Choosing a new lock for your home can feel overwhelming. With so many options, from traditional deadbolts to high-tech smart locks, how do you know which one is right for you? This guide will walk you through the differences between deadbolts, smart locks, and high-security options so you can confidently choose the best lock to keep your home and family safe.

Understanding the Basics: Types of Door Locks Explained
Before you can choose the right lock, it’s essential to understand the foundation of your home’s security. Each type of lock is designed for a specific purpose and offers a different level of protection. Learning the pros and cons of each will help you make an informed decision that fits your security needs and lifestyle.
Deadbolts: Your First Line of Defense
The deadbolt is the most critical component of your door’s security. Unlike the spring-loaded latch in a doorknob, a deadbolt cannot be pushed back without turning the key, making it highly resistant to forced entry. When choosing a deadbolt, you’ll encounter two main types: single-cylinder and double-cylinder. A single-cylinder deadbolt operates with a key from the outside and a thumb-turn on the inside, while a double-cylinder requires a key on both sides. While a double-cylinder can prevent a burglar from unlocking the door after breaking a nearby window, it can also pose a fire safety hazard. For most homes, a high-quality single-cylinder deadbolt with a hardened steel bolt that extends at least one inch is the minimum standard for reliable security on all exterior doors.
Smart Locks: Convenience Meets Modern Security
Smart locks bring modern convenience to home security. These electronic locks offer a range of features, including keypad entry with unique codes for family members, biometric fingerprint access, and remote control through a smartphone app. This is incredibly useful for families with kids, homeowners who have frequent guests, or rental property owners. You can grant temporary access to a dog walker or contractor without ever handing out a physical key. When considering a smart lock, be sure to look into its battery life, how it integrates with other smart home systems like Alexa or Google Home, and whether it has a physical key backup in case of a power outage or technical issue.
High-Security Locks: Maximum Protection Against Threats
For those seeking the highest level of protection, high-security locks are the ultimate choice. These locks are engineered to resist sophisticated methods of attack. They feature components like anti-pick, anti-drill, and anti-bump pins, which thwart common lock-picking and forced entry techniques. Constructed from hardened steel and other reinforced materials, they are physically stronger and more durable than standard locks. High-security locks are an excellent investment for anyone who wants maximum peace of mind and an uncompromising defense against potential intruders.
How to Choose: 3 Key Factors for Selecting the Right Lock
Selecting the perfect lock involves more than just picking a type. You need to match the hardware to your specific door, budget, and security goals. This simple checklist will help you consider the most important factors and make a choice you can feel confident about for years to come.
Decoding ANSI/BHMA Security Grades
Professional locksmiths and lock manufacturers use a standardized grading system from the American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) to rate the durability and security of locks. Understanding these grades is simple:
- Grade 1: This is the highest level of security available. It’s designed to withstand significant force and is tested for extensive use, making it suitable for both commercial properties and residential homes that require top-tier protection.
- Grade 2: Offering good security and durability, Grade 2 locks are a solid choice for most residential exterior doors. They meet the security needs of the average home and provide reliable protection.
- Grade 3: This is the most basic security rating. Grade 3 locks are best used for interior doors, such as bedrooms or closets, where high security is not a primary concern.
When to Replace vs. Rekey Your Locks
Sometimes you don’t need a brand-new lock. If your existing lock hardware is in good condition but you’ve lost a key or are concerned someone has a copy, rekeying is a cost-effective solution. A locksmith simply reconfigures the pins inside the lock cylinder to work with a new key. However, you should replace your locks entirely if they are old, damaged, rusted, or if you want to upgrade to a more secure model like a smart lock or a Grade 1 deadbolt. Moving into a new home is always the perfect time to replace the locks to ensure you are the only one with access.
Why Professional Lock Installation Matters
Even the best lock in the world is useless if it’s installed incorrectly. A poorly fitted lock can be easily bypassed, and improper installation can damage your door, frame, and the lock itself. A professional locksmith ensures that the lock is perfectly aligned, functions smoothly, and provides the maximum security it was designed for. Attempting a DIY installation can lead to vulnerabilities you may not even be aware of, giving you a false sense of security. For a flawless installation that guarantees your protection, it’s always best to trust an expert. Ready for a flawless installation? Call Locks R Us for expert service.

How much does it cost to have a new lock installed?
The cost varies depending on the type of lock you choose and the specifics of the installation. For a precise and transparent quote, it’s best to call a professional locksmith for an assessment.
Should I choose a smart lock or a traditional deadbolt?

How long does it take a locksmith to install a new lock?
For a standard residential door, a professional locksmith can typically install a new deadbolt or doorknob in under an hour. More complex installations may take longer.
