A smart lock can do much more than fingerprint or card unlocking.
With the SGUDA App, your smartphone becomes a convenient access management tool—allowing you to remotely control your door lock, manage user access, and check activity logs from one place.

Remote Lock and Unlock

Unlock your door even when you’re away.

If a family member forgets their key, a guest arrives earlier than expected, or someone needs emergency access, there’s no need to rush home.

Simply open the SGUDA App to remotely lock or unlock the door, giving you greater flexibility wherever you are.

Check Your Lock Status in Real Time

With the SGUDA App, you can check your smart lock’s connection and current status without having to be physically present.
Combined with remote control features, managing your door lock while you’re away becomes much easier.

4 Lock Modes

Note: Custom Mode (C) is not available on older lock models.

Your smart lock doesn’t have to operate the same way all day. Choose a mode that fits different situations and daily routines.

Normal Mode (N)

The door automatically locks after closing. Best for: everyday use.

Open Mode (O)

Keeps the door unlocked for easier access.
Ideal for situations such as house parties, office hours, or spaces where people frequently enter and leave.

Private Mode (P)

Restricts access when greater privacy or access control is needed.
For example, an office can use Private Mode during a meeting to restrict access by general staff.

Custom Mode (C)

Set specific operating times based on your needs.

For example, offices can schedule lock operation around business hours, reducing repetitive manual adjustments.

Activity Log

When a smart lock is shared by multiple users, knowing when and how the lock was used can be just as important as controlling who can unlock it.

The Activity Log in the SGUDA App records information such as:

• Door opening and closing activity
• Lock mode changes
• Wi-Fi connection and disconnection
• Locking failures or continuous motor operation alerts

This helps administrators keep track of lock activity over time.
It can be useful for:

• Monitoring household access
• Office employee access records
• B&Bs and rental properties
• Shared spaces with multiple users

User Access & Scheduled Access

User Access

SGUDA smart locks can store up to 100 users.

Access permissions are divided into three levels: Admin, Owner / Master, and Guest, making it easier to control who can access and manage the lock.

Admin

The first person who successfully pairs a smartphone with the lock becomes the Admin.
Each lock can have only one Admin. The Admin cannot be deleted, but Admin access can be transferred to another user’s smartphone.

Recommended for: homeowners, primary household managers, or the person responsible for office access.
The Admin has the highest level of control, including managing Owners and Guests, transferring Admin privileges, and configuring system settings.

Owner / Master

Owners have full everyday access along with basic management permissions.

They can lock and unlock the door, view activity records, and add or remove Guest access. However, they cannot change certain system-level settings or transfer Admin privileges.

Recommended for: family members, spouses, adult children, or office managers.

Guest

Guests only receive permission to unlock the door. They cannot access lock settings or view other users’ activity.There are two types of Guest access:

1. Password Guest: Unlocks the door using an assigned PIN code.
2. Password + App Guest: Can unlock using either a PIN code or the SGUDA App.

Recommended for: visiting family and friends, cleaners, babysitters, B&B guests, or temporary users.

Blocked

The user who’s been blocked has no permission to the door.

Scheduled Access

Instead of sharing one password with everyone or making multiple physical keys, you can assign each user their own access method and permitted access times.

Always

Allows access at any time.

Recommended for: family members or permanent employees.

Schedule

Set specific start and end dates. Access automatically expires when the scheduled period ends.

Up to 3 scheduled time periods can be configured at once.

Example: If a friend is staying over on June 6 and August 8, you can set access for those dates in advance. Their access will automatically expire afterward.

Repeat

Allow access only on specific days and during specific hours each week.

Up to 3 recurring time periods can be configured at once.

Example: If a cleaner visits every Tuesday and Friday afternoon, you can grant access only during those specific periods.

Remove Access Instantly—No Need to Collect Keys or Change the Lock

When a roommate moves out, an employee leaves the company, or a guest checks out, there’s no need to collect a physical key or worry about unauthorized copies.

Simply remove that user’s access through the SGUDA App.

This makes access management faster and reduces the risks associated with lost or copied physical keys.

With SGUDA App, everyday access and user management can all be handled directly from your smartphone.

Built-in Wi-Fi — No Extra Hub Required

Some smart locks require an additional Wi-Fi Bridge or Hub to enable remote features.

SGUDA U-Lock has Wi-Fi built directly into the lock, eliminating the need for an additional Wi-Fi Hub.

Through the SGUDA system, users can:

• Check lock status
• Remotely lock and unlock the door
• View activity logs
• Manage the smart lock

This takes your smart lock beyond simple keyless entry and turns it into a remotely manageable access solution.

As travel and accommodation habits continue to change, self check-in has become increasingly common for Airbnb, vacation rentals, and short-term rental properties. In the post-pandemic era, demand for contactless experiences, flexible arrival times, and remote property management has made it less necessary for hosts to be physically present for every check-in.

