Can You Lock a Barn Door: Essential Tips for Optimal Security

Barn door locks are crucial for maintaining security and privacy, whether they’re used for interior doors at home or on actual barns. As barn doors continue to grow in popularity, it’s essential to find locking mechanisms that suit your needs and provide you with peace of mind.

Locking a barn door is more difficult than locking a traditional door. In this article, we’ll look at the importance of barn door locks, how their mechanisms work, and the basic types available for you to choose from for home security.

Fundamentals of Locking Mechanisms

Understanding the fundamentals of locking mechanisms is the first step in knowing which lock is suitable for your barn door. Generally, you’ll find two main kinds of locks for barn doors:

  1. Single-sided locks: These locks can only be operated from one side, typically the inside. They’re ideal for situations where privacy is a priority, such as bathrooms or study doors.
  2. Double-sided locks: These locks can be operated from both the inside and outside, often using a key or a security password. They’re more suitable for situations where security is a concern, like doors leading to a shed or storage room.

Basic Types of Locks

Several types of barn door locks are available to ensure security and privacy.

Here’s a brief overview of some of the most common ones:

  • Tear drop latch: This simple yet effective lock involves a teardrop-shaped sliding door lock. It can only lock the barn door from the inside, making it a great option for bathroom barn doors.
  • Surface-mounted slide bolt: Similar to the teardrop latch, this lock is easy to install and typically used for securing doors from the inside. Unlike the teardrop latch, it’s a more elaborate design, ideal for those who want both style and functionality.
  • Barrel slide bolt: This lock includes a cylindrical bolt that slides into a hole on the door jamb. Some newer designs are double-sided, allowing you to lock and unlock the door from both outside and inside of the door using a key or a security password.
  • Surface-mounted bolt: This lock is similar to the barrel slide bolt but comes with a more sophisticated design that’s also easier to install. Like the barrel slide bolt, it can offer security on both sides with the right design.

Specific Locks to Choose From

Hook and Eye Locks


A hook and eye lock is simple yet effective method to lock your sliding barn door. These locks consist of a hook attached to one side of the door and an eye on the other side, allowing you to slide the hook into the eye to keep the door locked. It’s an easy-to-install option and works well for interior barn doors where you need a basic level of privacy.

Sliding Barn Door Locks

You can use a sliding barn door lock for a more secure option. These locks typically feature a latch bolt that slides into a strike plate mounted on the door frame. Properly installed the lock provides enhanced security and makes it more difficult for intruders to open the door.

Hasp Lock and Padlock

Finally, a hasp and padlock setup can effectively secure your barn door, especially for double sliding doors. A heavy-duty hasp should be mounted on the door, while a durable padlock is attached to the hasp to keep the door locked. This method is practical for doors that require a high level of security, such as exterior barn doors or storage areas containing valuable items.

Latch Locks

Latch locks are another option for securing your barn door. They come in various designs, material, and styles, such as flip latches or surface-mounted slide bolts. These locks are easy to install and offer a reasonable level of security for your barn door. To lock the door, simply flip or slide the latch into the receiver on the door frame.

  • Pencil
  • Drill (with drill bits)
  • Screwdriver
  • Level
  • Safety glasses

Special Considerations for Inside and Outside Barn Doors

Locking Options for Exterior Barn Doors

Whether it’s an inside or outside barn door, installing a lock is necessary.

For barn doors from the outside, security is the priority. You should look for locks that are weather-resistant and strong enough to hold up against potential intruders. Some suggestions for locking exterior barn doors are:

  • Single Cylinder Rim Lock: This lock provides good security using a key on the outside and a latch on the inside. It can be locked or unlocked with a key from either side.
  • Surface-mounted Bolt: A more decorative option, this lock works similarly to the barrel slide bolt but is easier to install. It can be opened from both sides and provides a secure way to lock your exterior barn doors.

Considerations for Family and Children

When securing barn doors in your home, it is essential to consider the needs of your family members, especially children. Locking mechanisms should be installed high enough to prevent children from accidentally locking themselves in rooms or accessing potentially dangerous spaces. Some tips for choosing locks with children in mind include:

  • Look for locks with a built-in emergency release or can be easily accessed from both sides in case your child accidentally locks themselves in a room.
  • Utilize combination locks with relatively easy-to-remember codes to prevent children from getting locked out of the rooms.
  • Consider installing locks with built-in safety features, such as child-proof lock covers, to ensure curious kids can’t open doors without supervision.
