock
Choose the black Electronic Smart Door Lock when fingerprint access and credential variety are central to the decision. Its TTLOCK app management is listed alongside fingerprint, password, IC-card, temporary-visitor-password, mechanical-key, and remote-unlocking functions. The lock also lists a 250-piece fingerprint capacity and adjustable volume. The important constraint is the stated 60 mm door thickness, which makes that measurement a key part of this option's specification. At USD 62.99, it sits between the August lock prices in the comparison.
Keyless Electronic Entry Door Knob, Keypad Smart Door Knob, Interior D

Its listed automatic locking retractor locks the door after opening for three seconds. That behavior is the main constraint to weigh: choose this option when the stated three-second automatic locking timing suits your entry routine. The listed price is USD 47.79.
