A child-proof front-door deadbolt can add a useful barrier between curious kids and an outside door, while still giving adults convenient ways to enter. The three smart locks below include child-safety settings, but their controls work differently: one requires a PIN for inside access, another adds a child-safety mode, and a third pairs its mode with a camera. Check your door’s fit and make sure everyone in your home can exit safely in an emergency before choosing one.

Dhiedas WiFi Keypad Deadbolt: Flexible Access with a PIN-Based Child Lock
The Dhiedas is a smart deadbolt designed to offer several ways to get through the front door. Its child lock is especially direct: when enabled on the rear panel, the door cannot be opened from inside without the correct four-digit PIN. That gives parents a clear access rule to manage, though it also means adults need to know the code to leave while the setting is active.
Entry options include fingerprint, password, RFID, app, voice control, Apple Watch, and a physical key. The built-in Wi-Fi works on 2.4 GHz networks and does not require a separate gateway, according to the product details. The app is described as supporting remote unlocking, notifications, and access records. An automatic-lock feature and door sensor are also intended to help you keep track of the door’s status.
The lock uses a built-in rechargeable battery rather than replaceable AAA batteries. The manufacturer claims up to 365 days of standby time, but actual battery life can vary with use and settings. The listing says the unit fits standard US doors and can be installed as a DIY replacement with a screwdriver. Before ordering, check the lock’s installation requirements against your existing door and hardware.
This is a strong fit if you want a PIN-controlled child lock and a broad range of adult entry methods. Compared with the Bestkid, it adds Apple Watch and voice access in its listed methods; compared with the Foxlock, it focuses more on access options than camera monitoring. A key consideration is that the inside PIN requirement may be less convenient during a rushed exit, so plan how every adult will use it.
Pros:
- Child lock requires a four-digit PIN for inside opening.
- Offers fingerprint, RFID, app, voice, Apple Watch, keypad, and key access.
- Built-in 2.4 GHz Wi-Fi does not require a separate gateway.
- Rechargeable battery and automatic-lock feature are included.
Cons:
- The child-lock setting may slow down adults who need to exit quickly.
- Wi-Fi support is specified for 2.4 GHz networks only.
Verdict: Choose the Dhiedas if you want a PIN-based inside child lock and the widest mix of listed unlocking options.
Bestkid Keyless Entry Deadbolt: Child-Safety Mode with Multiple Backup Options
The Bestkid smart deadbolt uses a child-safety mode that requires a customizable four-digit password for indoor unlocking. Its description says the mode activates a blue indicator light, while outdoor unlocking remains available. That separation may suit families who want to restrict a child’s ability to open the door from inside without giving up the listed outside entry methods.
Adults can unlock it using a fingerprint, keypad, Wi-Fi, RFID card, or Bluetooth app. The listing specifies capacity for up to 100 fingerprints and 100 RFID cards, along with 20 password sets. It also describes an anti-peeping keypad function, unlock records, notifications, silent and do-not-disturb modes, and countdown auto-lock. These options offer more ways to tailor access than a basic keypad deadbolt, but they also mean there are more settings to configure.
The built-in rechargeable battery is listed as 5,000 mAh, with up to six months of use per charge claimed by the manufacturer. It charges through USB-C, and the product details mention low-battery reminders and emergency charging from a power bank. Two emergency keys are included. The listing also states an IP53 rating and an operating range from -4°F to 113°F; confirm that those specifications suit the door’s exposure and local conditions.
Compared with the Dhiedas, the Bestkid includes emergency keys and describes a more detailed set of app modes, while the Dhiedas lists Apple Watch and voice access. It does not include the Foxlock’s camera features. The main practical trade-off is battery upkeep: plan to monitor the charge and keep the emergency access method available.
Pros:
- Child-safety mode uses a customizable four-digit indoor password.
- Includes fingerprint, keypad, Wi-Fi, RFID, and Bluetooth app access.
- Two emergency keys provide a non-app backup entry method.
- USB-C charging and low-battery reminders are specified.
Cons:
- The manufacturer’s stated battery life is up to six months, so charging is part of ownership.
- Several access and operating modes may take time to set up and manage.
Verdict: The Bestkid is a good match if you want a password-based child-safety mode, several access methods, and physical keys for backup.
Foxlock Smart Lock with Camera: Door Monitoring and Childproof Mode
The Foxlock combines a smart deadbolt with a front-door camera. Its childproof mode is managed in the app and is described as helping prevent children from opening the door from inside. The supplied details do not explain a specific PIN rule for that mode, so check the instructions before buying if you need to know exactly how an adult exits while it is active.
For access, the lock lists app, fingerprint, keypad code, physical key, and remote Wi-Fi unlocking. Its 2K camera has a stated 160-degree wide-angle view, night vision, and two-way audio. The app is described as supporting live video, notifications, and remote lock control. This makes it the most monitoring-focused choice here, but the camera and app features may be unnecessary if your main goal is simply to limit a child’s access to the door.
The lock also has a door sensor intended to detect whether the door is open or closed and support automatic locking. The manufacturer lists a 10,000 mAh rechargeable battery, emergency USB power support, and a backup key. The body is described as aluminum and zinc alloy, with an IP54 rating and Grade 2 security level. The listing says it fits most standard US doors and takes about 15 minutes to install, but confirm compatibility with your own door before starting.
