Benefits of Installing Door Knobs that Lock on Both Sides

Before getting into the different types of doorknobs that are available to you, it is good to consider the benefits of a doorknob that locks on both sides.

One of the most common reasons that people have for installing doorknobs that lock on two sides is that it is easier to maintain a secure space. Whether you are looking to install a locking doorknob on your home, office, or any other location, the ability to have both convenience and security is always a good thing.

Another benefit that comes from doorknobs that lock on two sides is that they are safer in many ways to the alternatives. Having a doorknob that is keyed on both sides means that without a key, the door cannot be opened by anyone without a key.

They add an extra layer of protection for your home or business, effectively reducing your risk of unwanted entry and possible theft. In fact, replacing single cylinder locks with their double cylinder counterparts can reduce break-ins by 50% or more.

Consider the Risks

While there are many benefits that come with double cylinder doorknobs, there are also some inherent risks that should be taken into consideration. First, having a doorknob that requires a key on both sides can cause problems in emergency situations. In the case of a fire, for example, the added time to locate a key and operate a lock could prove to become problematic.

To solve this problem, many people keep a key in one side of the double cylinder door while they are home. It is vital that an extra key is always kept on hand, should occupants need to exit in case of an emergency. This ensures that the door can be operated with ease and at speed if a situation requires it.

Alternatively, some double cylinder, or keyed entry, door knobs have a button on the inside that can be pressed to unlock the door. Or, other keyed entry door knobs are outfitted with a twist mechanism on one side that allows you to turn to unlock or lock the door.

Before installing a double cylinder doorknob in your residence, check with the local laws and fire safety codes to ensure that you are on the right side of the law.

Types of Doorknobs That Lock on Both Sides

Before buying a doorknob that locks on both sides, consider the style, shape, color, and level of security you require. Will the doorknob be installed on a door facing the outdoors? Will it be installed on a bedroom door? Would you like your locking doorknob to match the other décor of your home?

No matter what you are looking for, there are certainly many fantastic options available to choose from.

1. Double Cylinder Locks

If you are looking for a doorknob that is keyed on both sides, you will need a double cylinder lock. Doorknobs that are keyed on both sides are not always legal for home use and, as a result, can only be found in the commercial section of the home improvement store of your choice.

You can find virtually every doorknob style available in the double cylinder format, including tulip, Tylo Knob, Juno Knob, and much more.

2. Privacy Doorknobs

Many people looking for a doorknob that locks on both sides opt for privacy doorknobs. Especially when installing doorknobs on interior doors, such as bathrooms, bedrooms, offices, etc. This is especially true in locations where installing doorknobs that are keyed on both sides is illegal.

The interior thumb turnkey is far more common in residential properties. These allow for easy access from one side and can be secured with a key from the other. Not only are privacy doorknobs safer in case of emergency, but they are also more convenient than doorknobs that are keyed on both sides.

Alternatives to a Doorknob that Locks on Both Sides

Given that installing doorknobs that lock on both sides on interior doors is not legal in some places, many people wonder if there are any good alternatives. This is also true for anyone considering the safety implications of having door handles that are keyed on both sides. The good news here is that there are many simple alternatives to choose from.

1. Deadbolts

Choosing a double cylinder deadbolt is not the easiest ways to solve the problem. Some are keyed on both sides monitors have you on one side and are turnkey on the other. If you are considering installing a double cylinder deadbolt, the style you choose will be dependent on the reasons you have for installing it in the first place.

If, for example, you need a door that locks on both sides for security reasons might be better to get a deadbolt that is keyed on both sides. On the other hand, if you’re looking to increase the level of privacy, such as in a bathroom, having a deadbolt with a turnkey could be a good solution as it is simple and safe.

2. Latches

Many doors are not made with fittings for deadbolts. That means that if you are not allowed to install doorknobs that are keyed on both sides you would have to buy new doors or have your existing doors modified to allow the deadbolts to be installed.

Latches are a much easier option and can work out very well for most situations. Latches can be used for securing a door from one side but once engaged that door can only be opened from the side that it was locked on.

How to Lock a Pocket Door from Both Sides

Though pocket doors generally do not have door knobs, they have the ability to be locked from both sides. These types of doors are often used in the bathroom, as a way to separate rooms, or anywhere where a traditional swinging door will not fit.

Pocket door locks come in two varieties: passage (non-locking) and privacy (locking). The privacy pocket door lock is the one that allows the door to be locked from both sides. Meant to be space saving, these locks function as a pull, allowing you to slide the door in and out of the pocket. The can be locked from one or both sides and are operated by either using a key or a thumbturn.

Privacy pocket door locks are also outfitted with an emergency release button on the outside, allowing you to easily rescue a child who may have accidentally locked themselves inside a bathroom.
