Where Is The Best Place To Put A Deadbolt?

When it comes to home security, a high-quality lock is your first line of defense. While standard doorknob locks offer a basic level of protection, a deadbolt lock provides a much higher degree of security against forced entry. But simply having a deadbolt isn't enough; its placement is critical to its effectiveness.

Installing a deadbolt lock correctly can be the difference between a secure home and a vulnerable one. This guide will walk you through the most strategic locations for deadbolt locks, explain why their placement matters, and provide key considerations for installation. By the end, you'll have a clear understanding of how to maximize your home's security.

Why Deadbolt Placement is Crucial

A deadbolt lock is a simple but powerful mechanism. Unlike the spring-loaded latch in a typical doorknob, a deadbolt consists of a solid steel bolt that extends deep into the doorframe. It can't be forced back with a credit card or knife, making it highly resistant to break-in attempts.

However, its strength is only as good as its installation. If a deadbolt is placed too high or too low, or if the door and frame aren't properly reinforced, its security benefits can be significantly reduced. Correct placement ensures the lock engages fully and distributes force effectively, making it much harder for an intruder to kick the door in or pry it open.

The Best Places to Install a Deadbolt Lock

For optimal security, a deadbolt should be installed on every exterior door of your home. Intruders often check for the path of least resistance, so leaving one door unsecured can compromise the entire system.

1. Main Entry Doors (Front and Back)

This is the most obvious and important location. Your front and back doors are the primary entry points for both you and potential intruders. Every exterior door should be equipped with a quality single-cylinder deadbolt lock.

Ideal Positioning:
The deadbolt should be installed above the doorknob or handle set. The standard separation between the center of the deadbolt and the center of the doorknob is 5.5 to 6 inches. This spacing provides structural integrity and makes it difficult for an intruder to compromise both locks at once.

The doorknob itself should be positioned about 36 to 42 inches from the floor, which is a comfortable height for most adults. Following this, the deadbolt would be installed around 42 to 48 inches from the floor. This placement ensures the lock is easily accessible for everyday use while being positioned for maximum strength.

2. Side and Garage Entry Doors

Doors leading from the garage into your home or any side entry doors are often overlooked, but they are common targets for break-ins. These doors are typically less visible from the street, giving intruders more time and privacy to work on forcing a lock. It is essential to treat these entry points with the same level of security as your front door. Install a deadbolt lock on these doors using the same height and spacing guidelines.

3. French Doors and Patio Doors

French doors, while beautiful, can present a security challenge because they consist of two separate doors. For these, a double-cylinder deadbolt or a specialized vertical deadbolt system is often recommended.

· Double-Cylinder Deadbolt: This type requires a key on both the inside and outside. It prevents an intruder from breaking a glass pane and reaching in to unlock the door. However, be aware of safety concerns, as it can hinder a quick exit in an emergency. Check your local building codes, as some areas have restrictions on their use in residential properties.

· Vertical Deadbolt System: Some French doors are best secured with a multi-point locking system that includes a deadbolt that engages at the top and bottom of the door, providing greater stability.

Key Installation Considerations for a Deadbolt Lock

Proper installation is just as important as choosing the right location. Here are some critical factors to keep in mind:

Reinforce the Door and Frame

The strongest deadbolt in the world won't do much good if the doorframe is weak. Most forced entries occur because the doorframe splinters around the lock. To prevent this:

· Use a Heavy-Duty Strike Plate: The strike plate is the metal piece on the doorframe that the bolt extends into. Replace the standard, short-screwed plate with a heavy-duty one that is secured with 3-inch screws. These longer screws will go through the doorjamb and anchor into the wall stud, making the frame significantly more resistant to being kicked in.

· Check Your Door's Condition: Ensure your exterior doors are solid-core wood or metal-clad. Hollow-core doors are meant for interior use only and offer very little security.

Ensure Proper Alignment

The deadbolt must align perfectly with the strike plate and the hole in the doorframe. If it's misaligned, the bolt won't extend fully, compromising its strength. A properly installed deadbolt should lock and unlock smoothly without any need to push or pull on the door. Over time, a house can settle, causing misalignment. It’s a good idea to check your locks periodically and make adjustments as needed.

Choose a High-Quality Lock

Not all deadbolts are created equal. Look for locks that meet ANSI/BHMA (American National Standards Institute/Builders Hardware Manufacturers Association) standards.

· Grade 1: This is the highest security rating, typically used for commercial applications but an excellent choice for homes where maximum security is desired.

· Grade 2: This is a high-quality residential security rating and is sufficient for most homes.

· Grade 3: This provides basic residential security and is the minimum standard you should consider.

Bolster Your Home's Security

Properly installing a deadbolt lock is one of the most effective and affordable steps you can take to secure your home. By focusing on key entry points like your front, back, and garage doors and ensuring the locks are placed at the correct height, you create a formidable barrier against intruders. Remember to reinforce the doorframe and choose a high-quality, ANSI/BHMA-graded lock for the best results.

Taking the time to get the placement and installation right will provide peace of mind, knowing your home and family are well-protected.
