TCL D2 Plus Smart Lock: fingerprint deadbolt with built-in doorbell

The TCL D2 Plus is an electronic deadbolt for a front door. It unlocks with a fingerprint, connects straight to home WiFi and includes a doorbell with alerts sent to your phone. It is aimed at households that want keyless entry and remote control without installing a separate hub.

Fingerprint unlocking

TCL says its self-learning AI algorithm unlocks in under 0.3 seconds and improves with use, reading wet, dry or worn fingerprints. Fingerprint sensors in general can struggle with very wet or damaged fingertips, so it is useful to enrol the same finger more than once. For anyone who prefers other methods, the listing mentions unique access codes for guests, so a keypad or similar entry method is part of the design.

WiFi without a hub

Many smart locks use Bluetooth and need a separate bridge for remote access. TCL says the D2 Plus connects directly to your home WiFi and works through the TCL Home app, with no gateway required. That means you can check status, lock or unlock from your phone, and receive notifications when away. Remote access depends on your router and internet connection, so a lock like this is only as reliable as the network behind it.

Doorbell and alerts

The built-in doorbell sends real-time alerts, and TCL says you can see who is at the door and unlock from your phone. This suits households that receive deliveries or visitors while they are out.

Auto-lock and voice control

The lock supports voice commands through Alexa and Google Assistant. It can also lock itself after a delay that TCL says you can set from 5 to 900 seconds, which removes the worry of whether the door was locked. Set the delay long enough that you are not locked out while carrying shopping in or out.

Weather protection and power

The D2 Plus carries an IP55 code, which TCL describes as withstanding rain, dust and extreme temperatures. In general, IP55 means protection from dust and from water jets, not from submersion. It runs on eight AA batteries, which are not included, and TCL says they last up to 12 months. Battery life varies with usage and with how often the lock connects.

Temporary access and rentals

TCL positions the lock for families who want to give a babysitter or housekeeper temporary access, for short-term rental hosts who want self check-in with unique codes, and for frequent travellers who want remote monitoring. Check the app for how access codes and schedules are managed.

Size and fit

The unit is listed at about 6.2 x 2.5 x 1.3 inches (15.7 x 6.4 x 3.3 cm) and weighs 2.1 lb (about 0.95 kg).

What to check before you buy

• Door fit: check the door thickness, bore holes and backset against the manual's requirements.
• WiFi: confirm that your router signal reaches the front door.
• Batteries: you need eight AA batteries, and it is wise to keep spares.
• Backup entry: check how you can enter if the batteries run out or the network is down.
• Voice assistants: if you use Alexa or Google Assistant, check how voice unlocking is protected.
• Installation: follow the manual and local building codes; get a locksmith or installer if unsure.
