Top 8 Sliding Barn Door Lock Ideas

Sliding barn doors come with the inherent challenge of needing a lock added because they don’t come with a handle and strike plate like swing doors. Fortunately, there are several solutions that work well with barn doors.

When selecting a lock, prioritize privacy and security, especially for bathrooms, bedrooms, and home offices. The following are eight of the most popular barn door lock types.

1. Hook-and-Eye Latch

A hook-and-eye latch is a simple, affordable lock for barn doors that provides privacy for anyone on the other side of the door. It consists of a small hook that fits into a screw eye mounted on the door frame.

This lock is ideal for bedrooms, pantries, closets, and other interior spaces where strong security isn’t necessary. Hook-and-eye latches are easy to install with basic tools and are widely available.

2. Privacy Lock With Latch Bolt

Privacy latch bolt locks offer more discretion and are commonly used in bedrooms or bathrooms. This locking mechanism uses a bolt that slides into a catch plate, providing more privacy than a hook-and-eye latch.

This lock is stronger and more reliable than basic latches. It may be operated from one side for added convenience. Its discreet design blends well with modern barn doors. Privacy latch bolt locks are best for primary bedrooms or shared spaces where privacy is important.

Pro Tip: Look for models with soft-close compatibility to protect your barn door’s gliding system.

3. Barrel Slide Bolt Lock

A barrel bolt offers a firm lock and a clean appearance, making it a popular choice for interior barn doors. It features a sliding bolt that fits into a mounted catch on the wall or jamb.

This lock is low-profile, secure, and minimalistic. It comes in various finishes like black matte, bronze, or stainless steel. It’s easy to mount on the inside of the door for invisible security.

Barrel bolts are best for bathrooms and offices that need privacy without exterior access.

Style Tip: Choose a black finish barrel bolt to coordinate with iron barn door hardware for a cohesive look.

4. Keyed Locking Handle

Keyed locking handles offer maximum security and are ideal for rooms requiring restricted access. This lock style combines functionality with a classic door handle, similar to those found on standard swing doors.

This type of lock provides true locking security and adds an upscale touch to any sliding barn door. It works well in shared homes or rental properties. Keyed locking handles are best for home offices, storage rooms, or areas with valuables.

Note: Make sure your barn door has enough clearance for the locking hardware to fully engage.

5. Teardrop or Flip Latch

Teardrop latches, also known as flip latches, offer both function and charm. They use a rotating arm that flips over a catch on the door or frame, keeping the door shut from one side.

They are stylish, vintage-inspired, and easy to use and install. They fit well with rustic and transitional decor. Teardrop latches are best for bathrooms and guest bedrooms.

Design Tip: Opt for aged brass or wrought iron finishes for a timeless appearance.

6. Magnetic Locks

Magnetic locks are sleek and hidden, perfect for minimalist designs. They use magnetic force to keep the door closed and require alignment with the wall mount.

They have no visible hardware and operate silently. This makes them ideal for nurseries and quiet spaces. They offer light security and privacy. Magnetic locks are best for laundry rooms, closets, and children's bedrooms.

Caution: These locks are not for high-security needs but work well for keeping a door closed.

Style Tip: Magnetic locks pair well with modern barn door styles like concealed-rail barn doors for a clean look that blends seamlessly into your wall.

7. Floor-Mounted Drop Bolt

A drop bolt is installed at the bottom of the door and slides into a floor-mounted catch to lock it in place. It’s common in commercial interiors and works well for residential barn doors. It’s discreet, secure, and keeps sliding doors immobile.

Drop bolts are best for securing double barn doors and locking sliding doors when not in use. It’s a great choice when wall space is limited.

Installation Note: Drop bolts require alignment and floor drilling, so they are best for permanent installations.

8. Smart Barn Door Locks

Smart locks add modern convenience to sliding barn doors. Some models are adaptable for sliding doors, including remote-controlled bolt locks and magnetic systems. They offer remote control via smartphone and integrate with smart home systems. They also include notifications and auto-locking features.

Smart locks are best for tech-savvy homeowners and smart homes. They’re also ideal for vacation homes or Airbnbs needing guest access control. Amazon Basics Traditional Keypad, Delaney Touchscreen, and Hugolog Electronic Deadbolt Lock are three of the smart lock models recommended by Consumer Reports.

What to Consider Before Choosing a Barn Door Lock

Choosing the right lock involves thinking about function, safety, and your door's layout.

Think about door overlap and wall clearance to ensure proper fit.
Consider the level of privacy needed. For example, a bathroom needs more privacy than a pantry.
Look for child safety features if you have small children.
Factor in installation tools or handyman costs.
Choose a finish and material that match your door hardware.

Adding a lock to your sliding barn door is a manageable project for most homeowners. If you choose a straightforward mechanism like a hook-and-eye latch, barrel bolt, or flip latch, it’s especially easy. Most locks can be installed in under an hour. Here’s a step-by-step guide to help you get started:

What You’ll Need

Your chosen lock (hook-and-eye, barrel bolt, flip latch, etc.)
Power drill and drill bits
Screwdriver
Measuring tape
Pencil or marker
Level
Screws (usually included with the lock)

Step-by-Step Installation Instructions

Once you have all the necessary materials and tools, follow these steps to install the lock.

1. Mark the Placement

Close the barn door completely.
Use a pencil and level to mark where the lock and catch will be installed on the door and frame (or wall).
Double-check alignment to ensure the lock will engage properly.

2. Pre-Drill Holes

Use the appropriate drill bit to pre-drill holes for the screws. This helps prevent the wood from splitting and makes installation easier.

For barrel bolts, the bolt goes on the door, and the catch goes on the frame or wall.
For hook-and-eye latches, the hook goes on the door and the eye on the frame.

4. Install the Catch or Strike Plate

Align the catch or strike plate with the locking mechanism.
Secure it with screws, ensuring it lines up perfectly for smooth operation.

5. Test the Lock

Open and close the door several times, locking and unlocking to ensure smooth function.
Make any minor adjustments as needed for perfect alignment.

Pro Tips

Use a level to ensure your hardware is straight. This helps with both function and aesthetics.
Paint or stain your hardware to match your barn door for a seamless look.
For heavier or solid wood doors, consider using longer screws for extra stability.
If you’re installing a smart lock, follow the manufacturer’s instructions and ensure you have access to power or batteries as needed.

When to Call an Installation Professional

If you’re installing a keyed lock or a floor-mounted drop bolt, or if your door is especially heavy or valuable, professional installation may be worth the investment for perfect function and peace of mind.
