In the world of smart home electronics, choosing a front-door smart lock usually comes down to how many ways you want to unlock it and how much app control you need. This head-to-head compares the Kucacci Keypad Smart Home Door Lock Keyless App Fingerprint Lock Waterproof with the 7-in-1 Smart Door Lock APP Biometric Fingerprint Touch Password Keyless Keypad.
Quick verdict
Pick the Kucacci for a simpler, more conventional keypad-and-fingerprint lock that is easy to fit on universal/reversible doors. Pick the 7-in-1 if you want TTLOCK app management, temporary visitor passwords, IC card support, and a larger fingerprint capacity. The price gap is only USD 1.85, so the decision really comes down to feature priorities.

Both locks are new, finished in black, and ship with hardware, instructions, and a key.

That difference matters depending on how many people use your door and how often you share access.
Where each product wins
- The Kucacci wins on a lower listed price, a matte black finish, stainless steel material, and universal/reversible handing.
- The 7-in-1 wins on TTLOCK app management, five unlocking methods, a 250-fingerprint capacity, Bluetooth support, and adjustable volume.
If you want a lock that feels like an upgraded traditional deadbolt, the Kucacci is that. If you want a lock that behaves like a smart-home hub, the 7-in-1 is that.
Product notes
Kucacci Keypad Smart Home Door Lock Keyless App Fingerprint Lock Waterproof
The Kucacci lock is the more direct option in this pair. It pairs a keypad with a fingerprint reader, and its features include keyless operation, an electronic design, and a traditional key for backup. The matte black finish and stainless steel material give it a clean, durable look, and the universal/reversible handing is useful if your door swing is not standard. For a front-door lock that does not demand a lot of setup decision-making, this is the easier choice.
The Kucacci's key selling points are keyless entry, easy installation, and a keyed backup, rather than app-based extras. The 7-in-1 is the one that spells out temporary visitor passwords, IC card swiping, and remote unlocking. If those advanced sharing options are important to you, the 7-in-1 is the direction to go.
7-in-1 Smart Door Lock APP Biometric Fingerprint Touch Password Keyless Keypad
The 7-in-1 lock is built around the TTLOCK app, which expands what a smart lock can do after it is installed. It supports fingerprint, password, IC card, app-based remote unlocking, and a mechanical key. You also get Bluetooth support, low-battery reminders, adjustable volume, and a fingerprint capacity of 250, making it a solid fit for households with multiple users or regular visitors.
The 7-in-1 lists a 60mm door thickness, while the Kucacci lists universal/reversible handing. If your door falls inside the 60mm specification, the 7-in-1 gives you the most entry flexibility; if you need a lock that adapts to either swing, the Kucacci has that explicit feature.
Final choice by use case
- For a straightforward keypad-and-fingerprint lock with key backup: Choose the Kucacci.
- For maximum entry methods and app control: Choose the 7-in-1.
- For a door with non-standard handing: The Kucacci's universal/reversible handing is the explicit match.
- For a 60mm door and many users: The 7-in-1's 250-fingerprint capacity and temporary passwords fit best.
