Best Locks & Latches for US Homes: Where to Buy, What to Choose, and How to Install

Why locks & latches still matter in a smart-home world

You might think locks are boring until you forget your keys at 10 p.m. or notice a loose latch on a garden gate after a storm. Locks and latches are the quiet, physical backbone of home security — they protect your family, preserve privacy, and keep your stuff where it belongs. Even with the rise of smart home tech, a well-chosen deadbolt, a solid latch, or a reliable smart lock often makes the difference between peace of mind and an afternoon of anxiety. Let’s walk through what matters when you buy locks and latches, where to shop, and how to make the most of your purchase.

Types of locks and when to use them

Not all locks are created equal, and different doors and use-cases call for different solutions. Are you securing a front door that sees heavy traffic, a gate that gets rained on, or a bedroom that needs a simple privacy latch? Understanding basic lock types — deadbolts, smart locks, mortise locks, padlocks, and latches — helps you pick the right product and avoid expensive returns or risky installations.

Deadbolts: the standard for front doors

Deadbolts are the first line of defense for exterior doors. A single-cylinder deadbolt with a 1 1/8-inch faceplate and a 2 3/8-inch to 2 3/4-inch backset is what you usually see on modern homes. Go for an ANSI Grade 1 or 2 deadbolt if you want higher resistance to forced entry. They work mechanically, so even if power or Wi‑Fi goes out, they still protect your door — which is a comforting thought.

Smart locks and keyless entry: convenience with caveats

Keyless smart locks add convenience: PIN codes, smartphone access, and temporary guest keys. Models vary — some connect directly via Bluetooth, others use Wi‑Fi, Z‑Wave, or Zigbee to integrate into a smart-home system. Consider battery life (often measured in months), the lock’s Wi‑Fi range in feet, and whether the smart lock works with your door’s standard 1 3/4-inch thickness. Smart locks are great for rentals and busy households, but you should pair them with a reliable mechanical deadbolt or backed-up power solution.

Mortise locks and lever handles: durable choices for heavy use

Mortise locks sit inside a pocket cut into the door and are commonly used in multi-family buildings or older homes. They’re built for heavy duty and last longer under frequent use. If you have an interior door that needs robust commercial-grade hardware — like an office or workshop — mortise locks and ANSI-rated levers are worth the extra cost.

Latches, hasps, and gate hardware: the small parts that matter

Don’t underestimate latches — they can be the weak link. Gate latches, shed hasps, and sliding door bolts need to be weather-resistant and sturdy. Look for stainless steel or brass finishes if your latch will face rain, salt air, or winter freeze. A garden gate latch rated for outdoor use and lined up with a sturdy post makes a big difference in security and longevity.

Top places to buy locks & latches in the US

Where you buy matters: some retailers focus on budget-friendly options, others on pro-grade hardware or expert installation. Online marketplaces give huge selection, while local hardware stores offer personal advice and easier returns. Below are some of the most trusted options across the US, starting with Walmart — a big name that shows up in many shoppers’ searches.

Walmart: value and smart-lock selection

Walmart is a go-to for homeowners looking for affordable locks, replacement latches, and entry-level smart locks. You’ll find keyless deadbolts, keypad locks, and brands that offer smartphone control without a hefty price tag. Walmart’s in-store pickup and nationwide footprint make it easy to grab a replacement latch the same day. If you’re buying a smart lock, read user reviews to confirm compatibility with your door’s thickness and your smartphone’s operating system.

Home Depot: pro-grade hardware and installation help

Home Depot stands out for its wide selection of residential and commercial-grade locks, plus options for in-store key cutting and professional installation. You can compare ANSI Grade 1, 2, and 3 locks, pick up the right strike plate, and get drill templates to match common door preparations. Home Depot also stocks weatherproof gate latches and deadbolts rated for exterior use, making it a strong choice for DIYers and contractors alike.

Lowe’s: homeowners’ favorite for variety and service

Lowe’s carries a robust range of smart locks, deadbolts, and decorative hardware. Many stores offer hands-on displays so you can feel the lever and test the latch action. Lowe’s typically matches competitive prices and provides installation services if you prefer a pro to handle the drilling and alignment — especially helpful on heavy doors where precision matters.

Ace Hardware and local hardware stores: neighborhood knowledge

Ace and other independent hardware shops are great when you want personalized advice. These stores often stock heavy-duty latches, specialty lock cylinders, and vintage-style hardware for older homes. Local pros can recommend the best latch type for a 36‑inch gate or help you source a replacement strike plate for a historic front door.

Amazon and online marketplaces: massive choice, buyer beware

Online marketplaces like Amazon offer nearly every brand and price point, from budget keypad locks to premium smart models. The advantage is variety and fast shipping, but the trade-off is sifting through mixed reviews and counterfeit risks. Always check seller ratings, warranty details, and whether the product ships with screws and templates for doors that are 1 3/4 inches thick — those little extras save you a trip back to the hardware store.

How to choose the right lock for your door

Choosing a lock is a bit like choosing shoes: fit, purpose, and durability matter most. Ask yourself whether the lock will face heavy use, weather exposure, or the need for smart features. Measure your door thickness and backset in inches, check the existing borehole size (usually 2 1/8 inches), and decide on the level of security you need. For front doors, aim for at least an ANSI Grade 2 deadbolt; for high-risk areas pick Grade 1. Don’t forget aesthetics — a matching finish on handles and hinges ties the look together.

Installation tips for DIYers

Installing a lock can be a satisfying DIY job if you prepare. Use the included template, keep the door steady, and pre-drill holes to prevent splitting. For deadbolts, ensure the strike plate lines up flush with the jamb — shim it with a piece of wood if needed to get the deadbolt to fully extend. If installing a smart lock, test battery fit and smart pairing before you screw everything tight. And always test the lock several times with the door open to make sure the latch retracts smoothly without binding.

Maintenance and longevity: keep your locks secure

Locks aren’t “fit it and forget it.” Regular maintenance extends life and prevents frustrating jams. Lubricate locking mechanisms with graphite or a dry lubricant once a year, tighten screws that may loosen over time, and replace weatherstripping if water gets into the latch area. For smart locks, swap batteries every 6 to 12 months depending on usage and keep firmware updated to benefit from security patches and feature improvements.

Budget options vs premium picks: what to expect

On a tight budget, you can get a functional deadbolt or basic keypad lock that improves security instantly. Entry-level models are great for rental properties or secondary doors. If you’ve got more to spend, premium locks offer better materials (hardened steel, brass), longer warranties, and advanced smart features like biometric entry, built-in Wi‑Fi, and integrations with virtual assistants. Think of budget locks as sturdy sneakers and premium locks as a well-crafted pair built to last — both will get you where you need to go, but one will feel nicer and hold up better over time.

Final checklist before buying locks & latches

Before you hit “buy,” run through this checklist: measure door thickness in inches, confirm borehole and backset sizes, decide on ANSI grade, check finish compatibility with other hardware, read reviews from buyers who tested the lock in real conditions, and verify that mounting hardware and templates are included. If you’re buying a smart lock, ensure compatibility with your phone, hub, or voice assistant and learn how many months of battery life to expect under normal use.

Conclusion

Choosing the right locks and latches is a balance of security, convenience, and budget. From Walmart’s value-focused selection to Home Depot’s pro-grade options, and from local hardware stores’ personalized help to Amazon’s massive variety, there’s a solution for every door and every homeowner. Measure carefully, pick a trusted brand when possible, and don’t skimp on installation. A good lock is more than a purchase — it’s peace of mind measured in inches and pounds, something you’ll appreciate each time the door clicks shut.
