What Is A Deadbolt?

A deadbolt, or mortice lock, is a type of traditional lock that offers increased security for residential and commercial properties. Unlike a latch lock, which can be easily bypassed using a flat object, a deadbolt requires a key or thumb turn to lock and unlock it. This makes it much harder for an intruder to force the door open, as the bolt extends deep into the door jamb or strike plate.
There are various kinds of deadbolts, including single-cylinder deadbolts, which are opened with a key from the outside and a thumb turn from the inside, and double-cylinder deadbolts, which require a key to be used on both sides. Although double-cylinder deadbolts offer increased security, they may pose a safety hazard in an emergency, as they may hinder quick exit from the building.
When selecting a new deadbolt for your home, it’s essential to consider whether you will need to replace existing hardware or if your existing deadbolt can be rekeyed. There are several factors to remember, such as material and finish, backset size (the distance between the cross borehole and edge of the door), and handing (whether left-handed or right-handed). Consider adding features like bump resistance, drill resistance, anti-pry shields, or intelligent technology compatibility, depending on your needs.


Types Of Deadbolts

Deadbolts are among the most secure type of locks, and they come in various styles and designs. Here’s what you need to know about selecting the best deadbolt for your needs: 

  • Understand How Deadbolts Work: The mechanism behind a deadbolt is simple but effective when activated. It helps prevent intruders from unlocking or manipulating the door lock without a key. This makes them ideal for protection against burglary attempts and other unauthorized access into your home.
  • Consider Different Types of Locks: Several types of deadbolts are available today, each with advantages. Single-cylinder models require a key on both sides, while double-cylinder models require a key from either side to unlock the door. Consider looking at smart deadbolts that allow users to open doors remotely via smartphone apps or voice activation commands.
  • Pick Your Top Choice: Once you have compared all options and understand how each works, pick out your top choice based on factors such as cost-effectiveness, installation requirements, and compatibility with existing door locks for your home. Consider all relevant factors before making your final decision. This will ensure that you select the best option that suits your security needs.

To summarise, researching various types of deadbolt mechanisms is essential when deciding. Understanding how these devices work will help you choose the appropriate model according to its features, price point, ease of use, and convenience level.


Benefits Of Installing A Deadbolt

Deadbolts are generally more robust than other door locks, making them difficult to force open. A deadbolt’s extra layer of protection adds a deterrent from break-ins. Additionally, several types of deadbolts are available, which can provide increased safety features such as pin codes or intelligent lock technology, depending on your chosen style. We recommend selecting a deadbolt recommended by your local professional locksmiths as the best option for securing your home.
Some of the several benefits of installing a deadbolt on your external doors can be:

  • Increased security: Deadbolts provide extra protection for your home or business. Since they require a key or thumb turn to lock and unlock, they are much harder to pick or force open than a latch lock.
  • Deterrent to burglars: Burglars are likelier to target homes or businesses with weak or easily compromised locks. Installing a deadbolt can be a visual deterrent and make them think twice about breaking in.
  • Peace of mind: Knowing that your doors are secured with a deadbolt can provide peace of mind, especially when you are away from home or business for an extended period.
  • Insurance discounts: Some insurance companies may offer discounts on homeowners or business insurance policies for properties with deadbolt locks installed.
  • Increased property value: Installing a deadbolt on your doors can increase the value of your property, as it is considered a desirable security feature by many homebuyers and business owners.


Factors To Consider When Choosing A Deadbolt

When selecting the proper deadbolt for your home, there are a few key factors to consider. 

Firstly, it is essential to determine what type of locking mechanism best suits your needs and security requirements. Many models have various features, including Wi-Fi connectivity, voice command unlocking, fingerprint scanners, etc. Some people may prefer a primary lock that only requires a physical key. In contrast, others might opt for an electronic version that can be unlocked using their smartphone or other devices.

Considering the deadbolt’s size and material is also essential, as this will affect its durability over time. Steel, brass, and zinc alloy are the most common materials used in these locks. Each offers various degrees of strength depending on how often the door will be opened and closed throughout the day. 

Additionally, some manufacturers provide optional additional security measures such as reinforced strike plates which help protect against forced entry attempts. Lastly, if you plan to install multiple locks around your home, consider purchasing ones that use the same key, so you don’t have to fumble through different keys when trying to unlock your door.


Grading System For Lock Strength

When selecting a deadbolt for your home, it is important to understand the grading system for lock strength. The grading system is usually based on the lock’s resistance to various attacks, such as drilling, picking, and prying. 

  • Grade 1 locks have been tested against these techniques and given the highest rating in terms of security performance. 
  • Grade 2 locks provide adequate protection but may be less resistant than grade 1 models. 
  • Grade 3 locks are suitable only when there is a shallow risk of forced entry or tampering with the lock mechanism.

