One To Avoid

JJ. Accessory Touchscreen Smart Lock WiFi Touch Screen Fingerprint Password

We tested the JJ. Accessory Touchscreen Smart Lock with high hopes, given its wide range of unlocking options (fingerprint, keypad, card, app, and key) and support for remote access via WiFi.

It even allows you to monitor unlocking history and offers customisable settings like auto-lock and passage mode. Installation was quick, and we appreciated the USB emergency power option.

However, the positives stop there. This lock showed major durability issues. The fingerprint sensor and keypad became unreliable after regular use, which is a major red flag for a device meant to secure your home.

Battery life was one of the worst we've seen; we had to replace them far too often, sometimes every few days. The app connection was frustratingly inconsistent, and setup through the Tuya platform wasn’t smooth.

Even basic instructions posed challenges, with parts of the interface and manual arriving in Chinese (which made troubleshooting nearly impossible). On top of that, the physical build of the lock felt flimsy, definitely not something we’d trust for a front door.

While the lock sounds impressive on paper, the reality is disappointing. For us, this was one of the least reliable smart locks we've tested. We strongly suggest avoiding it, especially if security and long-term performance matter.

How We Tested and Chose the Best Smart Door Locks on the Market

Finding the best smart door lock takes more than checking specs online. We installed and lived with each lock to assess how well it truly performs across the features that matter most—security, ease of use, smart functionality, and long-term reliability. Here’s how we approached testing smart locks.

Installation and Setup

We began by evaluating how easy each lock was to install using only the tools an average homeowner would have on hand. We timed the process, followed the provided instructions, and checked whether the smart lock features were compatible with standard UK door sizes.

We noted any confusion in the setup guides and whether extra tools or drilling were required.

Access and Unlocking Performance

Next, we tested every available method of access. This included fingerprint recognition, passcode entry, app control, NFC tags, and physical keys. We assessed how quickly and consistently each method worked across multiple users and conditions.

We also checked whether fingerprint sensors worked at various angles and how quickly doors responded to app commands.

Battery Life and Backup Options

Battery performance was monitored over several weeks. We took note of how long each lock lasted on a single charge or set of batteries and whether it offered advanced low-battery warnings.

We also tested most smart locks for emergency access features, such as mechanical key overrides or USB charging ports, to ensure users wouldn’t be locked out.

App Usability and Smart Home Integration

We explored the app experience in detail, how easy it was to set up new users, manage access, view unlock logs, and pair the lock with other smart home platforms. Where available, we tested integration with Alexa, Google Assistant, or Siri to control locks using voice commands.

We also noted whether the remote control was available out of the box or required an additional Wi-Fi gateway.

Build Quality and Security Features

The build of each lock was examined closely. We checked for solid construction using quality materials like zinc alloy and evaluated weatherproofing on models designed for external use.

We applied gentle physical pressure to test for tamper resistance and gauged the keypad or touchscreen's ability to withstand frequent use.

Everyday Practicality

To understand how these locks perform under typical household conditions, we simulated scenarios like arriving home with full hands, letting in guests, or needing to unlock at night or in the rain.

We also evaluated how user-friendly each lock was for children or elderly family members and whether guest access could be easily granted or revoked.

Customer Support and Instructions

We reviewed the clarity of manuals and setup guides, and tested how easy it was to find answers online. When possible, we reached out to customer service teams with questions to evaluate responsiveness and the quality of help provided.

Frequently Asked Questions

Can You Add a Smart Lock to Any Door?

You can add a smart lock to most standard doors, but not every door is compatible. The door must meet certain thickness and latch specifications, and you may need to check whether the lock is designed for internal or external use. Some smart locks also require specific handle or deadbolt types.

Do Smart Door Locks Need Electricity?

Yes, smart door locks need electricity to power features like fingerprint readers, keypads, and Bluetooth or Wi-Fi connectivity. However, they typically run on batteries, not wired electricity. Most models use AA or AAA batteries and include alerts for low power or emergency charging options for backup access.

What Is the Difference Between a Smart Lock and a Digital Lock?

The difference between a smart lock and a digital lock lies in connectivity. A digital lock typically offers keyless entry via a keypad or card but lacks remote features.

A smart lock includes digital access plus app control, user management, integration with voice assistants, and often remote locking/unlocking via Wi-Fi.

Can a Locksmith Open a Smart Lock?

Yes, a locksmith can open a smart lock in most cases. If the lock has a mechanical key override, it can be picked like a traditional lock. For keyless-only models, access may require specialised tools or resetting methods. It’s best to consult a locksmith experienced with electronic locks.

How to Open a Smart Lock with a Dead Battery?

To open a smart lock with a dead battery, use the emergency backup method provided by the manufacturer. This usually includes a mechanical key slot or a USB-C or 9V terminal to temporarily power the lock. It’s important to replace batteries promptly to avoid being locked out unexpectedly.

What Is the Lifespan of a Smart Door Lock?

The lifespan of a smart door lock typically ranges from 3 to 7 years, depending on usage, battery care, and build quality. Regular maintenance, such as cleaning sensors and updating firmware, can help extend its life.

Battery-operated models may last longer with proper battery management and minimal wear.
