What to know before buying

Listing details to confirm

The listing is inconsistent about power: one feature says 8 AA batteries are required and another says 4 AA for standard use, with up to 8 for extended life. Confirm the selected configuration and included batteries. It also describes the lock as a doorbell but does not specify whether this provides video or two-way communication. Door fit depends on the listed thickness and backset measurements, so compare those with your door before ordering.

Aggregate customer ratings lean positive, with the distribution concentrated in the top two star categories and some three-star ratings. This is a small rating sample without written feedback, so it does not identify which features customers liked or any reasons for lower scores. Buyers should assess the claimed access options and verify the battery details independently of the ratings.

Frequently asked questions

Does the TCL D2 need a separate Wi-Fi hub?

The listing says it has built-in Wi-Fi and does not require a hub. It specifies 2.4GHz Wi-Fi and says it works best within 65 ft of the router.

What access methods are listed?

The listing describes app control, touchscreen passcodes, temporary codes, a FOB card and a backup mechanical key. Confirm package contents for the FOB card, since the explicit included-components field only names the smart lock.

How many passcodes can it store?

The feature listing claims up to 50 custom passcodes, including permanent, one-time and time-limited codes.

What batteries does the TCL D2 use?

The listing conflicts: one section says 8 AA batteries, while another says 4 AA for standard use and up to 8 for extended life. Batteries are identified as not included in the feature listing, so check the selected package.

Will it fit my door?

The listing specifies door thicknesses of 1-3/8" or 2-1/8", adjustable backsets of 2-3/8" or 2-3/4", and support for left- and right-handed doors. Measure your door against those figures.
