How to Install Deadbolt

Installing a deadbolt can enhance your home's security. Start by choosing a high-quality deadbolt lock.

Use the template provided with the lock to mark the hole positions for the deadbolt and latch. Drill the holes using the appropriate size hole saw and drill bits. Insert the latch into the edge of the door and secure it with screws.


Then, place the deadbolt mechanism through the hole and attach the exterior and interior plates, ensuring they align correctly.

1. Removing an Existing Deadbolt

Removing an existing deadbolt is a crucial step when upgrading your home's security. Begin by dismantling the current deadbolt using a screwdriver and following these simple steps. This process sets the stage for installing a new, robust deadbolt to fortify your door against potential intruders.

2. Determine Deadbolt Placement

Determining the precise placement of a deadbolt is a fundamental aspect of bolstering your home's security. Start by measuring the door's thickness to ensure compatibility with the deadbolt. Next, determine the optimal height for installation, typically around 6 to 12 inches above the doorknob. Consider the door's construction and the deadbolt's design to position it securely within the door.


A well-placed deadbolt reinforces the door against forced entry attempts, offering a reliable defense mechanism. Additionally, take into account any manufacturer-specific recommendations for installation. This step-by-step attention to deadbolt placement ensures not only enhanced security but also a seamless integration that complements your door's structure for maximum effectiveness.

3. Place Your Paper Template

Secure your deadbolt installation success by placing the paper template provided with the lock. Align it precisely on the door according to manufacturer instructions. The template serves as a guide for hole placement, ensuring accurate drilling for the deadbolt components. Taking this initial step guarantees a well-positioned deadbolt, contributing to the overall security of your door and providing a foundation for the subsequent installation steps.

4. Drill Lock Hole

Once your paper template is securely in place, proceed to drill the lock hole, a pivotal step in installing a deadbolt. Utilize a hole saw of the appropriate size, following the markings on the template precisely. Ensure that the drill is level and straight during this process to avoid any misalignment issues. Drilling the lock hole accurately lays the groundwork for seamless deadbolt installation, enhancing the security of your door effectively.

5. Drill Latch Bolt Hole

Following the successful drilling of the lock hole, the next step is to drill the latch bolt hole. Refer to the paper template for the precise location and size of this hole. Use a suitable drill bit to create a hole of the correct diameter, ensuring it aligns with the door frame. This step prepares the door for the insertion of the latch bolt, facilitating smooth operation of the deadbolt lock once installed.

6. Install Faceplate

Following the successful drilling of the lock hole, the next step is to drill the latch bolt hole. Refer to the paper template for the precise location and size of this hole. Use a suitable drill bit to create a hole of the correct diameter, ensuring it aligns with the door frame. This step prepares the door for the insertion of the latch bolt, facilitating smooth operation of the deadbolt lock once installed.

7. Insert Latch Bolt

Carefully insert the latch bolt into the hole drilled in the door, ensuring it aligns with the strike plate on the door frame. Secure it in place using the provided screws. Confirm the smooth operation of the latch bolt before proceeding, ensuring that it extends and retracts easily when the door is opened and closed. This step lays the foundation for a properly functioning deadbolt lock.

8. Install Door Jamb

Secure your deadbolt by attaching the strike plate to the door frame. Align it meticulously with the latch bolt, ensuring smooth operation. Adjust the jamb for a snug fit, fortifying your door against unauthorized access. This step is vital for optimal deadbolt functionality and overall home security.

9. Test the Lock

Conclude your deadbolt installation by thoroughly testing the lock's functionality. Insert the key, turn it in both directions, and confirm the smooth operation of the deadbolt. Ensure that the latch bolt extends and retracts effortlessly when using the door handle. Perform multiple tests to guarantee the lock's reliability, providing you with the peace of mind that your home's security has been effectively reinforced.

Types of Deadbolts

Single-Cylinder Deadbolt:

Operates with a key on one side and a thumb turn on the other, striking a balance between security and convenience. It's easy to use but may pose a security risk if the thumb turn is reachable, making it suitable for doors without adjacent windows.

Double-Cylinder Deadbolt:

Requires a key on both sides, providing heightened security, especially for doors with glass panels.

Offers increased protection, but caution is needed for quick exit during emergencies due to the key requirement on both sides.

Vertical Deadbolt:

Installed vertically, enhancing resistance to forced entry by reinforcing the door frame. It Provides added security by making it more difficult for intruders to pry the door open using common techniques.

Smart Deadbolt:

Integrates technology for remote control and monitoring via smartphones or home automation systems. Keyless entry, remote access, and activity monitoring enhance convenience and security, introducing advanced functionalities for modern home protection.

DIY Deadbolt Installation Vs. Hiring a Pro

Choosing between a DIY deadbolt installation and hiring a professional depends on various factors, including your skill level, time, and budget. DIY installation offers cost savings, typically requiring only the price of the deadbolt lock, averaging $20 to $200.


However, it demands attention to detail and may be time-consuming. On the other hand, hiring a professional locksmith ensures expertise and saves time, but it comes at a higher cost, ranging from $75 to $300, excluding the lock price. Consider your comfort with DIY tasks, the complexity of your door, and your budget constraints when deciding between the hands-on approach and the convenience of professional installation.

Cost to Install a Deadbolt

The cost to install a deadbolt can vary based on whether you choose a DIY approach or hire a professional locksmith. If you opt for a DIY installation, the primary expense will be the deadbolt lock itself, ranging from $20 to $200, depending on the brand and features. On the other hand, hiring a professional locksmith typically comes with a service fee, which can range from $75 to $300.


