5 Ways to Childproof Your Home Locks for Safety

August 18, 2025

Keeping your little ones safe at home is every parent’s top priority. While most people think of covering electrical outlets or securing sharp objects, one area that often gets overlooked is locks and doors. Children are naturally curious explorers, and an unlocked or easily accessible door can lead to dangerous situations—like wandering outside, accessing hazardous areas, or even locking themselves inside a room.

Fortunately, childproofing your home locks doesn’t have to be complicated. With a few smart adjustments, you can keep your children safe without compromising the convenience and functionality of your home’s doors. In this article, we’ll explore five effective ways to childproof your home locks for safety.

How to Tell If a Lock Has Been Tampered With

1. Install Childproof Door Knob Covers

One of the simplest and most cost-effective ways to prevent children from opening doors is by using door knob covers. These covers are designed to fit over standard round knobs, making it difficult for little hands to grip and turn them.

How They Work: Adults can still operate the door by squeezing or aligning the cover properly, but kids usually lack the dexterity and strength to figure it out.
Best Use: Perfect for bedroom, bathroom, or front doors where you want to restrict access.
Pros: Affordable, easy to install, and removable when no longer needed.
Cons: May not work on lever-style handles.

Pro Tip: For lever handles, look for lever lock guards that clip over the handle to prevent children from pulling it down.

2. Use Top-Mounted Slide Locks or Latches

Children are surprisingly quick at learning how to open doors, but their height works against them. That’s where top-mounted locks come in handy.

How They Work: Installed at the top of a door, these locks are out of children’s reach. They act as an extra layer of protection, especially on doors leading outside or to dangerous areas (like the garage or basement).
Best Use: Patio doors, entry doors, and any doors leading to unsafe areas.
Pros: Extremely effective since kids can’t reach them.
Cons: Adults need to remember to lock them consistently.

Pro Tip: Choose a sliding bolt or latch that’s sturdy enough to withstand tugging and shaking from curious little ones.

3. Add Childproof Deadbolt Covers

If your doors are equipped with deadbolts, children may try to copy your unlocking routine. Installing a deadbolt cover prevents them from easily turning the lock.

How They Work: The cover is placed over the deadbolt thumb turn, blocking access or requiring a more complex motion that children cannot perform.
Best Use: Front doors, back doors, and any exterior entrances.
Pros: Strong, tamper-resistant, and blends with your existing hardware.
Cons: Some models may be less convenient for frequent use.

Pro Tip: Opt for a sliding shield-style cover, which allows adults to quickly slide it open while keeping kids out.

4. Use Smart Locks with Parental Controls

Technology has made home security smarter—and it can also help with child safety. Smart locks can be managed via smartphone apps, which means you control who can access doors and when.

How They Work: Instead of keys, smart locks rely on codes, apps, or even biometrics. Parents can lock or unlock doors remotely, set specific codes for family members, and monitor lock activity.
Best Use: Main entrances or doors that you want complete control over.
Pros: Provides full parental control, remote monitoring, and eliminates the risk of kids losing keys.
Cons: More expensive than traditional childproofing methods.

Pro Tip: If you install a smart lock, enable notifications so you’re alerted if anyone tries to tamper with or open the door unexpectedly.

5. Secure Sliding Glass Doors with Childproof Locks

Sliding doors are especially tricky because they’re often easier for children to open. Thankfully, there are childproof locks designed specifically for them.

How They Work: These locks prevent the door from sliding open unless disengaged by an adult. Options include sliding door bars, lock clamps, and top-rail locks.
Best Use: Patio doors, backyard entrances, and balcony doors.
Pros: Strong, effective, and can double as an anti-burglary measure.
Cons: May require minor installation.

Pro Tip: Combine a sliding door lock with shatterproof window film to enhance both child safety and home security.

Bonus Tips for Extra Safety

Always keep keys, fobs, and remote controls out of reach.
Teach your children about door safety rules as they grow.
Regularly check locks and childproofing devices to ensure they are working properly.

Final Thoughts

Childproofing your home locks is not just about preventing your kids from running outside or locking themselves in a room—it’s about creating a safe and controlled environment where they can explore without unnecessary risks.

From simple knob covers to advanced smart locks, you have a range of options depending on your budget and needs. By combining a few of these methods, you can enjoy peace of mind knowing your children are safe while still maintaining easy access for adults.

