How to Replace a Front Door Lock with a Keyed Deadbolt

Why It’s Necessary To Replace Your Front Door Lock?

Elevating your home security by upgrading to a keyed deadbolt for your front door is a transformative step that stands between deterring intruders and succumbing to unwarranted guests.

In the realm of home invasions, an unfortunate reality unfolds, with statistics painting an alarming picture. Consider these thought-provoking numbers:

  • In 2022, the FBI reported a staggering 847,522 burglaries, which is an increase from 2021. And the estimated total value of stolen property due to burglaries in the U.S. was a staggering $463.58 billion.
  • Homes lacking security systems are prime targets, with a 300% higher likelihood of falling victim to burglary.
  • A startling 34% of break-ins occur through the front door, solidifying its standing as the most frequent entry point.

While traditional locks, like keyed ones, have a longstanding presence, they harbor vulnerabilities that expose your home to potential threats. Here’s an insight into these weaknesses:

  • Keys can be swiftly and effortlessly duplicated, granting unauthorized access to your home.
  • Lock cylinders can be easily drilled, rendering the conventional lock ineffective.
  • Traditional locks lack smart features and compatibility with advanced security systems.

By embracing the upgrade to a keyed deadbolt for your front door, you eliminate these vulnerabilities, fortifying your home against potential breaches. It’s a paradigm shift where a superior lock translates to enhanced security and tranquility.

Do I need a keyed door knob if I have a deadbolt?

No, you don’t necessarily need a keyed door knob if you have a deadbolt installed on your exterior door. Here’s a breakdown of the pros and cons:

Benefits of a keyed door knob:

  • Convenience: Allows you to lock and unlock the door from the outside without using a key for the deadbolt.
  • Additional security layer: Can act as a deterrent for casual attempts at entry.

Drawbacks of a keyed door knob:

  • Lower security: Keyed door knobs are generally easier to pick or break into compared to deadbolts.
  • Accidental lockouts: You could potentially lock yourself out if you leave your keys inside and accidentally lock both the knob and deadbolt.

Having a deadbolt alone provides significantly better security than a keyed door knob. Therefore, if security is your primary concern, a deadbolt is sufficient.

However, some people prefer the convenience of a keyed door knob, especially for frequent in-and-out movements. Additionally, in some areas with very low crime rates, the added security of a keyed door knob might be considered unnecessary.

Can I replace a regular lock with a deadbolt?

In most cases, yes, you can replace a regular lock with a deadbolt. However, there are a few things to consider before making the switch:

Door compatibility:

  • Size: Ensure the new deadbolt has the same backset (distance between the center of the knob/lever and the edge of the door) and crossbore (diameter of the hole where the lock cylinder goes) as your existing lock. This information is usually printed on the lock body or packaging.
  • Material: Choose a deadbolt suitable for the material of your door (wood, metal, fiberglass, etc.).

Installation complexity:

  • Pre-drilled holes: Ideally, your door already has the necessary holes drilled for a deadbolt installation. If not, drilling precise holes requires specific tools and skills. Consider seeking professional help if unsure.
  • Door thickness: Ensure the deadbolt’s throw (length of the bolt extending into the door frame) is appropriate for your door thickness.

Additional factors:

  • Security needs: Deadbolts offer significantly higher security compared to regular locks. However, consider your specific security needs and potential vulnerabilities in your home.
  • Aesthetics: Choose a deadbolt that complements the style of your door and existing hardware.

Factors To Consider When Choosing A Keyed Deadbolt Lock

Choosing the right lock for your front door is crucial to maintaining the safety and security of your home. With the different types and brands of door locks available on the market, the process of choosing can be overwhelming.

Here’s what you need to consider when selecting a keyed deadbolt lock:

The Cost Factors Involved In Upgrading Your Front Door Lock

Replacing a front door lock can be affordable or expensive, depending on the type of lock you choose. Here are some cost factors to consider:

  • Quality locks are often pricier than basic models, but they offer stronger security and last longer.
  • Hire a professional locksmith to install your new keyed deadbolt lock to ensure proper installation. Locksmith fees can vary depending on where you live.
  • If you’re installing the new lock yourself, make sure you have the right tools to prevent damage to the door.

Comparison Between Different Door Lock Types And Brands

To determine which type of keyed deadbolt lock works best for you, consider the following:

  • Keyed deadbolt lock: This is a cost-effective option and is the most common type of lock. It requires a key to open and close, and it is perfect for external doors.
  • Smart lock: This is a more modern and convenient option than the traditional lock. You can access it using a key, phone, or even a finger. It also allows for remote access.
  • Knob lock: This is the basic type of lock, and it’s commonly used in residential homes. It requires a key to open, but it’s relatively easy for intruders to break.
  • Brand: Popular brands such as Schlage, Kwikset, and Yale have a reputation for producing high-quality locks. Choose a brand based on your budget and your lock requirements.

Understanding The Different Features Of Keyed Deadbolt Lock

A keyed deadbolt lock is one of the most popular types of locks, but it’s crucial to have a clear understanding of its features. Here are some of its features:

  • Lock grade: The American National Standards Institute (ANSI) grades locks based on their durability and security level. Grade 1 locks are the strongest and most durable, while Grade 3 locks are the most basic and least secure.
  • Keyway: There are different keyways available, including kwikset and schlage. Choose a keyway based on your existing hardware and your specific needs.
  • Finish: Keyed deadbolt locks come in a variety of finishes, such as satin nickel, polished brass, and oil-rubbed bronze. Choose a finish that complements your home’s style.

With these factors in mind, you can choose a keyed deadbolt lock that provides optimum security and increases the aesthetic appeal of your front door.