This fee covers their expertise, time, and tools. Keep in mind that additional costs might arise if your door requires modifications or if you opt for a more advanced smart deadbolt. Consider your budget, skill level, and the level of security you desire when deciding on the most suitable option for your deadbolt installation.

  • Can I Install a Deadbolt Myself?

    Yes, many people successfully install deadbolts themselves. However, it's essential to have basic DIY skills and follow the manufacturer's instructions carefully to ensure proper installation.

  • Can I install a deadbolt on any type of door?

    Deadbolts are versatile and can be installed on various door types. However, certain doors may require additional modifications. Consult the deadbolt manufacturer's guidelines and consider seeking professional help if your door poses challenges.

  • Are smart deadbolts worth the extra cost?

    Smart deadbolts offer added convenience and security features, such as keyless entry and remote monitoring. Whether they are worth the extra cost depends on your preferences and budget. Evaluate the features and benefits to determine if a smart deadbolt aligns with your home security needs.

It happens to the best of us. You're running late, juggling groceries or half-awake on your way to work, and before you realize it—the door clicks shut, and your keys are inside. Getting locked out isn’t just inconvenient—it’s stressful, time-consuming, and sometimes downright expensive. The good news? It’s also highly preventable. In this comprehensive guide, we’ll walk you through smart, real-world strategies to avoid getting locked out again—whether it’s your home, office, or car. These expert prevention tips come straight from the locksmith trenches, and they’re easy to apply, whether you’re forgetful, busy, or just tired of relying on emergency locksmiths. Understand Why Lockouts Happen in the First Place Before solving the problem, we need to understand it. Lockouts typically happen due to: Forgetting or misplacing keys Keys getting locked inside a car or home Doors that auto-lock Broken or worn-out keys Malfunctioning locks or key fobs Most of these are preventable with simple habits, upgrades, or tools. Let’s break them down one by one. Step 1: Create a Key Routine That You Can Stick To One of the most powerful prevention tools? Muscle memory. Create a ritual around your keys—something small and repeatable every time you leave your home, office, or car. For example: Always touch your keys before shutting the door Say “Phone, Wallet, Keys” as a mental checklist Place a reminder near the door (“Do you have your keys?” sign) These tiny behaviors train your brain to check for keys automatically—no effort required after a while. Step 2: Store a Spare Key (But Not Under the Mat!) A spare key is your best backup—but only if it’s stored smartly. Avoid outdated hiding spots like under the doormat, flowerpot, or inside the mailbox. These are the first places burglars check. Instead: Leave a spare with a trusted neighbor or friend Install a secure, weatherproof key lock box with a code Store it in your wallet or bag if it doesn’t interfere with routine And whatever you do, never label your key with your name or address. If it’s lost, your home could be at risk. More on this in our guide: Why You Should Never Hide a Spare Key Under the Mat Step 3: Duplicate and Distribute—Strategically Don’t rely on one key to rule your world. Instead, get professional duplicates made and keep them where you’re most likely to need them. Some smart storage ideas include: One in your car (but hidden securely) One in your gym bag or laptop case One at your workplace One with your dog walker, babysitter, or close family member Just make sure you trust whoever has access—and always update your key plan after roommates or tenants move out. Step 4: Go Keyless With Smart Locks If lockouts are a recurring issue, it might be time to ditch the keys altogether. Smart locks allow you to unlock doors using: Keypads (PIN codes) Smartphones Fingerprint access Bluetooth or Wi-Fi apps Some models even let you generate temporary codes for guests or service workers—so you don’t have to hide a key or hand out spares. Check out How to Upgrade to a Smart Lock Without Changing Your Door for a step-by-step breakdown of modern options that don’t require full door replacements. Step 5: Regularly Inspect Your Locks and Keys Sometimes, it’s not forgetfulness—it’s a failing lock or worn-out key that locks you out. Signs your key or lock may be due for a replacement: Your key feels loose or stiff in the lock You have to jiggle it to get it to work Your key is cracked, bent, or visibly worn You hear clicking, scraping, or feel resistance when turning A quick inspection once a month can catch small issues before they leave you stranded on the porch.

Step 6: Have a Go-To Locksmith on Speed Dial In case prevention fails (because life happens), don’t waste time Googling at 2AM when you're locked out. Instead: Research a local, licensed locksmith now Save their number in your phone as “Emergency Locksmith” Confirm they offer 24/7 lockout assistance Check their reviews, verify their licensing, and build a relationship with them before you need them. Our guide on How to Find a Licensed and Trustworthy Locksmith Near You walks you through exactly how. Step 7: Use a Smart Reminder or Tracker If you’re forgetful (hey, we’ve all been there), tech can help: Use a Tile or Apple AirTag on your keychain to track misplaced keys Set location-based reminders on your phone to check for keys before leaving Use apps like “Alarmy” to set a custom checklist for leaving the house These small hacks go a long way in building dependable habits. Bonus Tip: Re-Key After a Lockout (If Needed) If your lockout was caused by lost keys, it’s safer to rekey or replace the locks afterward. Why? Because if someone finds your keys and knows where you live, your home is no longer secure. Not sure what’s best? We break it down in Rekey vs Replace Locks: Which Is Better for New Homeowners? Final Thoughts: Lockouts Are Avoidable With the Right Systems A lockout doesn’t have to be part of your weekly routine. With a few simple changes—like key duplication, smart storage, tech upgrades, and routine maintenance—you can make sure that panic moment at the front door never happens again. It’s not about being perfect. It’s about being prepared. If you ever do get locked out again, don’t panic. Just call your trusted locksmith and take it as a reminder to refine your prevention system. You’ve got this—and your keys.
