In an ideal world, your bedroom door would always remain locked. After all, you want to feel safe in the one room in your home. Unfortunately, we don’t live in an ideal world, and there will come a time when you need to lock the door from the inside. An intruder could break into your home, or there could be a natural disaster such as a fire or flood. Whatever the situation, here is how you can install a lock on your bedroom door and make it more secure.

Verify that you can access the screw holes. Drill a second hole with a spade bit through the center of the door’s edge. Screw the bolt into position. Utilizing a wood chisel, insert the faceplate into its corresponding slot.

Drill pilot holes as the third step.

After drilling pilot holes, secure the bolt with the provided screws. So, if you lack access to power tools, you can manually drill.

You are done with a screwdriver to fasten the screws into the plate.

Types of Locks for Bedroom Door

Let’s explore each of them:

Defender Security Lock

The Defender is a small and discrete door stopper that performs well. It can withstand up to 800 pounds of force when locked and positioned in a slot. To unlock, slide the lock up and out of the way.

In contrast to a swing latch or chain, you cannot open the door, and the keyholes cannot be picked. It is reasonably priced, costing less than ten dollars.

Addalock Portable Door Lock

The Addalock dubbed the “original portable door lock,” is the most straightforward and least disruptive suggestion on the list. It functions as a door stopper but is secured to your door using the existing strike plate, eliminating the need for additional hardware or drilling.

Similar to the Defender Security Lock, the Addalock requires a space between the strike plate and the door’s edge. Customers frequently report that this lock does not fit their front doors. So, it is essential to double-check measurements and ensure a proper fit before installation.

August Smart Lock

The third-generation August Home Smart Lock is the most convenient way to acquire a keyless, hands-free door lock for your house or apartment.

Replace the thumb turn on a door with a single-cylinder deadbolt with the August Smart Lock, a battery-powered smart device (keyhole on only one side, not two).

You can unlock the door using Bluetooth and a Wi-Fi-connected hub. So, try using an Amazon Echo or Google Home.

Kwikset Single-Sided Deadbolt

The Kwikset Single-Sided Deadbolt has a blank plate on the exterior and a thumb turn on the interior for your convenience. So, the absence of a keyhole indicates to would-be thieves that you cannot pick your lock.

Although only ANSI grade 3, this lock is compatible with most standard strike plates. It is a fantastic option for apartments with separate entrances but shared common areas.

Kwikset Single-Cylinder Traditional

The Kwikset Single Cylinder Traditional lock is the way to go when you need a reliable lock for your apartment door. It has the highest rating for ANSI cylinder locks (typically used in commercial buildings).

SmartKey locks are resistant to bumping and picking and can be rekeyed by the owner in case of a lost key. Although it is slightly more expensive than a standard deadbolt, we enthusiastically endorse it.

Advantages & Disadvantages of Using Lock


Because there is no keyhole, thieves cannot pick or “bump” the lock, preventing break-ins. Most intruders can now pick standard key locks, improving their ability to break in.

You won’t have to worry about losing or having your keys stolen because you won’t have to carry around a bulky set of keys. In addition, landlords are not required to provide tenants with keys or replace lost ones.

Who is permitted to enter which office building floors are under greater control? In addition, apartment and flat owners and residents can restrict access to their living quarters by assigning a unique PIN to each visitor, thereby making their belongings less desirable as theft targets. The PIN can be modified easily and at any time. Workplace Depot combination locks have over 8,000 possible code combinations and a simple code change mechanism.

There are a variety of contemporary and professional-looking hues available for door locks. The Workplace Depot provides mechanical digital door locks in brass, chrome, and satin finishes.

The additional investment in a door lock is ideal for the elderly and the disabled, who have difficulty opening doors or using keys.


It’s not uncommon to lose your keys, and it’s just as easy to forget your PIN code for the lock, which can be a problem if you’re in a hurry to enter a room or building when it’s late at night or raining outside.

Remember to maintain a clean lock and a secret PIN: You do not want your home’s security code to become public knowledge, so only share it with trusted individuals. With repeated use, the coating on the lock may wear away, and grimy fingerprints may appear on the buttons. Maintain a clean and well-lubricated lock to prevent unauthorized parties from discovering the code.

Some digital door locks require electricity to function, so you will be unable to enter your home or business if the power goes out. If you invest in a mechanical or battery-powered lock, you won’t be concerned about losing access during a power outage.

You should avoid a digital door lock with a 10-digit PIN code. Better is a digital door lock with fewer digits. Invest in a high-quality lock with a changeable PIN code; pre-set PINs are easily discovered and should be avoided.

Doorknob Locks vs. Chain Locks

Doorknob Locks

  • D-locks are more portable than chain locks because of their diminutive size and weight.
  • D-locks are frequently more difficult for thieves to break into with tools due to their smaller locking circumference than chain locks’ longer length.
  • Typically, a D-shackle lock is thicker than a chain’s links, making it resistant to bolt-cutter attacks.
  • A D-lock provides marginally more significant security for the exact cost as an alternative locking mechanism. So this indicates that the cost of a chain lock is proportional to its heavier metal construction.

Chain Locks

  • The mere presence of a chain lock typically deters an opportunistic thief.
  • The chain links facilitate adaptability and simplicity, enabling you to secure your bicycle to various surfaces. Similarly, it is simple to secure two bicycles (assuming you have a long enough chain).
  • A chain lock is typically heavier and, therefore, less convenient to carry than a D Lock. Hiplok’s wearable chain locks, on the other hand, feature a patented wearable design that enables you to carry the lock around your waist while cycling without restricting your mobility. This may cause you to forget you are carrying a lock!
  • A chain lock is a great way to secure your residence if you have a ground or wall anchor, such as the Hiplok ANKR. Consider purchasing a longer chain if you plan to use your residential lock to secure multiple bicycles (such as the Hiplok HOME).

The most common residential door lock backsets in the United States are 2 3/8 inches and 2 3/4 inches. Depending on your selected backset, your order will come with a 2-3/8- or 2-3/4-inch latch. So, if you measure the distance from the door’s edge to the center of the handle or knob, you’ll have a good idea of what size lock you need. This measurement, which corresponds roughly to the backset, is used to determine the size of a lock or latch.

Expert Opinion

You can also consider installing a deadbolt inside your door for a more secure lock solution. Just make sure you use the appropriate screws and nuts and check to be sure that the door can handle the weight of the deadbolt. It might also be wise to purchase a bolt appropriate for the door.

Consider installing one on your door if your home has a doorknob that lacks a deadbolt. The easiest way to do this is to purchase a deadbolt that has a matching knob.

However, buying a new deadbolt with a keyed cylinder is possible, and you still have the key on your lock. If you can’t find an appropriate deadbolt with a keyed cylinder, you can select one equipped with a keyway. For an added layer of security, you can also consider installing a lock on your bedroom door.
