Home security begins at the door. Locks are the first and most important barrier between your home and the outside world. While many doors already come with a standard lock, upgrading to a high-quality deadbolt can significantly improve your safety. In this post, we’ll look at how deadbolts protect homes, what types to consider, and what to look for when upgrading.
Why Deadbolts Matter
A regular spring latch lock, often found on doorknobs, can be easily forced open with minimal effort. Deadbolts, on the other hand, provide a solid locking mechanism that cannot be retracted without turning the key or thumb turn. The bolt extends deep into the door frame, making it far more difficult to kick in or pry open.
Deadbolts work because they add real strength to the locking point. When the bolt fully enters a reinforced strike plate, the door becomes resistant to common break-in attempts like lock bumping or crowbar attacks. Even burglars who know how to pick locks tend to move on when they see a well-installed deadbolt.
We often recommend homeowners explore professional locksmith services in Ottawa when considering upgrades like these. A locksmith can assess whether your current door and frame can support a stronger lock or if reinforcement is needed.
Understanding the Types of Deadbolts
Different types of deadbolts serve different purposes. Knowing which one fits your door and security needs makes a big difference.
Single Cylinder Deadbolt
This is the most common type. It uses a key on the outside and a thumb turn on the inside. It’s simple and effective, ideal for most entry doors. The main limitation is that if your door has glass panels nearby, someone could break the glass and turn the knob from inside.
Double Cylinder Deadbolt
A double cylinder requires a key on both sides. It provides better security for doors with nearby glass or windows. However, it can slow down quick exits in an emergency, so it’s best used only on doors that are not main escape routes.
Smart Deadbolt
Modern smart locks combine deadbolt security with electronic access control. You can unlock them through your phone or keypad, and some can even alert you when someone enters. These are convenient, but you should still make sure they have a mechanical key backup in case the batteries fail.
Vertical Deadbolt
This style sits at the top of the door and resists prying or separation. It’s less common in residential use but can be valuable for back doors or basement entries that are more vulnerable to force.
Each type offers different strengths. The best choice depends on your home layout, door design, and personal habits.
Choosing the Right Grade and Material
Deadbolts are rated by ANSI (American National Standards Institute) into three grades: Grade 1, 2, and 3. Grade 1 is the highest and offers the most protection.
Grade 1 locks are usually found in commercial buildings, but homeowners who want maximum protection often choose them too. They can withstand more force and provide longer-lasting performance.
When it comes to materials, solid brass or steel bolts are ideal. Avoid hollow or lightweight materials, as they can bend or snap under force. Reinforced strike plates and long mounting screws are equally important. A deadbolt is only as strong as what it’s attached to.
Reinforcing the Door Frame
Many people focus on the lock itself but overlook the door frame. Even the best deadbolt cannot protect a weak frame. A strong kick can break the wood around the strike plate if it’s not reinforced.
To strengthen the frame, replace the standard short screws that come with most locks with 3-inch screws that anchor directly into the wall stud. This single upgrade can make it much harder for an intruder to force entry.
Installing a strike plate reinforcement kit can also provide a major improvement. These metal plates distribute the force of impact across a wider area. Adding a door jamb shield gives even more resistance against prying.
Proper Installation Techniques
Installing a deadbolt might look simple, but small errors can weaken security. The bolt should fully extend into the strike hole and align perfectly with the plate. If the hole is off even slightly, the lock may not latch properly, leaving a small gap that weakens the seal.
The hole in the frame must be deep enough for the bolt to extend fully. Some older frames have shallow recesses that stop the bolt from locking securely. Ensuring proper alignment and bolt extension is key to getting the full benefit of your upgrade.
We often find that homeowners who attempt installation on their own end up with a lock that looks right but doesn’t perform as it should. A professional locksmith can guarantee that everything fits tightly and works reliably.
Combining Deadbolts with Other Security Layers
Deadbolts are a major line of defense, but they work best when part of a larger security system. Adding a few other elements can greatly reduce your vulnerability.
Solid-core or metal-clad doors are essential. Lightweight hollow doors cannot hold up to force even with the strongest deadbolt. Reinforcing hinges with long screws or hinge bolts ensures the opposite side of the door is as secure as the lock side.
Adding a secondary latch like a chain or swing bar gives you a way to open the door slightly without unlocking it completely. This can be useful for checking on unexpected visitors.
A peephole or small camera near the entryway provides visibility before opening the door. The goal is to make it harder for intruders to find a weak spot while keeping everyday use convenient.
Common Mistakes to Avoid
Upgrading locks is simple, but small mistakes can compromise the effort.
One mistake is installing a good deadbolt on a weak door. The strength of the lock means little if the door flexes easily. Another is forgetting to reinforce the frame. Intruders rarely pick locks when they can just kick the door near the latch.
Some people choose decorative locks that look solid but use low-grade internal parts. It’s worth checking the packaging or asking a locksmith about the ANSI rating before buying.
Finally, avoid overcomplicating your setup. For example, using double cylinder deadbolts on main exits can be risky in case of fire. Function and safety must stay balanced.
Maintenance Tips for Long-Term Security
Like any mechanical system, locks wear down over time. Dust, temperature changes, and frequent use can cause parts to stick or loosen. Simple maintenance keeps them working smoothly.
Every few months, check that the screws in both the lock and strike plate are tight. A small amount of graphite lubricant keeps the keyway operating without sticking. Avoid using oil-based lubricants, as they attract dirt.
Test your lock occasionally by locking and unlocking it several times. If it feels stiff, the alignment might have shifted. Adjusting the strike plate or tightening the screws can prevent long-term wear.
Seasonal changes can also affect doors, especially in Ottawa’s climate. Wood expands and contracts with temperature and humidity, which can affect how the bolt fits. A professional check once a year can ensure everything stays aligned.
The Role of Professional Locksmiths
Even when a deadbolt looks like a simple device, it’s still part of a larger security system. Professional locksmiths do more than install locks. They assess the structure of your door, check for weak points, and match hardware to your specific needs.
If you’re unsure where to start, you can explore trusted locksmith services in Ottawa to learn what options best fit your home. Many homeowners underestimate how small details—like screw placement or frame alignment—affect safety.
A locksmith can also rekey locks, install smart systems, or combine mechanical and digital access for better control. They ensure that new locks integrate well with your existing keys or security habits.

Extra Insight: The Hidden Value of Door Hardware
Most people focus on the lock cylinder and forget the surrounding hardware. Door handles, strike plates, hinges, and screws all influence how secure the lock actually is. For example, a deadbolt installed on a thin metal plate can bend under pressure.
Upgrading to heavy-duty plates and solid handles enhances both strength and durability. High-quality hardware also resists corrosion, which is important in cold and humid climates like Ottawa’s.
Paying attention to these small components prevents gradual loosening that can make locks misalign over time. The overall feel of the door should be firm and solid, not wobbly or hollow.
Energy and Noise Benefits
A properly sealed and aligned door with a strong deadbolt can also help improve insulation. Air leaks often occur around doors that don’t close tightly. A secure fit reduces drafts, which saves energy during winter and summer.
The same seal helps block outdoor noise, providing a quieter living environment. While this is a secondary benefit, it shows how security improvements often bring comfort and efficiency along with protection.
Balancing Security with Accessibility
Good security should never come at the cost of convenience. A deadbolt that’s too hard to operate may not get used properly. If you have elderly family members or children at home, choose hardware that feels comfortable and smooth to turn.
Smart locks can be a good option for accessibility since they allow keyless entry, but they should always include manual override features. Combining digital access with traditional mechanical reliability gives you the best of both worlds.
