Best Smart Lock Under €160 in Europe: WELOCK Touca51 vs Touca51 Pro

Smart locks are quickly becoming a standard upgrade in modern European homes. From keyless entry to remote access management, today’s users expect more than a traditional cylinder lock can offer.

But finding the right smart lock in Europe is not always straightforward.

Many products are designed primarily for the US market, require complicated installation, or lack compatibility with Euro-profile doors. That’s why more homeowners, Airbnb hosts, and small business owners are turning to WELOCK smart locks—especially the Touca51 series.

The WELOCK Touca51 and WELOCK Touca51 Pro are two of the brand’s most popular smart lock solutions for European doors. Both are designed for easy DIY installation, everyday convenience, and modern smart access. However, they target slightly different users.

The Touca51 is the ideal entry-level smart lock for homeowners upgrading from traditional keys for the first time.

The Touca51 Pro builds on that foundation with advanced access management features designed for Airbnb hosts, rental properties, and commercial spaces.

In this guide, we’ll break down:

• What both smart locks have in common
• The key differences between Touca51 and Touca51 Pro
• Which WELOCK smart lock is best for your needs

What Both WELOCK Smart Locks Have in Common

Although the Touca51 and Touca51 Pro serve different types of users, they share the same core WELOCK experience.

Both are built specifically for European-style doors and focus on making smart access simple, practical, and secure.

Designed for European Doors

One of the biggest advantages of choosing a WELOCK smart lock is compatibility.

Unlike many smart locks built around deadbolt systems common in North America, the Touca51 series is designed for Euro profile cylinders widely used across Europe.

That means:

• Easier installation
• Better compatibility
• No need to replace the entire door
• Cleaner integration with existing hardware

For most users, installation takes only a few minutes and requires no drilling or rewiring.

This is one of the reasons WELOCK has become increasingly popular among apartment owners, renters, and homeowners looking for a non-destructive smart home upgrade.

Multiple Unlocking Methods

Both the WELOCK Touca51 and Touca51 Pro support several convenient ways to unlock the door.

Users can access the lock through:

• Fingerprint recognition
• PIN code
• RFID card
• WELOCK app via Bluetooth

This flexibility makes daily use much easier for families and shared households.

For example:

• Children can use a PIN code
• Seniors may prefer RFID cards
• Daily users can unlock instantly with fingerprints

The fingerprint sensor is fast and responsive, delivering a seamless keyless experience that feels natural from day one.

Smart Home Convenience Without Complexity

One of the reasons many users prefer WELOCK over traditional electronic locks is simplicity.

The Touca51 series focuses on practical smart lock features that improve everyday life without creating unnecessary setup complexity.

Both models offer:

• App-based management
• Battery-powered operation
• Low battery alerts
• Modern minimalist design
• Secure encrypted access

For users entering the smart home ecosystem for the first time, this balance between functionality and usability is especially important.

WELOCK Touca51: The Best Entry-Level Smart Lock for Homes

The WELOCK Touca51 is designed for users who want a reliable smart lock experience at an accessible price.

At a discounted price of €119, it delivers excellent value for European homeowners looking for a practical everyday smart lock.

Why the Touca51 Works So Well for Homes

Most households don’t need enterprise-level access management.

What they really want is:

• Convenient keyless entry
• Easy installation
• Reliable fingerprint unlocking
• Better everyday security

That’s exactly where the Touca51 shines.

It removes the hassle of carrying keys while keeping operation simple enough for every family member to use comfortably.

Affordable Smart Lock Without Sacrificing Quality

Many lower-priced smart locks compromise on reliability or user experience.

The Touca51 avoids that problem by focusing on the essentials users actually care about.

For under €120, users still get:

• Fingerprint unlocking
• PIN code access
• RFID support
• Bluetooth app control
• DIY installation
• Long battery life

That combination makes it one of the strongest value smart locks currently available in Europe.

WELOCK Touca51 Pro: The Smarter Upgrade for Airbnb and Business Use

The WELOCK Touca51 Pro takes the same user-friendly foundation and adds more advanced access management features.

At €159 after discount, it is positioned as the premium upgrade within the Touca51 lineup.

And importantly, it’s designed not only for homes but also for high-frequency and commercial environments.

Temporary Password Support Changes Everything

The biggest functional difference between the Touca51 and Touca51 Pro is temporary password support.

The standard Touca51 does not support temporary access passwords, the Touca51 Pro does.

This single feature dramatically expands how the lock can be used.

With temporary passwords, users can:

• Create time-limited guest access
• Share temporary entry codes remotely
• Set scheduled access periods
• Improve property management efficiency

For Airbnb hosts, this becomes incredibly valuable.

Instead of handing over physical keys, hosts can simply generate a temporary password for each guest stay.

Once the reservation ends, access automatically expires.

Built for Airbnb Hosts

Smart locks have become one of the most practical upgrades for short-term rental properties.

The Touca51 Pro is particularly well suited for Airbnb because it simplifies guest access while improving security and operational efficiency.

Benefits for Airbnb hosts include:

• No in-person key exchange
• Faster guest check-in
• Easier remote management
• Reduced risk of lost keys
• Better access control between bookings

For hosts managing multiple apartments or frequent guest turnover, these features save time every week.

Also Ideal for Small Businesses

The Touca51 Pro is not limited to residential use.

Its advanced access features also make it a smart solution for small commercial spaces, including:

• Offices
• Studios
• Retail spaces
• Clinics
• Shared workspaces
• Warehouses

Instead of managing physical keys for employees, administrators can control access digitally through the WELOCK ecosystem.

That flexibility becomes especially useful when staff access changes frequently.
