Published Date: Aug 15, 2025

We’ve all had those moments — you’re in the middle of a busy day, and suddenly your door lock stops working. It’s enough to test anyone’s patience, but with a few tools and a bit of knowledge, some fixes are easier than you might expect. In this guide, Sure Lock & Key shares simple, effective methods of how to fix a broken door lock.

Ways to Lock a Closet Door

When you’re thinking about how to lock a closet door, there’s no one-size-fits-all method. The best solution depends on your door type, how often you use the closet, and the level of privacy or security you need. Below are some of the most effective and practical ways to lock closet doors — from basic hardware to smart tech — that work for a variety of home setups.

Hook-and-Eye Latch: Simple Closet Lock

A hook-and-eye latch is one of the simplest and most budget-friendly ways to lock a closet door. It consists of a small hook that fits into an eye screw, keeping the door securely closed.

This setup is perfect for standard hinged doors in low-traffic areas, including hallway and guest room closets, where you just want to keep the door shut. While it doesn’t offer high-level security, it’s a quick, DIY-friendly option for adding a little extra privacy or keeping kids and pets out.

Barrel Bolt: Added Privacy for Hinged Doors

If you’re unsure how to lock a closet with minimal tools, a barrel bolt is a great choice. It mounts on the outside and slides into place with no key required.

Ideal for closets in shared or personal spaces, this type of lock is quick to install ad doesn’t require complex hardware.

Locking Door Knob: Built-In Closet Privacy

If your closet door looks like a typical room entry, a locking doorknob can be a seamless upgrade. These knobs usually feature a push-button or turn-style lock built into the handle.

They’re ideal for bedroom or hallway closets and offer a clean, built-in look. Replacing the old knob is simple and gives you a familiar, effective way to lock a closet door with minimal effort. If you’d like a quick refresher, we’ve put together a step-by-step guide on how to install a door knob.

Keyed Entry Knob: Lock with a Closet Door Key

For more control, a keyed knob adds extra protection. It locks from the outside with a closet door key.

Perfect for storing valuables or limiting access in shared homes or home offices, this option offers strong security with a traditional look. Just remember to keep track of the key.

Smart Lock: Keyless Closet Door Access

If you prefer keyless entry, a smart lock could be a great fit for your closet. These locks can be paired with compatible closet doors and controlled through an app or keypad.

They’re a solid option for closets that store sensitive items, electronics, or personal files, especially in tech-forward homes. Just make sure your door supports the hardware and that you’re comfortable with the setup.

Some closet locks are easier to install than others. If you’re unsure about setup, reaching out to a qualified home locksmith is always a smart move. Sure Lock & Key is here to simplify the process — no stress, just a secure fit.

Tension Rod Locks

Perfect for sliding or bifold closet doors, tension rod locks use internal pressure to stay in place. They require no tools and can be set up in minutes — a renter-friendly option with zero damage.