When considering which type of deadbolt will best suit your needs, you must consider any additional security measures you may need to protect your property and valuables adequately. The locks we’ve discussed rely solely on a keyed cylinder to secure the door handle from being turned from the outside.

However, some deadbolts also feature additional security features such as levers, bolts, and other mechanisms, increasing resistance against picking and bumping.


Keyless Entry Options

Keyless door locks allow homeowners to access their homes without needing a physical key, making it much more difficult for intruders to pick up or break into your home. Keyless entry can be an excellent option for those looking for an additional layer of security. There are several types of keyless entry options available:

  • Keypad locks: These locks have a keypad that allows you to enter a code to unlock the door. They are commonly used on exterior doors of homes and businesses.
  • Smart locks: These locks use Bluetooth, Wi-Fi, or other wireless technology to allow you to lock and unlock your door with your smartphone, key fob, or other devices. Some smart locks also allow you to grant temporary access to guests or service providers.
  • Proximity cards or fobs: These devices use radio frequency identification (RFID) technology to allow access to buildings or rooms. They are commonly used in offices and other secure locations.
  • Biometric locks: These locks use fingerprint or facial recognition technology to allow access. They are commonly used in high-security areas.
  • Access Codes: This type of lock requires users to enter a specific code via the digital touchpad before gaining access to the property. The code must be reset periodically to ensure maximum security.
  • Keyless Door Locks Offer Remote Control Capabilities: With keyless door locks, you can open and close doors remotely using your smartphone or other compatible devices. This allows you to grant remote access to visitors even when you’re not at home without compromising security.

Keyless entry systems offer improved convenience and peace of mind by eliminating the worry of lost keys while providing enhanced security features such as fingertip identification and automatic locking mechanisms. 

Deadbolt Installation Tips & Techniques

Installing a deadbolt lock is an important security measure for any home. Before choosing a deadbolt, consider how easy it will be to install and ensure the locks you select will work with your existing door hardware. Additionally, ensure that the lock or unlock mechanism operates smoothly to quickly control who has access to your home.
Here are some tips and techniques to help you with deadbolt installation:

  1. Choose the right deadbolt: There are various types of deadbolts available, including single-cylinder, double-cylinder, and keyless entry. Assess your security needs and choose the appropriate deadbolt for your door.
  2. Measure and mark: Measure the thickness of your door and the distance from the edge to the center of the doorknob hole to determine the appropriate backset (typically 2 3/8 or 2 3/4 inches). Mark the drilling points for the deadbolt, ensuring they are level and centered.
  3. Drill the holes: Start by drilling a hole in the door edge for the latch assembly using a spade or hole saw bit that matches the size of the latch. Then, drill a hole through the door face for the deadbolt cylinder, ensuring it lines up with the edge hole. Be careful not to hit too deep or fast to avoid damaging the door.
  4. Chisel the door edge: Use a chisel to create a recess for the latch plate on the door edge. Ensure the recess is deep enough for the latch plate to flush with the door edge. Also, chisel out the area for the strike plate on the door frame.
    Install the latch assembly: Insert the latch into the door edge hole, ensuring the bevel faces the door jamb. Attach the latch plate with screws provided by the manufacturer.
  5. Install the deadbolt cylinder: Insert the outside cylinder into the hole on the door face, aligning the spindle with the latch. Attach the inside cylinder (thumb-turn or keyhole) and secure it with the provided screws. Make sure the deadbolt operates smoothly.
  6. Install the strike plate: Position the strike plate on the door frame to align with the latch. Secure it with screws, ensuring it is flush with the door frame.
  7. Test the deadbolt: Close the door and test the deadbolt for proper operation. Ensure it extends and retracts smoothly and the door can be locked and unlocked easily.
  8. Adjust if necessary: If the deadbolt is not functioning smoothly, check the alignment of the latch, strike plate, and cylinder. Make any adjustments required to ensure proper operation.
  9. Clean up and finish: Once the deadbolt is installed and operating correctly, clean up any debris and touch up any paint or finish on the door and frame as needed.

By following these tips and techniques, you can successfully install a deadbolt lock and improve the security of your home or office.


How To Determine The Right Size For Your Door Lock

Size is an essential factor when selecting the proper deadbolt for your home. You must choose a lock that fits correctly to ensure maximum security and prevent break-ins. You’ll need to consider several factors and measurements to determine the right size for your door lock. Here’s a step-by-step guide to help you choose the appropriate door lock size:

