Comparing Deadbolt vs Spring Latch Locks: What Homeowners Need to Know

When it comes to home security, the type of lock you choose can make all the difference. While there are countless options available on the market today, two of the most commonly used types are deadbolt and spring latch locks. At first glance, they might seem similar—they both keep doors closed and provide basic protection—but a closer look reveals important differences in how they work, how secure they are, and where they’re best used.

Understanding the distinction between deadbolts and spring latches is essential for homeowners who want to protect their property effectively. In this comprehensive guide, we’ll break down how each lock functions, examine their pros and cons, and help you decide which is the best fit for your home’s entry points.

What Are Spring Latch Locks?

Spring latch locks, also known as slip bolt locks or latch bolts, are the most common type of lock found on residential doors—particularly interior doors or exterior knobs with built-in latching mechanisms. The key feature of a spring latch lock is its spring-loaded bolt, which retracts when you turn the knob or handle and automatically springs back into place when the door is closed.

These locks are incredibly convenient and easy to use. Once the door is shut, the latch clicks into place, requiring only the turn of a knob (or a key from the outside) to open it again. This self-latching mechanism is one reason why spring latch locks are so common.

However, their convenience comes at a cost: security. Because of their spring mechanism, these locks can be vulnerable to being “loided” (slipped open with a credit card or similar object), especially if installed without reinforcement. While many models include added features like anti-pick pins or reinforced plates, spring latches are generally considered a lighter-duty option in the world of home security.

What Are Deadbolt Locks?

A deadbolt lock is a manually operated locking mechanism that uses a solid metal bolt which must be physically extended and retracted using a key or thumb turn. Unlike spring latches, deadbolts do not rely on a spring or automatic retraction—they stay locked or unlocked until manually changed by the user.

Deadbolts are typically installed above a knob or lever and offer significantly greater resistance to forced entry. When locked, the bolt extends deep into the door frame, making it much more difficult to kick in or manipulate with a tool. Deadbolts come in several varieties, including:

• Single cylinder deadbolts, which require a key on the outside and a thumb turn on the inside
• Double cylinder deadbolts, which require a key on both sides
• Lockable thumb turn deadbolts, offering a blend of single and double cylinder functionality

Deadbolts are considered the gold standard for exterior door security, and are often recommended by security professionals and law enforcement.

Security Comparison: Deadbolt vs Spring Latch

When evaluating deadbolt and spring latch locks from a security standpoint, the difference is clear. Deadbolts provide superior resistance against both forced entry and lock manipulation. Because they lack a spring-loaded mechanism, they cannot be easily retracted with a credit card or by jiggling the handle—common methods used by intruders to defeat spring latches.

Spring latch locks are relatively easy to bypass unless reinforced with additional hardware or used in combination with a deadbolt. Their primary function is convenience, not heavy-duty protection.

That said, spring latches can still serve a role in home security. When paired with a deadbolt on an exterior door, they can provide a two-step entry system. For interior doors—like bedrooms or home offices—a spring latch may be sufficient, especially when privacy, not high security, is the goal.

Use Case Scenarios: Where Each Lock Makes Sense

Deadbolt locks are the right choice for:

• Front and back exterior doors
• Garage-to-home entries
• Any door leading into the home from outside
• Side or basement entrances
• Rental properties or multi-tenant buildings
• Homes in high-crime areas

Spring latch locks are appropriate for:

• Interior bedroom or bathroom doors
• Closet or pantry doors
• Secondary locks on exterior doors (paired with a deadbolt)
• Areas where ease of use is more important than maximum security
• Light-duty entry points, such as guest houses or sheds (with additional security measures)

By understanding where each type of lock is most effective, homeowners can create a layered security strategy that balances ease of use with strong protection.

Installation Differences

Both types of locks can be installed as DIY projects, but the complexity varies.

Spring latch locks are generally easier to install, especially if you’re replacing an existing knob or handle. Most modern doors come pre-drilled for this type of lock, and standard kits can be installed with basic tools.

Deadbolts may require additional drilling and precise alignment, especially if your door doesn't already have a deadbolt bore. For maximum effectiveness, the strike plate for a deadbolt should be anchored into the wall studs with 3-inch screws. While many handy homeowners can tackle this job themselves, others may prefer to hire a professional locksmith to ensure the deadbolt is installed correctly.

Durability and Long-Term Performance

Deadbolts tend to be more durable over time than spring latch locks. Because they’re less dependent on moving springs and internal mechanisms, there’s less chance of wear-and-tear impacting functionality. High-quality deadbolts also feature solid brass or steel components that resist corrosion and physical damage.

Spring latches, particularly cheaper models, can wear down faster. The internal spring mechanism may weaken, causing the latch to stick or fail to close properly. For homeowners in humid or coastal areas, spring latches may also be more prone to rust and corrosion.

Cost Comparison

Spring latch locks are typically more affordable, with many models available for under $25. They’re a budget-friendly option, especially for interior doors or temporary setups.

Deadbolts cost more, ranging from $30 to over $100 depending on the model and features. High-security deadbolts or smart deadbolt locks may carry a higher price tag but offer far greater value in long-term protection and peace of mind.

It’s worth noting that in terms of home security investment, a high-quality deadbolt is one of the most cost-effective upgrades you can make.

Smart Lock Compatibility

For homeowners interested in smart home integration, both lock types are available in smart formats. However, most smart locks use a deadbolt mechanism as the primary security feature. These include app-based control, keyless entry, biometric scanning, and remote locking/unlocking.

Some smart spring latch locks are available, often for interior applications, but they generally do not offer the same security benefits as smart deadbolts. When it comes to smart home security, deadbolts remain the preferred standard.

Choosing between deadbolt and spring latch locks comes down to a question of purpose. For any exterior door where security is a priority, a deadbolt is an absolute must. It offers far superior protection against forced entry, tampering, and key duplication. Spring latch locks, while useful in the right situations, should never be your sole line of defense on entry doors.

That said, spring latches do offer convenience and are appropriate for low-security areas inside the home. For the best results, consider using both together—combining the quick access of a spring latch with the powerful protection of a deadbolt.
