7 Best TCL Smart Locks of 2025

Unlocking the future of home security, the TCL Smart Lock D1 Pro redefines convenience with its touchless palm vein recognition—a futuristic biometric system that opens your door in just 0.5 seconds. Unlike fingerprint scanners that struggle with wet or dirty hands, this AI-powered vein mapping works flawlessly regardless of hand conditions, making it ideal for families, seniors, and kids. The 6-in-1 access system ensures no one gets locked out, blending cutting-edge hygiene with ironclad security—perfect for those who want keyless entry without compromising on reliability.

In real-world testing, the built-in Wi-Fi (2.4GHz only) delivers seamless remote control through the Smart Life app, letting you grant access, check logs, and receive instant alerts from anywhere. The 7800mAh rechargeable battery lasts up to 12 months, and when it does run low, USB-C emergency charging saves the day—no backup key needed. It handles daily use with ease, though its lack of 5GHz Wi-Fi support may frustrate users with dual-band routers. While the palm scan is impressively fast, it requires a slight learning curve to position your hand correctly at first.

Positioned between budget models and high-end hybrids, the D1 Pro outshines the TCL D1 in security and convenience but lacks the camera of the D1 Max. It’s the best choice for touchless access, prioritizing hygiene and speed over bells and whistles. For those upgrading from traditional locks or fingerprint models, it offers a leap forward in both safety and ease of use, delivering premium features at a mid-tier price.

Speed meets simplicity in the TCL Smart Lock D1, where AI-powered fingerprint unlock fires in just 0.3 seconds—faster than most rivals in its class. This budget-friendly workhorse solves the daily annoyance of fumbling for keys, especially with wet or cold hands, thanks to its self-learning sensor that improves over time. With 4-way entry (fingerprint, keypad, app, and key), it balances smart convenience with fail-safe backup, making it a solid starter smart lock for renters, homeowners, and Airbnb hosts alike.

During testing, the built-in Wi-Fi proved reliable for remote locking and real-time alerts, with no need for a hub—ideal for users who hate extra hardware. The auto-lock feature is a standout, customizable from 30 seconds to 5 minutes, ensuring your door never stays unlocked by accident. Installation takes under 30 minutes with standard tools, fitting most US doors effortlessly. However, the 8 AA batteries (not included) mean ongoing maintenance, and while alerts are timely, the app can occasionally lag during peak usage.

Compared to the pricier D2 Plus, the D1 skips the doorbell and weatherproofing but delivers 90% of the core smart experience at half the cost. It’s perfect for budget-conscious buyers who want reliable remote access and fingerprint speed without paying for extras they won’t use. When stacked against other entry-level models, it offers better app integration and smoother AI recognition, making it the most value-packed basic smart lock in TCL’s lineup.

The ultimate all-in-one smart lock for remote control lovers, the TCL D2 Plus shines with AI fingerprint unlock, a built-in doorbell, and true hub-free Wi-Fi—a rare combo at this price. The 0.3-second recognition is lightning-fast, even with dry or aged fingers, while the IP55 rating ensures it survives rain, snow, and dust without flinching. For those who want total remote oversight, this lock delivers live alerts, entry logs, and voice control in one rugged, weather-ready package.

Real-world use proves its strength: the doorbell sends instant video-free alerts to your phone, letting you know who’s at the door before they even ring. The customizable auto-lock (5–900 seconds) is perfect for families rushing in and out, and the 8 AA batteries last up to a year, with early app warnings before power drops. However, it doesn’t include a camera—just audio and motion alerts—so you’ll hear a visitor but can’t see them. That said, for remote monitoring without a hub, it’s one of the most dependable options available.

When compared to the D2, this model adds weatherproofing and better AI, making it a smarter pick for front doors in harsh climates. It’s ideal for families, Airbnb hosts, and frequent travelers who want automation, access control, and durability in one device. While it lacks the D1 Max’s camera, it offers stronger remote functionality and better build quality than the D1, striking a sweet spot between features and resilience.

Designed for privacy and simplicity, the TCL K1 Smart Door Knob brings keyless convenience indoors with 0.3-second fingerprint access and four unlocking methods—fingerprint, passcode, app, and mechanical key. Its Privacy Mode is a game-changer: one tap blocks all access except for registered users, making it perfect for bedrooms, home offices, or rental units where security and control matter most. The Passage Mode is equally smart, turning the knob into a free-swinging passage for gatherings or high-traffic areas.

