Doorknobs That Lock On Both Sides

Deciding on the best doorknob that locks on both the inside and outside depends on the reason you need it. When choosing a doorknob, it’s important to consider your needs and find an option that provides the right security.

After all, a locked door is one of the simplest and most effective ways to deter criminals.

By having locking capabilities on the inside and outside of the door, you can have additional security, even if the door is glass or by a window that someone could break to unlock the door from the inside.

While it may seem like an unnecessary expense, investing in the right doorknob is an important step in protecting your property and giving you peace of mind. Let’s take a look at the options available for doorknobs that lock on both sides.

1. Double-cylinder locDouble-cylinder lock

A double-cylinder lock doorknob on of a few different keyed entry doorknobs that has a key mechanism on the inside and outside of the door.

To find this type of doorknob, you will have to check the commercial doorknobs section of your hardware store or a specialty store. This is because these types of door knobs are hardly ever used at residential properties.

A double-cylinder lock makes it more difficult for someone to get out of the property if there is an emergency because they would need to have a key to open the door from the inside as well.

Double-cylinder doorknobs are most likely seen in offices, hospitals, and hotels. If you decide to go with a double-cylinder lock, make sure you have a key for both sides of the lock in case you need to exit quickly.

Double-cylinder door knobs may be illegal in some places, so make sure you check the restrictions in your area and for the building you are securing.

2. Single-cylinder lock

A single-cylinder lock is a type of door lock that uses a single cylinder to open the door. The cylinder is usually located on the outside of the door and is operated by a key.

On the inside of the door, there is a thumb turn that can be used to open the lock without a key. Single-cylinder locks are often used on the exterior side of the door, such as front doors, back doors, and patio doors.

When choosing a single-cylinder lock, it is important to select a high-quality product that is resistant to picking and drilling. Additionally, make sure to choose a model that meets your needs in terms of security and convenience.

3. Privacy doorknobs

Privacy doorknobs

A privacy door knob is one of the most common types of doorknobs that have locking functionality on each side.

These types of doorknobs have a thumb turn lock or a push-button on the interior knob and a small hole on the other side that can be locked or unlocked with a special key pin.

Privacy doorknobs are typically used on entry doors in places such as bathroom doors, bedroom doors, and hallways. However, these types of doorknobs can also be used on any door where you want to have the ability to lock it from both sides.

4. Pocket doors

Pocket doors are a great space-saving solution for smaller rooms, but you may be wondering if it’s possible to lock them from both sides. In short, yes!

A pocket door is a type of door that slides open and closed without swinging outward or inward. Pocket doors are typically used in small spaces where a traditional door would be impractical, such as in closets and bathrooms.

There are a few different ways to lock a pocket door from both sides. First, you can install a locking mechanism on the inside of the door. This can be as simple as a latch that slides into place or a more complex deadbolt system.

Alternatively, you can install a second handle or knob on the outside of the door. This way, you can still lock the door even if you’re not able to reach the inside knob.

Whichever method you choose, be sure to test it out before relying on it to keep your pocket door secure.

Other Security Options

Other Security Options

1. A deadbolt

If security is your primary concern, then you’ll want to consider a deadbolt. A deadbolt is a bolt that cannot be moved except by rotating the knob or key.

The bolt is typically engaged by a mechanism located on the interior side of the door, while the exterior side has a keyhole.

In order for a deadbolt to work properly, it must be installed in a door with hinges that allow the bolt to extend past the strike plate. Otherwise, the bolt will not engage fully, and the door will not be secure.

Deadbolts are one of the most effective ways to secure a door, and they are commonly used in conjunction with other locks, such as doorknob locks or chain locks.

If you are looking for door hardware that requires a key on the inside and outside knob, like the double-cylinder doorknob, the double-cylinder deadbolt is a good option.

Some people pair a double-cylinder deadbolt with a simple lever handle on the inside and outside as opposed to keyed entry door knobs.

If you go with a single-cylinder deadbolt, you will only need a key to lock and unlock the outside knob. The inside knob will have a lever or thumb turn that you use to lock and unlock it.

2. Keyless Entry

A keyless entry doorknob is a type of doorknob that does not require a key to open. Instead, it uses a combination of numbers or symbols that can be entered into a keypad on the doorknob itself.

Keyless entry doorknobs are becoming increasingly popular as they offer a more convenient and secure way to enter a home or office. They are also ideal for people who have trouble using traditional keys, such as those with arthritis.

To use a keyless entry doorknob, simply enter the correct code into the keypad and turn the knob to open the door.

Some doorknobs also have an emergency backup system that allows the door to be opened with a traditional key if the code is forgotten or lost.

3. A keycard lock

A keycard lock is a type of electronic lock that uses a card instead of a traditional key. The card is inserted into a slot on the lock and triggers a release mechanism, allowing the door to be opened.

Keycard locks are used in office buildings, hotels, and other commercial settings. They offer a number of advantages over traditional locks, including ease of use and increased security. For example, keycards can be programmed to allow access only during certain hours or to certain areas of the building.

Additionally, if a keycard is lost or stolen, it can be quickly deactivated, preventing unauthorized access.


If you’re looking for a little more security in your home, there are plenty of options available to you. While some people may opt for doorknobs that lock on both sides, others may choose deadbolts or keycard locks.

Ultimately, it’s up to you to decide what will work best for your needs. If you are merely looking for an alternative to a dummy doorknob in your closet to give you more privacy, a privacy doorknob is likely your best bet.

However, if your door is close to a window, the double-cylinder deadbolt or keyless entry may be the way to go. Did you find this article helpful? Let us know in the comments below!
