When it comes to home security, one of the most important factors to consider is the type of lock you use on your doors. A deadbolt lock is a popular choice for homeowners, offering a higher level of security than a standard lock. In this article, we will cover everything you need to know about deadbolt lock installation, including the benefits of using a deadbolt lock, different types of deadbolt locks, and how to install it yourself or with the help of a professional locksmith.
Deadbolt Lock Benefits
Deadbolt locks are a popular choice for homeowners due to their many benefits. They are more secure than standard locks, with a locking mechanism that extends into the door frame to provide extra protection against forced entry. Additionally, they are available in a variety of styles and finishes to match any home decor.
Another benefit of deadbolt locks is that they can be upgraded to include smart lock features. With a smart deadbolt installation, you can control your lock remotely through a mobile app or voice assistant, monitor who comes and goes from your home, and receive notifications when someone enters or exits.
Deadbolt Lock Standards
Deadbolt lock standards are important because they ensure that the locks are strong enough to resist forced entry attempts. ANSI and BHMA establish deadbolt lock standards based on the lock’s strength and durability. Deadbolts are graded on a scale of 1 to 3, with Grade 1 being the strongest and most durable. Grade 1 deadbolts are designed for commercial use, while Grade 2 and 3 deadbolts are suitable for residential use.
To achieve a Grade 1 rating, a deadbolt lock must be able to withstand 10 hammer blows, 250,000 cycles, and 5 strikes with a blunt object. Grade 2 locks are tested for 5 hammer blows, 150,000 cycles, and 3 strikes with a blunt object. Finally, Grade 3 deadbolts are tested for 2 hammer blows, 75,000 cycles, and 1 strike with a blunt object.
The Most Common Deadbolt Types
Before you install a deadbolt, it’s important to understand the different types that are available.
Single Cylinder Deadbolt

This is the most common type of deadbolt found in homes. It has a keyhole on one side and a thumb turn on the other. The keyhole allows you to lock or unlock the deadbolt from the outside, while the thumb turn is used to lock or unlock the deadbolt from the inside.
Double Cylinder Deadbolt

This type of deadbolt is similar to a single cylinder deadbolt but requires a key to unlock or lock the deadbolt from both inside and outside. It provides increased security, but it can also be a fire hazard if not used correctly. In an emergency, you’ll need to locate the key to unlock the deadbolt from the inside.
Lockable Thumbturn Deadbolt

This particular style of deadbolt may be locked using only one’s thumb and does not require the use of a key. It provides an increased level of convenience as well as security.
Jimmy Proof Deadbolt

A Jimmy Proof, or in other words, auxiliary deadbolt, is a surface-mounted deadbolt that is often used on double doors. Locksmiths install it on the door’s surface rather than insert it into the door, making the deadbolt installation process relatively easier. Technicians often use these deadbolts on doors that cannot accommodate a traditional deadbolt. Jimmy Proof deadbolts are available in single-cylinder, double-cylinder, and simple thumbturn deadbolts from one side.
Mortise Deadbolt

A mortise deadbolt is a type of deadbolt that locksmiths install inside the door. It requires a mortise cutout in the door for installation. Mortise deadbolts are often used on high-security doors because they provide greater strength and security than other types of deadbolts.
Smart Deadbolt

A smart deadbolt is a type of deadbolt that you can control by using a smartphone or a voice assistant. These deadbolts often come with additional features like remote access, auto-locking, and guest access codes.
Keypad Deadbolt

A keypad deadbolt is a type of smart deadbolt that has a keypad instead of a keyhole. You can enter a code on the keypad to lock or unlock the deadbolt. These deadbolts are often used in rental properties or homes with multiple occupants.
Interconnected Deadbolts

These types of deadbolts are typically used on commercial or multi-unit residential buildings. They have a single lock mechanism that controls both the deadbolt and the latch. They are typically more expensive and difficult to install than other types of deadbolts.

How to Install a Deadbolt Lock
Before you begin the deadbolt installation process, you will need to gather the necessary tools and materials. You will need a drill, a hole saw, a screwdriver, a chisel, a hammer, a tape measure, a pencil, a level, a deadbolt lockset, and screws.
Step 1: Measure and Mark the Placement of the Deadbolt Lock
The first step is to measure and mark the placement of the deadbolt lock. Start by measuring the height of the lock and marking it on the door. Use the level to ensure that the mark is straight. Then, use the template that came with the lock to mark the placement of the lock cylinder and the bolt.
Step 2: Drill the Holes
Next, drill the holes for the lock cylinder and the bolt using the hole saw. Be sure to drill straight and follow the markings on the template. Then, use the drill to create a hole for the latch on the door frame.
Step 3: Chisel Out the Mortise
Use the chisel and hammer to create a mortise for the latch plate on the door frame. Be sure to chisel the mortise deep enough to allow the latch plate to sit flush with the surface of the frame.
Step 4: Install the Deadbolt Lockset
Insert the deadbolt lockset into the hole for the lock cylinder on the door. Use the screws to attach the lockset to the door. Then, insert the bolt into the hole for the bolt and attach the strike plate to the door frame using screws.
Step 5: Test the Lock
Test the lock to make sure it is functioning properly. Turn the key to lock and unlock the deadbolt. Make sure the latch is fully extending and retracting into the mortise on the frame.
Step 6: Finish the Installation
Finally, finish the installation by attaching the trim plates and other accessories that came with the lockset. Follow the manufacturer’s instructions carefully to ensure proper installation.
