Deadbolt Vs. Door Knob Lock: Which Do You Need, And Do You Need Both?
When it comes to keeping your home safe, the kind of lock you choose matters. Many people assume a standard door knob lock is enough, while others swear by deadbolts. The truth is that both serve different purposes, and sometimes, using them together makes the most sense. To decide what’s right for your home, it helps to understand how each lock works, where it shines, and where it falls short.
Door Knob Lock Basics
A door knob lock is the most common lock you’ll see on front and interior doors. It’s built into the knob itself and is easy to use. These locks offer basic protection, but can often be picked or forced with enough effort. Their real strength is convenience, not maximum security. They’re good for keeping a door shut but aren’t the best option if you want a strong line of defense.
What’s Different About A Deadbolt?
Deadbolts are, inherently, much stronger. Instead of a small spring-loaded latch, a deadbolt uses a solid metal bolt that slides into the door frame. This makes it much harder to kick in or tamper with. Deadbolts are designed to withstand more force, which is why they’re considered the standard for real home security. If you want your door to resist break-ins, a deadbolt is almost always the way to go.
Everyday Use and Convenience
Door knob locks are quick to lock and unlock, which makes them more useful for daily life. You can shut the door behind you and it’s locked. Simple as that. Deadbolts, on the other hand, require an extra turn of a key or thumb latch. Some people find this inconvenient, but that extra step is what gives the deadbolt its strength. In everyday use, knob locks win for ease, but deadbolts win for security.
Do You Need Both Locks?
For most homes, the answer is yes. A door knob lock on its own is too easy to break through, while a deadbolt on its own, while strong, is probably not best as a sole line of defense. Together, they create multiple different layers of security. The knob lock provides practicality while the deadbolt brings true strength. Using both gives you a balance between ease and safety, which is often the best approach. You don’t want to be fumbling with a deadbolt in an emergency, for example.
When One Might Be Enough
There are times when one lock could be enough. For interior doors or low-risk areas, think a separate shed or trunk, a knob lock may be fine. On the other hand, if you’re talking about any door that offers entrance to a home, a deadbolt is the minimum you should have. The right choice depends on your surroundings and how much security you need (and how often you want to remember to set both locks).
Extra Tips for Stronger Security
Locks work best when paired with other measures. Reinforcing the door frame, using longer screws in strike plates, and choosing a solid door all add further protection. Even the best deadbolt won’t help much if the door itself is flimsy. For added peace of mind, consider smart locks or additional features like doorbell cameras or motion-activated lights. Good security is about the whole setup, not just the lock.

Both deadbolts and door knob locks have a place in home security. Knob locks offer convenience but little strength, while deadbolts provide the real barrier against forced entry. In most cases, using both gives you the best mix of safety and practicality. Think about your home, your habits, and your comfort level. The right combination of locks will bring both protection and peace of mind.