Airbnb describes self check-in as allowing guests to access a property without the host being present, using options such as a lockbox, smart lock, keypad, or 24-hour building staff.

While self check-in eliminates many face-to-face key handoffs, hosts still need an effective way to manage guest access.

1. Guests Get Locked Out

A guest arriving late at night may discover that they forgot their key or accidentally left it inside the property.

With a traditional lock, hosts usually need a spare-key plan or someone nearby who can assist the guest.

With a passcode or smart lock, guests do not need to carry a physical key. If remote access is supported, hosts may also be able to help guests enter without traveling to the property.

2. Guests Lose the Key

A lost physical key creates more than an inconvenience. Hosts may need to replace the key and consider whether the missing key creates a security risk.

With a smart lock, hosts can instead change or remove a guest’s passcode or access permission. After checkout, the previous access can be removed and new access created for the next guest.

This is particularly useful for Airbnb and short-term rentals where guests change frequently.

3. The Lock Stops Working

Both traditional and smart locks should have a backup plan in case something goes wrong.

A traditional lock failure may require a locksmith or repair service. When choosing a smart lock, having an alternative such as a mechanical backup key can provide emergency access if electronic functions become unavailable.

How Can Smart Locks Make Self Check-in Easier?

For Airbnb and rental hosts, the main advantage of a smart lock isn’t simply going keyless. It is the ability to manage access for different guests remotely.

For example, hosts can provide a time-limited passcode before arrival, allowing guests to check in without waiting for an in-person key exchange.

Simplify Airbnb & Rental Management with SGUDA

The SGUDA SU-W6 is particularly suitable for Airbnb, vacation rentals, and short-term rental properties where users change frequently.

Before guests arrive, hosts can create time-limited access, while the SGUDA App supports remote passcode management, mobile access permissions, remote lock/unlock, and activity logs. After checkout, access can be changed or removed, reducing the need to exchange, recover, or replace physical keys.

• Wi-Fi Management: Manage check-ins even when you’re abroad!
• Guest Passcodes: Reduce the hassle of handing over access cards.
• Activity Logs: Check whether guests have arrived and accessed the property.
• Emergency Power & Mechanical Key: Access the property even when the batteries run out.

The SGUDA U-Lock features built-in WiFi, allowing users to control and manage the lock directly through their smartphone.

A WiFi smart lock can provide greater convenience, flexibility, and security in everyday life.

Here are three reasons why a built-in WiFi smart lock can be useful.

More Security and Freedom

Traditional keys can create security risks, especially when spare keys are hidden outside the home or shared with multiple people.

A smart lock reduces the need to rely on physical keys. When WiFi connectivity is built directly into the lock, users can also check the lock status and receive activity information through the mobile app.

For homeowners, Airbnb hosts, or users who frequently have cleaners, guests, or family members entering the property, the activity log provides a simple way to understand who has entered or left the home.

This allows users to manage access while maintaining greater visibility over the door.

Let Guests or Friends In While You Are Away

Managing spare keys can become inconvenient, especially for vacation rentals or properties with frequent visitors.

A WiFi-connected smart lock removes the need to duplicate and distribute physical keys.

With built-in WiFi, users can remotely unlock the door through the app as long as an internet connection is available.

This makes it easier to provide access to:

• Family members
• Friends
• Guests
• Cleaning staff
• Rental property visitors

For vacation rental owners, remote access can also simplify the management of multiple properties without requiring someone to physically deliver a key.

Check Whether You Forgot to Lock the Door

“Did I lock the door?”

It is common to leave home and later become unsure whether the door was locked.

With a WiFi-connected smart lock, users can check the lock status directly through their smartphone.

If the door is still unlocked, it can be locked remotely through the app without returning home.

This provides greater convenience and reduces uncertainty when users are away.

Built-in WiFi Without an Additional Hub

Some smart locks require an additional WiFi bridge or hub to enable remote functions.

The SGUDA U-Lock integrates WiFi directly into the lock, allowing users to access connected features without purchasing an additional hub.

Through the SGUDA system, users can remotely manage their lock, monitor activity, and check lock status through their smartphone.

“Can a smart lock get wet?” is one of the most common questions people ask before purchasing a smart lock.

Smart locks contain electronic components, batteries, sensors, and internal wiring. In addition to unlocking methods and smart features, it is also important to consider whether the installation location will be directly exposed to rain or moisture.

Before deciding whether a smart lock is suitable for your door, it is important to understand one thing: waterproof and splash-resistant are not the same.

What’s the Difference Between Waterproof and Splash-Resistant?

In everyday use, the term “waterproof” is often used broadly to describe a product’s ability to resist water. However, the actual level of protection can vary depending on the amount of water, direction of exposure, and duration.

Here is a simple comparison:

A product described as “splash-resistant” is therefore not necessarily designed for prolonged exposure to heavy rain or immersion in water.