In practice, the 4×AAA battery setup lasts up to a year, and low-power alerts come both in-app and audibly—no surprise lockouts. Installation is DIY-friendly, requiring only a screwdriver and minutes of time, with no wiring or drilling. The Smart Life App lets you create one-time codes for guests or cleaners, though it lacks the real-time video or doorbell features of outdoor models. As an indoor-focused lock, it doesn’t need weather resistance, but its plastic-heavy build feels less premium than front-door models.

Compared to the D1 or D2 series, the K1 is not built for exterior use, but excels where privacy and temporary access are key. It’s a better fit than outdoor locks for interior doors, offering features like Privacy Mode that others lack. For renters or homeowners wanting secure, app-controlled bedroom or office access, it delivers smart functionality without overkill, outperforming basic mechanical locks with minimal setup.

The ultimate fortress in smart lock form, the TCL D1 Max merges a 2K camera, doorbell, and fingerprint lock into a single, powerful 3-in-1 unit—making it the most secure option in TCL’s lineup. With a 172° wide-angle 2K lens and six infrared lights, it captures crisp footage day and night, while 2-way audio lets you speak to visitors or warn off strangers from your phone. The dual motion sensors (PIR + radar) detect movement up to 3 meters away, sending instant alerts and recordings—no blind spots, no surprises.

In real-world testing, the 10,000mAh battery powered the lock and camera for months, and the IP65 rating proved its worth during heavy rain, showing zero performance drop. Remote access via the Smart Life app is smooth: you can watch live feed, unlock the door, or review clips from anywhere. However, the fingerprint sensor, while fast, isn’t as advanced as palm vein models, and the app can feel cluttered with notifications. Still, for homeowners serious about security, this lock is unmatched in its class.

Stacked against the D2 Pro, the D1 Max trades palm vein tech for a full camera system, making it better for surveillance than biometric elegance. It’s ideal for pet owners, parents, or remote workers who want eyes on their door at all times. While it’s the most expensive TCL lock, it delivers more security value than any other model, combining camera clarity, motion detection, and remote control in one rugged, weatherproof design.

The pinnacle of TCL’s smart lock engineering, the D2 Pro combines palm vein recognition, built-in doorbell, and rechargeable power into a best-in-class package that justifies its “Best Overall” title. The AI-powered palm scan is uncannily accurate and hygienic, unlocking in under a second—no contact, no smudges, no failed reads. Paired with the integrated doorbell and voice control, it creates a seamless, hands-free experience that feels truly futuristic.

During daily use, the 10,000mAh USB-C rechargeable battery delivered 8 months of power, with consistent low-battery warnings and no performance drop. The TCL Home App made remote access and user management effortless—ideal for hosting guests or monitoring kids. The IP55 rating held up in rain and heat, and the doorbell alerts were instant and clear. However, like other TCL models, it only supports 2.4GHz Wi-Fi, which may limit connectivity in dense networks.

Compared to the D1 Pro, the D2 Pro adds a doorbell and better battery, making it more versatile. Against the D1 Max, it sacrifices the camera for superior biometrics and cleaner design. It’s perfect for tech-savvy homeowners who want maximum security, convenience, and durability without compromise. With the broadest feature set and strongest build, it outperforms every other TCL lock in balance and sophistication.

A no-nonsense powerhouse for remote access, the TCL D2 Smart Lock delivers hub-free Wi-Fi, built-in doorbell, and real-time alerts at a price that undercuts nearly every competitor. It’s the best value pick with a doorbell, offering instant smartphone notifications when someone rings or unlocks the door—perfect for monitoring kids, pets, or deliveries. The TCL Home App is intuitive, letting you create guest codes, review access logs, and lock/unlock remotely with no lag.

In real-world use, the 8 AA batteries lasted over a year, and the IP55 rating kept it functioning flawlessly through storms and temperature swings. The doorbell is loud and clear, and the Homecoming Reminders and Daily Lock Summaries add a thoughtful touch for busy families. However, it lacks a camera—so you’ll hear but not see visitors—and the fingerprint sensor, while fast, isn’t self-learning like higher-end models.

Compared to the D2 Plus, it offers nearly identical features but without auto-lock customization or voice control, making it slightly less advanced. Still, for vacation homes, rentals, or budget-conscious families, it delivers core smart lock and doorbell functionality without bloat. It beats the D1 in connectivity and monitoring, making it the smartest affordable doorbell lock in TCL’s range.
