TEEHO TE011W WiFi Keypad Deadbolt, Smart Locks for Front Door…

What fitsThe TEEHO TE011W is listed as a WiFi keypad deadbolt in satin nickel, a finish that usually signals a standard US residential profile rather than a commercial heavy-duty unit.

What to checkFor a thin apartment door, the critical spec is the backset measurement, which must align with the existing 1-1/8 inch hole spacing to avoid drilling new holes into the frame.

eufy Security Smart Lock Familock E32, Fingerprint Keyless Entry…

What fitsThe eufy Familock E32 is a fingerprint keyless entry door lock, and the model number E32 often denotes a specific regional or standard US variant.

Lockin Veno Solar Fingerprint Smart Lock, Deadbolt Only, Runs on…

What fitsThe Lockin Veno is described as a deadbolt-only lock that runs on sunlight, which implies a self-contained power system that may have a different internal layout than battery-only models.

What to checkThis design choice can affect the overall depth of the lock, so you must ensure it fits within the standard 1-1/8 inch backset without extending beyond the door edge.

Kucacci Smart Lock Key Fob, IC Card, 4 Pack

What fitsThis Kucacci listing is for a 4-pack of IC card key fobs, not a complete lock unit, so it is only relevant if you already have a compatible Kucacci smart lock installed.

What to checkThe title specifies IC card compatibility, which is a specific technology that does not guarantee fitment with your existing 1-1/8 inch backset door hardware.

Lockly Guard Secure Pro Deadbolt Smart Lock with 0.3s AI Fingerprint

What fitsThe Lockly Guard Secure Pro is a deadbolt smart lock with 0.3s AI fingerprint recognition, suggesting a high-speed sensor that may require a specific housing depth.

Worth a second look

SMONET Smart Lock Front Door with Handle, Keyless Entry Door Lock…

What fitsThe SMONET smart lock is listed as a front door lock set with a handle and fingerprint entry, which implies a lever-style mechanism rather than a standard deadbolt.

What to checkThis is a critical distinction because lever locks require a different hole pattern than a 1-1/8 inch backset deadbolt, so this may not fit your existing door without significant modification.

Only if it fits

Nuki Smart Lock Ultra (Euro Profile) Smart Door Lock for European…

What fitsThe Nuki Smart Lock Ultra is explicitly labeled for European doors with a Euro Profile, which is a completely different standard from the US 1-1/8 inch backset.

What to checkThis lock is designed for a specific European door mechanism and will not fit a standard American apartment door without extensive and likely impossible modifications.
