How to Let Someone In Remotely (Without a Risky Spare Key)
Leaving a spare key under the doormat or a flowerpot is a classic trick, but let's be real, it's a huge security risk. Physical keys can be lost, copied, or found by the wrong person, and you'll never know who has used them. It’s time for a smarter, more secure approach to managing access to your home.
This guide explains exactly how to let someone in remotely using modern smart lock technology. We'll cover the main ways to grant access, explain how the technology works, and help you choose the best method for any visitor—from family members to your weekly dog walker.
At SAWHERO, we specialize in secure, easy-to-install solutions that give you complete control over your front door. With the right SAWHERO smart lock, you can say goodbye to spare keys forever and learn how to let someone in remotely with confidence, from anywhere in the world.
Beyond the Spare Key: 3 Proven Ways to Grant Remote Guest Access
Smart locks offer flexible and secure ways to unlock your front door remotely. Instead of a one-size-fits-all physical key, you can provide tailored access that is perfect for the situation. Here are the three most reliable methods when figuring out how to let someone in remotely.
Send a "Virtual Key" Directly to Their Smartphone
A virtual key is a digital credential sent to your guest's phone. Using an app, you can send an invitation that allows them to use their own smartphone as a key. This method offers a high level of control and is well-suited for trusted, tech-savvy guests.
Brands like August and Level allow you to set specific permission levels, like "Owner" or "Guest," controlling what they can do within the app. You can also revoke this access instantly at any time, giving you total command over who can enter your home.
Create Temporary or Recurring Keypad Codes
This is arguably the most versatile method for remote guest access. Instead of a key, your visitor simply enters a numeric code on the lock's keypad. This is a great solution because they don't need to download an app or even have a smartphone.
You can create several types of codes for different needs:
- Permanent Codes: For trusted family members and residents.
- Temporary Codes: These expire after a specific date and time, which is ideal for Airbnb guests or contractors.
- Recurring Codes: These only work on specific days and during set hours, perfect for cleaners or dog walkers with a regular schedule.
Many locks from brands like Yale and Schlage can store up to 250 unique codes, and the app's activity log shows you exactly when each code was used. This provides a clear record of everyone who has entered your home. For a deeper dive, learn how to set a smart lock temporary code for secure guest access.
Unlock the Door for Them in Real-Time from Your App
Sometimes, you just need to let someone in right now. For unexpected visits or one-time deliveries, the most direct method is to unlock the door yourself. No matter where you are—at the office or on vacation—you can open your smart lock's app and tap a button to grant immediate access.
This method is ideal for those spontaneous situations where creating a code isn't necessary. A friend drops by to water your plants, or a delivery driver needs to leave a package inside? A quick tap on your phone solves the problem instantly.
The Technology That Makes Remote Entry Possible
Ever wonder how your phone can talk to your front door from miles away? It’s all thanks to a few key wireless technologies working together. Understanding them helps you pick the right lock for your home.
Direct Connection: Wi-Fi and Bluetooth Explained
Most smart locks use a combination of Wi-Fi and Bluetooth. Bluetooth is a low-energy option that works over short distances, typically up to 50 feet. It’s great for unlocking the door when you're nearby but can't provide remote access on its own.
Wi-Fi is what connects your lock to the internet, enabling true remote control from anywhere. Some locks have Wi-Fi built-in, while others use a small Wi-Fi bridge. This device plugs into an outlet and connects your energy-saving Bluetooth lock to your home router, giving you the best of both worlds: long battery life and the ability for how to let someone in remotely.
Smart Home Integration: Z-Wave, Thread, and Matter
Beyond basic Wi-Fi, some locks use mesh networks like Z-Wave or Thread. These create a highly stable, low-power network for your smart home devices but require a central hub like an Amazon Echo or Google Nest Hub to connect to the internet.
The newest standard to know is Matter. It’s a universal protocol that allows devices from different brands to work together seamlessly. A Matter-certified lock is a future-proof investment, ensuring it will work with Apple Home, Google Home, and Amazon Alexa ecosystems for years to come.

Real-Life Scenarios: How People Use Smart Locks to Let Someone In Remotely
The real value of knowing how to let someone in remotely comes to life in everyday situations. Here’s how different people are using smart locks to solve common problems and make their lives easier.
For the Busy Airbnb Host: Automating Guest Check-in
Managing check-ins can be a major headache for vacation rental hosts. As Forbes often highlights, smart locks are a game-changer for this industry. By integrating a lock from a brand like Schlage with their Airbnb account, hosts can automate the entire process. The system automatically generates a unique, temporary code for each guest that activates at check-in and expires at check-out.