If a product has an IP protection rating, its suitability should be evaluated according to the manufacturer’s specified rating and testing conditions rather than relying solely on the term “waterproof.”

Why Does Rain Exposure Matter for Smart Locks?

Smart locks are different from purely mechanical locks.

The exterior and interior units typically communicate through internal wiring and electronic components, while the lock may also contain circuit boards, batteries, and other electronic modules.

Even when a smart lock is designed to handle everyday splashes, prolonged exposure to heavy rain or standing water should still be avoided.

Extra attention should be given to locations such as:

• Outdoor doors without overhead protection
• Entrances exposed to wind-driven rain
• Coastal or high-humidity environments
• Locations where the lock may be directly exposed to water spray

Is an Awning Enough for Smart Lock Installation?

An awning or roof provides useful protection, but it is not the only factor to consider.

The direction of rainfall, wind conditions, and the actual position of the lock should also be evaluated.

For example, even when an entrance has an awning, strong winds may still blow rain directly onto the lock. Long-term exposure to moisture may also affect electronic components.

Before purchasing a smart lock, consider:

Door Type → Installation Location → Direct Rain Exposure → Level of Shelter → Suitable Operating Environment

Evaluating the actual installation environment gives you a much clearer answer than simply asking whether a smart lock is “waterproof.”

How Are SGUDA Smart Locks Designed for Everyday Environments?

SGUDA smart locks are designed with the everyday needs of residential and commercial environments in mind.

Splash resistance does not mean that a smart lock should be continuously exposed to heavy rain or submerged in water.

If you plan to install a smart lock outdoors, in an unsheltered location, or somewhere frequently exposed to heavy rain, we recommend confirming the installation environment and product suitability before purchase and installation.

You can also provide photos of your door and installation location, allowing us to help evaluate whether the door type and environment are suitable.

Beyond Residential Use: Smart Access for Hospitality

For vacation rentals, short-term rentals, and hospitality businesses, the installation environment is only one consideration. Guest access permissions and remote management can also play an important role when choosing a smart lock.

Depending on the product and system requirements, SGUDA smart locks can also be evaluated for integration with a PMS (Property Management System), extending smart access control to self check-in and hospitality management applications.

If you are considering smart access for a vacation rental, hotel, or PMS integration project, share your use case and system requirements with us to discuss potential SGUDA smart access solutions and collaboration opportunities.

The hospitality industry is increasingly moving toward digital and contactless services. Especially in the post-pandemic era, growing demand for flexible check-in and reduced physical contact has encouraged hotels and vacation rentals to rethink traditional front-desk check-in and key card handoffs.

For hospitality operators, going digital is not simply about changing how guests unlock the door. More importantly, it is about simplifying guest self check-in, access management, and daily operations.

Check-in Without Being Tied to the Front Desk

Traditional accommodations usually require front-desk staff or property operators to verify reservations and hand over physical keys or access cards. Late-arriving guests may also require additional staff assistance.

With digital access control, guests can enter their rooms using the access credentials provided before arrival—without waiting for an in-person key handoff.

This is particularly suitable for:

• Vacation rentals and small hotels
• Properties without a 24-hour front desk
• Multi-property operators
• Hospitality businesses looking to introduce contactless check-in

SGUDA: Built-in Wi-Fi for Simpler Access Management

Traditional hotel access control systems may require wiring, additional equipment, and on-site system installation.

SGUDA smart locks feature built-in Wi-Fi, allowing the locks to connect directly to the network without additional wiring. Combined with a cloud-based architecture, this also reduces the need for operators to build and maintain their own on-site servers.

From “Handing Over Keys” to Managing Guest Access

After a guest makes a reservation, operators can create time-limited access credentials before arrival and provide them to the guest in advance.

When guests arrive, they can access their rooms using the assigned credentials without waiting for an in-person key handoff. Once the authorized stay period ends, the guest’s access automatically expires, eliminating the need to collect physical keys or access cards.

The access process can therefore be simplified to:

Create Access → Send to Guest → Guest Self Check-in → Review Activity Logs → Access Automatically Expires

For hospitality operators, a smart lock changes more than just how a door is unlocked. It digitalizes the key handoff and guest access management process that traditionally requires manual handling.

Integrate with PMS to Connect Reservations and Access Management

When smart locks are used independently, operators still need to create guest access permissions for each reservation.

For hotels and vacation rentals managing more rooms or a higher volume of reservations, the next step is to consider integrating smart locks with a PMS (Property Management System).

If the PMS is already connected to booking platforms such as Booking.com or Agoda, integration possibilities can be evaluated based on the actual system and collaboration requirements, allowing reservation data to connect with the SGUDA access management system.

Conceptually, two previously separate workflows:

Booking Platform → PMS → Reservation Management

and

SGUDA → Room Access Management

can be further integrated into a more streamlined hospitality management workflow, reducing repetitive manual entry of reservation details, room assignments, and guest access permissions.
