Meet the New WELOCK ToucA51 Pro: Smarter Access, More Freedom, Better Control

Smart locks have evolved quickly in recent years, but few upgrades feel as practical as WELOCK’s latest release—the ToucA51 Pro Smart Cylinder.
Designed for modern homes, rental apartments, Airbnb hosts, and anyone who wants a more flexible way to control their door, the ToucA51 Pro brings meaningful improvements in both convenience and security.

Instead of reinventing the smart lock from scratch, WELOCK focused on real-world issues:
✔ How to give guests temporary access without handing over your main code
✔ How to manage your door remotely
✔ How to make installation simple for every household
✔ How to make unlocking faster and more reliable

The result is a clean, elegant upgrade that builds on the success of the ToucA51—but solves the things users cared about most.

Why ToucA51 Pro Stands Out

1. More Ways to Unlock (7-in-1 Functionality)

The Pro model adds a broader range of access methods, including:

• Fingerprint

• PIN code

• Anti-peep virtual PIN

• RFID card

• Temporary passcodes

• App control

• Remote & voice control when paired with WiFiBox3

This level of flexibility is ideal for families, shared spaces, or rental properties.

2. Temporary Passcodes for Visitors & Airbnb

One of the biggest upgrades is the ability to generate temporary, time-limited access codes directly from your phone.
This feature makes check-ins, deliveries, or one-time visits significantly easier—no need to share your permanent PIN.

3. Faster, Smarter Fingerprint Recognition

The ToucA51 Pro uses an enhanced fingerprint sensor that learns from repeated use.
Unlock time is about 0.3 seconds, with improved accuracy even if your finger is wet or slightly misaligned.

4. Simple DIY Installation

Like all WELOCK smart cylinders, the Pro version retains easy installation:

• No drilling

• No wiring

• Fits standard Euro-profile doors

• Typically installed in 5–10 minutes

Even for first-time users, the process is straightforward.

5. Remote Control & Smart Home Integration

When paired with WiFiBox3, the ToucA51 Pro becomes a fully connected smart-home device:

• Lock/unlock remotely

• Receive activity logs

• Use with Alexa or Home Assistant

• Set automation routines

This makes it a strong choice for people who travel often or manage rental units.

The Original ToucA51: Still a Solid Everyday Choice

The previous generation smart lock ToucA51 remains a strong and reliable smart lock.
Its core functions—fingerprint, PIN, RFID, app, and USB emergency power—already meet the needs of typical households.

It’s ideal for users who:

• Want a dependable smart lock at a lower price

• Don’t need temporary passcodes

• Don’t require advanced smart-home automations

• Mainly need fingerprint/PIN convenience

While it doesn’t include some of the advanced features introduced in the Pro version, it remains a good balance between price and everyday functionality.