Can You Rekey Smart Locks or Only Traditional Ones?

By Ghulam Mustafa • April 6, 2026

Smart locks promise convenience. Keyless entry. Remote access. Control from your phone. But when it comes to security, one question still confuses many homeowners: Can you rekey a smart lock the same way you would a traditional one? Or are you stuck replacing the entire system? The answer isn’t as simple as yes or no. Because not all locks—smart or traditional—work the same way. And understanding that difference can save you time, money, and unnecessary upgrades. Start With What Rekeying Actually Means Rekeying isn’t about changing the outside of a lock. It’s about altering what happens inside. In a traditional lock, rekeying changes the internal pins so old keys no longer work. The hardware stays the same, but access is completely reset. It’s one of the most efficient ways to regain control—especially after moving into a new home or losing a key. But this process depends on one thing: A physical key mechanism. And that’s where smart locks start to differ. Why Traditional Locks Are Easy to Rekey Standard deadbolts and cylinder locks are built for it. Their internal pin systems are designed to be adjusted, reconfigured, and reset without replacing the entire lock. A locksmith can quickly change the key combination while keeping the same exterior hardware intact. This is why rekeying has always been the go-to solution for restoring security without overspending. It’s simple. Direct. Reliable. And in most cases, it’s all you need. What Makes Smart Locks Different Smart locks aren’t just locks. They’re systems. Some rely entirely on digital access—keypads, apps, or biometrics. Others combine smart features with a traditional key cylinder. That distinction matters. Because you can’t “rekey” something that doesn’t use a physical key in the first place. Instead of pins and tumblers, fully digital locks rely on codes, permissions, and software-based control. So the way you reset access changes completely. Can Smart Locks Be Rekeyed? It Depends on the Type If your smart lock includes a physical key override, then yes—part of it can be rekeyed. The mechanical cylinder inside can be adjusted just like a traditional lock. A locksmith can change the key access without affecting the smart features. But if your smart lock is fully keyless, there’s nothing to rekey. In those cases, security is managed digitally. You simply delete old codes, reset access permissions, or perform a factory reset. No hardware changes required. Just a different kind of control. Why Digital Resetting Replaces Rekeying in Smart Systems With traditional locks, control comes from keys. With smart locks, control comes from access management. Instead of worrying about who has a physical copy, you manage: Who has a code When they can enter How long their access lasts If someone no longer needs entry, you don’t rekey. You remove them. That shift is what makes smart locks powerful—but also why people misunderstand how to secure them properly. When Rekeying Still Matters in a Smart Lock Setup Even if you use a smart lock, the physical key backup shouldn’t be ignored. That override exists for a reason. Power failures. Technical glitches. Dead batteries. In those moments, the mechanical key becomes your fallback. If that key has been copied, lost, or shared in the past, rekeying the cylinder is still essential. Because digital security means nothing if the physical backup is compromised. Should You Rekey or Replace a Smart Lock? Not every situation requires a full replacement. If your concern is access control, resetting codes or permissions is usually enough. If your concern is physical key security, rekeying the cylinder solves the problem. Replacement only becomes necessary when the lock is damaged, outdated, or no longer reliable. The mistake most people make is jumping straight to replacement—when a simple reset or rekey would have done the job. The Hidden Risk: Forgetting Old Access Points Whether it’s a traditional lock or a smart one, the real issue is often the same: Too many people have access. Old tenants. Previous owners. Contractors. Guests. With traditional locks, that risk lives in duplicated keys. With smart locks, it lives in forgotten codes and active permissions. If you don’t actively reset and review access, your lock—no matter how advanced—stops being secure. When to Call a Professional If you’re unsure whether your smart lock includes a rekeyable cylinder, or if it’s not functioning properly, it’s worth getting expert input. A locksmith can assess your setup, identify whether rekeying is possible, and ensure both your digital and physical security layers are aligned. Professionals like Brothers Locksmith often handle hybrid systems, where both smart features and traditional mechanisms need to work together seamlessly. Because real security isn’t about choosing one or the other. It’s about making sure every layer does its job. Final Thoughts Rekeying isn’t outdated. It’s just evolving. Traditional locks rely on it. Smart locks replace it with digital control. And hybrid systems use both. The key is understanding what kind of lock you actually have—and how it manages access. Because security isn’t about the label on your lock. It’s about who can still get in. And whether you’ve taken the time to change that.
