The black matte coloring was another winning aspect for me. It meshed well into my home decor and offered a more modern feel than most similar models. Due to this, I didn’t have to worry about these locks being an eyesore anywhere within my home.

But the included instructions aren’t beneficial during the installation process. I’d imagine people unfamiliar with door lock installations would have a tough time with the task. Luckily, I was able to rely on my past experiences to get the job done.

Furthermore, I found the included keys to be well-crafted and durable. I was pleased that this model came with three of them as a precaution. I’m known to lose things regularly, making backup keys a necessity for any keyed lockset.

What to Look for When Buying Interior Door Locks

indoor-keypad-door-lock

Choosing the perfect interior door locks will come down to several factors. This section will discuss each of them to ensure this process becomes effortless. In other words, it’ll help make this buying experience as painless as possible.

Door Lock Type

As you can imagine, interior door locks for home security come in various types. Therefore, it can be a bit frustrating to keep track of them without the proper information. But mainly, every interior door lock falls into one of the following three types:

  • Standard Locking Door Levers

Our first option, standard locking door levers, happens to be the most popular. These locks use a standard locking knob on a room’s interior side.

Meanwhile, the door knob’s exterior will have a flat head lock. It’s an essential aspect because it allows for easy unlocking from the outside. It’s a simple matter of using a flathead screwdriver or even a dull kitchen knife when trying to unlock it.

Many homeowners feel more comfortable with this feature as it provides a way to unlock when an emergency occurs. For example, if a person suffers some type of medical issue behind a locked door, this lock would provide an easy way of reaching them.

  • Key Lock

Interior keyed locks offer a much higher degree of privacy. After all, these locks will require a key to unlock and aren’t accessible with a screwdriver. An interior door lock with key locking mechanisms tends to be suited for closets or other storage areas.

The only challenge is keeping track of your key. Anyone who manages to lose their key won’t have any way of unlocking them from the outside.

  • Electronic Locks

For those who don’t want to use keys or pull a thumb turn, an electronic lock is a good option. Features to look for in this type include number of passcodes allowed, battery life, tamper notification, and remote operation. An electronic bedroom door lock or office lock can be useful in some situations.

For instance, I don’t think anyone wants a keypad door lock for their bathrooms. This situation seems rather inconvenient, especially in a family home. But an interior keypad door lock or electronic interior door lock could work wonders for an office and other private areas.

Meanwhile, hand-operated door locks seem like a much better fit for shared living areas. These minor differences are something to think about when choosing your perfect interior door locks.

Ease of Installation

Any interior door lock worth getting will have an easy installation process. It’s not something that should require paying a professional to do. Due to this, every buyer should look into this process before spending money on a lock.

A straightforward way of researching is reading through customer reviews. These resources should provide an idea of what you can expect from the process. You should also take a gander at each option’s manual to ensure it’s not overly complicated.

I would suggest looking into only buying options that come with all required hardware, as well. You don’t want to be purchasing those pieces separately. It could lead to the product not fitting or other similar issues.

Price

Locks for interior doors will have a wide range when it comes to price. Each buyer will need to build a budget based on their particular wants. For instance, people who want an interior combination door locks will require higher ranges than others.

Accounting for these types of details will keep your budget realistic. From there, it can help limit the number of choices to a much lower number. Trust me; constructing a well-developed budget has helped me through several frustrating buying experiences.

Construction Material

Any high-quality door locks will provide a well-crafted construction. In other words, these locks will be made from top-tier, durable materials. It’s one of the primary things every buyer should research before making a final decision.

Otherwise, you’ll end up with a subpar lock that doesn’t offer any security. It’s just a recipe for a disaster and future repairs.

Who Makes the Top-Rated Interior Door Locks

How Can I Make My Interior Door More Secure

  • Purchasing a door security bar
  • Using a wedge or door stopper
  • Reinforcing the door with a stronger strike plate
  • Build a barricade using tools around your home
  • Set up security cameras

How to Change Interior Door Locks

The process of changing interior door locks will differ from type to type. However, if you read through the manuals and the provided instructions, I doubt the process will be too complex. These resources should make the procedures relatively painless.

Conclusion