This means guests can arrive anytime without the host needing to be there, providing a smooth, 24/7 self-check-in experience. It improves guest satisfaction and frees up countless hours for the host.
For One-Time Deliveries and Contractors: Secure, Temporary Access
How do you let in a plumber for a one-time repair or accept a valuable delivery when you're not home? This is a common challenge where a smart lock shines. Instead of leaving your door unlocked, you can use the real-time remote unlock feature the moment they arrive.
For a contractor working for a few hours, you can issue a temporary code that's only valid for that afternoon. Once the job is done, the code expires, and you never have to worry about a stray key. This provides a secure, auditable way to manage access for short-term service needs.
For the Pet Owner & Home Service User: Secure Access for Dog Walkers and Cleaners
Trusting service providers with a key can feel uneasy. With a smart lock, you can create a recurring code for your dog walker that only works Monday to Friday between 12 PM and 1 PM. You can do the same for your cleaning service on their scheduled day.
The lock’s activity log provides a digital paper trail, confirming exactly when they arrived and left. This gives you complete oversight and peace of mind, knowing your home is secure and your furry friends are cared for.
For Families & Emergencies: Peace of Mind When You're Away
Picture this: your child gets home from school but forgot their key, and you're stuck in a meeting. Instead of panic, you can simply open your app and unlock the door for them. This is a core reason why people want to learn how to let someone in remotely.
Or, if a pipe bursts, you can let a neighbor or plumber in to handle the emergency while you're on your way. This ability to solve problems remotely provides an incredible sense of security. It’s a modern safety net for the unpredictable moments of family life, ensuring you're always in control.
What to Look For in a Smart Lock for Remote Access
Ready to ditch the spare key? When choosing a smart lock, focus on these key features to ensure you get a reliable, secure, and user-friendly device.
Security and Durability First
A lock’s primary job is to be secure. Look for its ANSI/BHMA grade, which rates its strength and durability. According to security experts, Grade 1 is the highest certification for residential security, offering top-tier protection. Models like the Schlage Encode Plus are often praised for this robust defense against tampering.
Easy DIY Installation to Save on Costs
Professional installation can be expensive. Thankfully, most modern smart locks are designed for easy do-it-yourself installation. Many, including those from SAWHERO, can be installed in under 30 minutes with just a screwdriver. For even more simplicity, tech sites like CNET often point to "retrofit" locks like the August Wi-Fi Smart Lock, which only replace the interior part of your deadbolt. Check out our easy DIY installation guide for more tips.
Smart Home Compatibility and Battery Life
To get the most out of your lock, make sure it works with your existing smart home setup, whether it's Amazon Alexa, Google Home, or Apple Home. Choosing a lock that supports the Matter protocol ensures it will work across platforms. For a great all-in-one solution, check out the SAWHERO A1 Smart Lock, which features built-in WiFi and multiple access methods.
Frequently Asked Questions About Letting People In Remotely
How secure are temporary codes for guests?
They are highly secure. Each code is unique, and you control exactly when it expires. Unlike a key, a code can't be copied, and you can delete it from your app at any moment for instant revocation of access, a key benefit of knowing how to let someone in remotely securely.
What happens if my Wi-Fi goes down? Can guests still get in?
Yes. The lock's keypad and Bluetooth functionality work independently of your Wi-Fi connection. As long as your guest has their code or is within Bluetooth range with their virtual key, they can still get in. Only remote features will be temporarily unavailable.
Do my guests need to download an app to use a code?
No, they don't. If you issue a keypad code, the guest only needs to type it into the lock itself. No smartphone or app is required, making it incredibly simple for visitors of any technical skill level.
Can I see a history of who entered and when?
Absolutely. Nearly all smart lock apps feature a detailed activity log. It shows which code or user unlocked the door and at what time, giving you a complete and auditable history of access to your home.
Is it difficult to install a smart lock myself?
Not at all. Most smart locks today are designed for DIY installation, usually requiring only a Phillips head screwdriver. Brands like SAWHERO provide detailed instructions and video tutorials to guide you through the process in about 15-30 minutes.
How to let someone in remotely if they don't have a smartphone?
The best and easiest way is to create a unique keypad code for them. They can enter this code directly on the lock's keypad to gain entry, making it a great solution for anyone without a smartphone.
Embrace Key-Free Convenience Without Compromising Security
Hiding a key is a thing of the past. Smart locks offer a far more secure, flexible, and convenient way to manage access to your home. With virtual keys, temporary codes, and real-time remote unlocking, you have the power to let someone in remotely with complete confidence.
This technology makes life easier, whether you're running a rental property, coordinating with home service providers, or just need to let a family member in. Learning how to let someone in remotely puts you in control, providing peace of mind from anywhere in the world.
