The right lock for your home will keep your property and loved ones safe. Modern residential locks come in various styles, finishes, and security levels and incorporate features once reserved for commercial use. We’ll provide tips for choosing the best lock for your home, detailing factors such as security grades, types of locks, and advanced features.
Understanding Lock Security Grades
Before choosing a lock, you need to understand the security grades assigned to different types. These grades give valuable information about a lock’s durability and resistance to forced entry.
ANSI Grading System
The American National Standards Institute (ANSI) grades locks based on their security level. The ANSI grading system uses three levels:
- Grade 1: Highest security level
- Grade 2: Intermediate security level
- Grade 3: Basic security level
Grade 1 locks offer the most robust security features and are typically used in commercial settings or high-security residential applications. Grade 2 locks balance security and affordability for most homes, while Grade 3 locks are basic models suitable for interior doors or areas with minimal security concerns.
When choosing a lock, get the most security you can afford. Manufacturers don’t always list lockset grades, so you may have to ask. Be skeptical of a lock that boasts Grade 1 “features”—just because it has one or two high-security features doesn’t mean it has earned the ANSI grade.
Types of Residential Locks
Several types of locks are available for residential use, each with its own advantages and security features. Understanding these options will help you make an informed decision about your home.
Key-in-Knob Locks
Key-in-knob locks, also called tubular locks, are the most basic type of residential lock. They operate with a key on the outside and a thumb turn or button on the inside. Mass-market tubular locks are usually made of stamped brass. Higher-end locks use heavier forged brass with a more solid feel and a harder-wearing finish. While convenient, these locks don’t offer much security on their own and are typically paired with a deadbolt for added protection.
Deadbolts
Deadbolts are a cornerstone of door security. They come in two main types:
- Single cylinder deadbolts: Unlock with a key on the outside and a thumbturn on the inside. This is the most common type of deadbolt.
- Double cylinder deadbolts: Require a key on both sides to provide extra security. They’re great on doors with glass panels or sidelights since an intruder can’t smash the glass and open the door.
Double cylinder deadbolts can slow escape during a fire. One solution, required in some places by code, is a double-cylinder deadbolt with a “captive” feature. This feature prevents you from removing the interior key when the door is locked from the inside.
Entry Handlesets
Entry handlesets combine a tubular lockset and deadbolt in one matching set. They typically feature a thumb latch instead of a round knob to retract the lower spring-loaded mechanism. Most handlesets only have a keyed deadbolt, but some offer the option of a keyed thumb latch for added security.
Mortise Locks
Mortise locks are the strongest residential locksets available. They feature a spring-loaded latching mechanism and deadbolt in a single rectangular housing. The lock is recessed, or “mortised,” into the edge of the door. While they’re expensive and require professional installation, mortise locks offer superior security and are available in various styles.
Electronic Locks
Electronic locks offer keyless entry options using access codes and smart technology. You can change the codes as often as necessary and give temporary ones to painters, babysitters, and house cleaners. They run on batteries and many electronic locks still include an old-fashioned key option as a backup.
Factors To Consider When Selecting a Lock
Choosing the right lock for your home involves considering several factors beyond security.
Door Type and Material
Check that your chosen lock is compatible with your door’s specifications to avoid installation issues or compromised security. Here are some factors to consider:
- Door thickness
- Material (wood, metal, fiberglass)
- Existing hardware and cutouts
Budget Constraints
Lock prices vary widely, from basic models to high-end smart locks. Set a realistic budget that balances security needs with cost. Remember that investing in a quality lock can give you long-term peace of mind and even lower your insurance premiums.
Aesthetic Preferences
Locks are available in various finishes and styles to complement your home’s decor. Here are some popular finish options:
- Brass
- Satin nickel
- Antique bronze
- Powder-coated finishes
Installation Requirements
Consider your skill level and available tools when selecting a lock. Complex systems like mortise locks typically require professional installation for proper function and security.
Key Technologies and Innovations
The field of lock technology continues to evolve, offering homeowners new options for securing their properties. These options give flexibility and enhanced control over who can access your home.
Traditional Keys vs. Electronic Fobs
While traditional keys remain common, electronic fobs are gaining popularity. Fobs offer keyless entry, and you can easily deactivate them if they’re lost or stolen. Some systems allow for both key and fob access, providing flexibility and backup options.
Biometric Access Systems
Biometric locks use unique physical characteristics, such as fingerprints or retinal scans, for access. These systems offer high security and convenience, eliminating the need to carry keys or remember codes.
Keyless Entry Options
Keyless entry systems include:
- Keypads with programmable codes
- Bluetooth-enabled locks that work with smartphones
- Wi-Fi-connected locks for remote access and monitoring
Choosing the Right Lock for Specific Areas
Different areas of your home may require different types of locks based on their security needs and usage patterns. Consider these recommendations for various entry points.
Front Door Security
The front door is your home’s primary entry point and requires the highest level of security. Recommendations include:
- Grade 1 deadbolt
- Smart lock or electronic deadbolt for added convenience
- Peephole or video doorbell for visitor identification
Back Door and Patio Door Locks
Back doors and patio doors are common targets for intruders. Secure these areas with:
- High-quality deadbolts
- Sliding door locks or security bars for patio doors
- Reinforced strike plates and longer screws
Interior Door Locks
Interior doors typically require less security than exterior doors. Options include:
- Privacy locks for bedrooms and bathrooms
- Passage locks for closets and other areas that don’t require security
- Keyed locks for home offices or storage rooms with valuable items