Compared with the Dhiedas and Bestkid, the Foxlock’s main distinction is its built-in camera and two-way communication. Its listed childproof mode is less specific about the inside unlocking process than the PIN-based options on the other two. It may suit a household that wants to see and speak with visitors from the app, provided the camera features and its power needs make sense for your setup.
Pros:
- Combines a childproof mode with a camera, night vision, and two-way audio.
- Offers fingerprint, keypad, app, remote Wi-Fi, and physical-key access.
- Includes a door sensor and automatic-lock feature.
- Lists emergency USB power support and a backup key.
Cons:
- The supplied description does not specify the exact inside access rule for childproof mode.
- Camera and app features may be more than you need for a child-safety-focused lock.
Verdict: Pick the Foxlock if you want a smart deadbolt with door monitoring and camera communication, and you are comfortable confirming how its childproof mode works.
How to Choose a Child-Proof Front Door Deadbolt
Understand How the Child-Safety Mode Works
“Childproof” can describe different controls. The Dhiedas and Bestkid specify that indoor unlocking requires a four-digit PIN or password when the safety setting is on. The Foxlock describes an app-based childproof mode but gives fewer details about how inside access works. Before you choose, read the instructions to understand what an adult must do to exit and whether the setting can be changed quickly.
Keep Emergency Exit in Mind
A lock should not create confusion or a delay when someone needs to leave quickly. Consider who in your household may need to use the door, whether they can remember the required code, and what happens if a phone or the lock’s battery is unavailable. Follow local rules for safe egress, and do not rely on a smart lock as a substitute for supervision or other child-safety measures.
Check Door Fit and Installation Needs
Smart deadbolts may not fit every door or existing lock setup. Compare the product’s stated compatibility with your door and the installation instructions before ordering. The Dhiedas says it fits standard US doors, while the Foxlock says it fits most standard US doors; the Bestkid description calls for calibration after installation. If you are unsure, confirm the measurements and requirements with the manufacturer or a qualified installer.
Choose Access Methods Your Household Will Use
Think about how you and other adults prefer to unlock the door. Fingerprints and keypad codes can offer key-free entry, while RFID cards, apps, voice control, watches, and physical keys provide other options depending on the model. More methods can add convenience, but they may also require extra setup. Choose features that fit your routine rather than paying attention only to the number of options.
Plan for Power and Backup Access
Each lock here uses a rechargeable battery, but the listed capacity and claimed battery life differ. The Bestkid specifies USB-C charging and emergency power-bank charging; the Foxlock lists emergency USB power support; and the Dhiedas describes a built-in rechargeable battery. Check how the lock alerts you to low power and keep any included physical key or compatible backup power option accessible.
Decide Whether You Need Remote Features
Wi-Fi and app features can help with remote access, alerts, and lock records, but they are not essential for every home. The Dhiedas specifies 2.4 GHz Wi-Fi and no separate gateway. The Bestkid lists Wi-Fi and Bluetooth app access, while the Foxlock adds live camera viewing and two-way audio. Consider your network, privacy preferences, and whether you will use those features regularly.
FAQs
Can a child-proof deadbolt stop a child from opening the front door?
These locks offer settings designed to make opening the door harder for a child, but no lock replaces adult supervision. Their specific controls differ, so review how the child-safety mode works and make sure it suits your household.
Which of these locks requires a PIN for inside access?
The Dhiedas says its rear-panel child lock requires the correct four-digit PIN to open from inside. The Bestkid says indoor unlocking in child-safety mode requires a customizable four-digit password. The Foxlock description does not give the same level of detail about its inside unlocking process.
Do these deadbolts need a separate Wi-Fi hub?
The Dhiedas explicitly says its built-in Wi-Fi does not require a gateway and supports 2.4 GHz Wi-Fi. The supplied descriptions for the Bestkid and Foxlock list Wi-Fi features but do not provide the same no-hub detail, so check their setup instructions if this matters to you.
What happens if the battery runs low?
The backup options vary. The Bestkid lists low-battery alerts, USB-C charging, emergency power-bank charging, and two keys. The Foxlock lists emergency USB power support and a backup key. The Dhiedas has a built-in rechargeable battery; check its instructions for the exact low-power procedure and keep access plans in place.
Can I install one of these locks myself?
The Dhiedas describes DIY installation with a screwdriver and says it fits standard US doors. The Foxlock also describes DIY installation for most standard US doors. The Bestkid listing mentions calibration after installation. Check the instructions and your door measurements before deciding whether to install it yourself.
Which option is best if I want to see visitors?
The Foxlock is the only one of these three with a built-in camera, night vision, and two-way audio. The Dhiedas and Bestkid focus on smart entry methods and lock controls rather than camera monitoring.
Final Recommendation
For a straightforward child-safety rule with several adult entry options, the Dhiedas stands out because its inside PIN requirement is clearly described. The Bestkid is a practical alternative if emergency keys and USB-C charging matter to you. Choose the Foxlock if camera monitoring is a priority, but confirm its childproof mode’s exact inside access procedure before buying. Whatever you choose, verify door compatibility and make sure every household member can exit safely.