  • Door thickness: Measure the thickness of your door using a tape measure. Standard residential doors usually have a thickness of 1 3/8 to 1 3/4 inches (35-45mm), while commercial doors may be thicker. Ensure the lock you choose is compatible with your door’s thickness.
  • Backset: The backset is the distance from the edge of the door to the center of the hole for the doorknob or deadbolt. Common backset measurements are 2 3/8 inches (60mm) and 2 3/4 inches (70mm). Measure the backset on your door and choose a lock that matches this measurement.
  • Borehole diameter: Measure the diameter of the existing borehole (the hole through which the lock cylinder will be inserted). Make sure the lock you select will fit the borehole diameter of your door. Standard borehole diameters are 1 1/2 inches (38mm) or 2 1/8 inches (54mm).
  • Cross bore: Measure the diameter of the cross bore, which is the hole on the edge of the door for the latch or bolt. Standard cross-bore sizes are 7/8 inch (22mm) or 1 inch (25mm). Choose a lock with a latch or bolt that fits the cross-bore size.
  • Strike plate: Measure the height and width of the strike plate recess on the door frame. Select a lock with a strike plate that fits within these dimensions.
  • Lock type: Determine the type of lock you need based on your security requirements. Standard options include deadbolts, keyed entry knobs or levers, privacy, and passage locks. Each type of lock serves a different purpose and has varying levels of security.
  • Aesthetics and Finish: Consider the style and finish of the lock to match the existing hardware on your door and the overall design of your home or office.
  • Brand compatibility: If you prefer a specific lock brand or want to match other locks in your home, check compatibility with your door’s measurements and the lock’s specifications.

Considering these factors and taking accurate measurements, you can determine the right size for your door lock and ensure a proper fit and function.


Cost Considerations For Different Types Of Locks

The cost of deadbolts can vary significantly depending on the type, brand, and features. Here are some cost considerations for different types of deadbolts:

  • Single-cylinder deadbolts are the most common and basic, featuring a keyhole on the exterior and a thumb-turn on the interior. The cost for single-cylinder deadbolts typically ranges from $15 to $50, depending on the brand and materials’ quality.
  • Double-cylinder deadbolts require a key for both the exterior and interior sides of the door, offering added security. However, they can pose a safety risk in case of emergency egress. 
  • Keyless entry deadbolts use electronic keypads, innovative technology, or biometrics for access control. They offer convenience and enhanced security features, such as auto-locking and remote access. Keyless entry deadbolts’ price depends on the technology and features.
  • Smart deadbolts integrate with home automation systems and offer remote access, monitoring, and control via smartphones or other devices. They can also support multiple user codes and temporary access. Smart deadbolt’s cost depends on the type of features and brand.
  • High-security deadbolts are designed to resist forced entry, picking, and drilling. They often feature hardened steel components, reinforced strike plates, and advanced locking mechanisms. High-security deadbolt’s price depends on the brand and security features.
  • Grade ratings are graded by the American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) for quality, durability, and security. Grade 1 deadbolts offer the highest level of protection and durability, followed by Grade 2 and Grade 3. Higher-grade deadbolts tend to be more expensive.
  • Installation cost: If you are uncomfortable installing the deadbolt, you may need to hire a professional locksmith. The installation cost can depend on your location and the complexity of the installation.

When choosing a deadbolt, consider your security needs, budget, and the overall product’s overall value may be tempting to opt for a lower-priced deadbolt, but investing in a higher-quality and more secure option can provide long-term benefits.


How To Replace A Door Knob and Deadbolt Lock (step by step)



Best Practices For Keeping Your Home Secure

When it comes to home security, choosing the proper deadbolt is a critical decision. A properly installed and maintained deadbolt can help keep intruders from entering your home by forcing them to break or cut through metal instead of just pushing open the door. Here are some best practices for keeping your house secure with a deadbolt:

  • Look for features like anti-pick pins that make it harder for thieves to pick the lock and gain entry.
    Consider locks that allow you to control access remotely via an app so you can lock and unlock from anywhere.
    Locks also come in smart versions with additional features, such as detecting when someone tries to force the door open and alerting you on your phone if this happens.
  • Invest in an entire lock system where all doors have multiple layers of protection, including keyless entry systems, motion sensors, and video surveillance cameras.
  • Lock all doors and windows: This may seem obvious, but many burglaries occur because a door or window was left unlocked or open. Make it a habit to check that all doors and windows are locked before leaving the house or going to bed.
  • Deadbolts are more secure than regular locks and can help prevent break-ins. Consider installing a deadbolt on all exterior doors.
  • Smart home security systems can monitor your home for intrusions, fires, and other hazards. They can also send alerts to your smartphone when there is a problem.
  • Motion-activated lights can deter burglars by making it harder for them to approach your home unnoticed. Make sure to keep outdoor lighting well-maintained and in working order.
  • Keep valuables such as jewelry, cash, and electronics out of sight and in a safe or lockbox. If a burglar sees expensive items through a window, they may be more likely to target your home.
  • When you go on vacation, ask a trusted neighbor to collect your mail and packages and park their car in your driveway to make it look like someone is home. Avoid posting about your absence on social media, as this can alert burglars that your home is empty.
  • Security cameras can provide visual evidence of break-ins and deter burglars from targeting your home. Ensure to install cameras in strategic locations, such as entry points and areas with high foot traffic.

Following these best practices can help keep your home secure and reduce the risk of break-ins and other security threats.
