You decided to get a smart lock. Good move. But when you open Amazon, there are hundreds of options.
Different brands. Different features. Different prices. Suddenly, you feel more confused than when you started.
I’ve been there. This guide is for you. No jargon. No tech hype. Just what to actually look for when you’re buying your first smart lock.

Step 1: Ask Yourself One Question First
Before you look at any brands, ask: Do I want to keep my existing lock or replace it entirely?
This one decision narrows your options by half.
Retrofit locks (like August) attach over your existing deadbolt. You keep your keys. Installation takes 10-20 minutes. Great for renters or anyone who doesn’t want to commit to a new lock.
Full-replacement locks (like Schlage Encode and Yale Assure) replace the entire deadbolt. More features. Cleaner look. Takes 30-45 minutes to install. Better for homeowners ready to make the switch.
One Reddit user summarized it simply:
“Just put the smart lock where the deadbolt is. If someone can get through a deadbolt, that matters more than whether it’s smart or not.”
Step 2: Check Your Door First

This step sounds obvious. But it’s the #1 thing beginners skip.
Before buying anything, check these:
- Door thickness. Most smart locks work with doors 1.375″ to 2″ thick. Measure yours.
- Backset distance. That’s the distance from the door edge to the center of your deadbolt hole. Standard is 2-3/8″ or 2-3/4″.
- Single borehole or two? Some doors have a separate handle and deadbolt. Others have one combined hole. Know yours.
- Door alignment. Close your door. Does it catch or drag? If your door doesn’t close smoothly now, a smart lock won’t fix it.
One locksmith noted:
“Complicated electronics, parts that require excellent door alignment, which is incredibly rare, and cheap manufacturing make them possibly the most returned item in home security.”
If your door already has issues, fix the door first.
Step 3: Understand the Security Ratings

You keep seeing “ANSI Grade 1” and “BHMA certified.” Here’s what that actually means.
The ANSI/BHMA grading system tests locks for security, durability, and finish. There are three grades:
- Grade 1: Highest residential rating. Built for commercial use. Best resistance to forced entry.
- Grade 2: Standard for most residential smart locks. Good security for everyday use.
- Grade 3: Minimum acceptable. Fine for interior doors. Not ideal for your front door.
The ANSI/BHMA standard requires locks to pass operational, cycle, strength, security, material, and finish tests. A Grade 1 lock has been through more rigorous testing than Grade 3.
One Reddit user recommended:
“Schlage makes a few keypad deadbolts that are ANSI Grade 2, which will resist forcible entry attacks reliably better than most generic brands.”
If security is your priority, aim for ANSI Grade 1 or Grade 2.
Step 4: Decide How You Want to Unlock
Smart locks offer several ways to get in. You don’t need all of them. Pick what works for your household.
- App + Bluetooth. Your phone becomes your key. Walk up, lock unlocks. No fumbling. Most reliable when you’re at home.
- Keypad / PIN code. Great for kids, guests, and dog walkers. No phone needed. You can set temporary codes.
- Fingerprint. Fastest unlock method. Touch the sensor, you’re in. Popular in the 2026 smart lock market.
- Apple Home Key / Google Wallet. Tap your phone or watch to unlock. Super convenient if you’re already in that ecosystem.
- Physical key. Still included on most locks. Good backup for emergencies.
For beginners, a keypad + app combination covers most situations. Add a fingerprint if you want maximum convenience.
Step 5: Match Your Smart Home Ecosystem
This matters more than most buyers realize.
Not all smart locks work with all platforms. A lock that works perfectly with Apple Home might be complicated with Google Home. Before falling in love with a lock, check:
- Apple Home. Best options: Schlage Encode Plus, Yale Assure Lock 2, Level Lock Pro.
- Google Home. Most Wi-Fi locks work. Yale Assure 2 with Wi-Fi module is a solid pick.
- Amazon Alexa. August, Schlage Encode, most locks with Wi-Fi modules.
- Matter protocol. Newer standard. If you want your lock working across platforms in 5 years, Matter matters. Kwikset Aura Reach and Aqara U200 are good Matter options.
CNET’s buying guide advises:
“Always investigate third-party compatibility and if the smart lock works with what you prefer.”
If you use multiple assistants, look for Matter support. It future-proofs your purchase.
Step 6: Set Your Budget
Smart locks range from $50 to $400+. Here’s what you get at each level:
- $50-$100: Basic keypad locks. Wyze Lock Bolt is a solid pick here. No Wi-Fi, but a reliable fingerprint and keypad.
- $100-$200: Most popular range. August WiFi, Yale Assure Lock 2, Kwikset Aura. Good features, solid security.
- $200-$300: Premium territory. Schlage Encode Plus (Apple Home Key), Ultraloq Bolt Fingerprint (best fingerprint tech). Top-tier build quality.
- $300+: Advanced features. Level Lock Pro (invisible design), Eufy FamiLock S3 Max (lock + doorbell combo). Niche buyers only.
For most beginners, the $100-$200 range hits the sweet spot. SafeHome.org notes that brands like August and Schlage offer options from $50 to $300, so there’s something for every budget.
Step 7: Look for These Security Features
Not all smart locks are equal when it comes to security. Look for:
- AES-256 encryption. Security.org recommends choosing locks that use AES-256-bit encryption — the current industry standard.
- Two-factor authentication. Extra layer for app logins. Turn it on if your lock supports it.
- Auto-lock. Door locks automatically after a set time. Never forget to lock again.
- Activity logs. See who unlocked the door and when. Great for families and rental property owners.
- ANSI/BHMA certification. Third-party tested security. Look for it on the box.
Security experts recommend looking for strong encryption and two-factor authentication as baseline requirements for any smart lock.
Common Beginner Mistakes to Avoid
Learn from others’ mistakes so you don’t make them yourself.
1. Skipping door prep. A smart lock on a misaligned door is a headache. Test your door first.
2. Ignoring compatibility. A lock might be perfect, but it might not work with your phone or smart home hub. Check before buying.
3. Going too cheap. smart locks from unknown brands often have poor encryption and no security updates. Stick to established names.
4. Not planning for power outages. Battery dies, you’re locked out. Keep a physical key nearby. Yes, even on a smart lock.
5. Forgetting about sun exposure. One Reddit user in Arizona noted:
“Mine faces west and gets a ton of direct sunlight. Make sure your lock is rated for outdoor use if it gets sun.”
6. Overbuying features. You probably don’t need facial recognition, voice unlock, fingerprint, and NFC all in one lock. Pick what you’ll actually use.
The Bottom Line
Choosing your first smart lock doesn’t have to be overwhelming. Work through these steps in order:
- Decide: retrofit or full replacement?
- Check your door measurements
- Prioritize security with ANSI Grade 1 or 2
- Pick your unlock methods
- Match your smart home ecosystem
- Set a realistic budget
- Verify the security features
The best smart lock is the one that fits your door, your ecosystem, and your budget. Not the most expensive one. Not the one with the most features. The one you’ll actually use every day.
If you’re still unsure, start with the Yale Assure Lock 2. It works with all major platforms, has excellent build quality, and sits in the mid-range price bracket. A solid choice for most beginners.
