Pros: Door compatibility (deadbolt fit), Weather resistance
Cons: Two-factor authentication availability, Jam detection
Bluetooth is commonly used for local control and platform pairing; it is generally responsive, but some reviewers note Bluetooth-based control in certain ecosystems can feel slower at times.
Pros: Backset compatibility, Guest Codes and Access
Cons: Keyway quality, Pick/drill resistance (if rated)
Bluetooth was usually discussed as inferior to UWB or as a fallback/local setup path; reviewers favored Thread/UWB for precision and responsiveness.
Pros: Lock/unlock speed, Smart-home integration (Alexa
Cons: Physical attack resistance, Hub requirement
Bluetooth is mentioned as a local fallback and pairing method, helping nearby control even when the internet is down; locksmith reviews call out modern, encrypted Bluetooth as a positive differentiator.
Pros: Hub requirement, Physical attack resistance
Cons: Auto-unlock, Door-sense
Bluetooth is described as both a local control method and a fallback when Wi-Fi drops, with multiple reviews calling the connection quick and practical for local use.
Pros: Value and Price, Lock/unlock speed
Cons: Geofencing
Bluetooth performance is usually fast and stable for in-range control, though at least one review reports occasional trouble discovering the lock on some phones during setup.

Pros: Lock/unlock speed, Access logs
Cons: Door-sense, Jam detection
Bluetooth-first operation is consistent across reviews: local control works, and keypad-to-lock Bluetooth can feel very fast thanks to an always-on link. However, phone-to-lock Bluetooth connection time can add noticeable delay...
Pros: Existing hardware reuse, Battery
Cons: Finish durability, Auto-unlock
Bluetooth control is typically quick and responsive, and several reviewers note it can feel faster than hub-based control; it also underpins proximity features like Auto-Unlock on many configurations.
Pros: Security features (encryption), Two-factor authentication availability
Cons: Warranty and support, Battery
Bluetooth is commonly required for initial setup and for enrolling users at the door, while day-to-day remote control is handled over Wi-Fi.
