Every “best budget smart lock” roundup has at least one pick over $250. You’ve noticed. The Wirecutter top pick is $299. CNET’s “budget” list includes a $233 lock. The Verge recommends one at $349.
Here’s the deal: every lock in this article is under $200. Not “$200 before the hub you also need.” Not “under $200 during a sale that ended in November.” Under $200, right now, total cost for a working smart lock on your door.
And unlike every other list, we’ll tell you whether it actually fits your door before you order it.
What You Actually Lose Under $200 (and What You Don’t)
A $150 smart lock in 2026 does about 95% of what a $300 one does.
What you give up: fancier metal finishes, facial recognition, built-in cameras, and Matter/Thread on most models. The Schlage Encode Plus? $299. The Level Lock Pro? $349. Real products, real advantages — not on this list.
What you keep: fingerprint readers, keypads, auto-lock, remote access, physical key backup, and smartphone control. The stuff that actually gets you through your front door every day.
But none of that matters if the lock doesn’t physically fit your door.
Will It Fit Your Door? Measure These 3 Things First
Sixty seconds with a tape measure. Do it before you add anything to your cart.
Backset: Distance from the door’s edge to the center of the deadbolt hole. It’s either 2-3/8" or 2-3/4". Most smart locks fit both, but a few only fit one.
Door thickness: Standard is 1-3/8" to 1-3/4". Older homes sometimes run up to 2". If yours is over 1-3/4", you need a model with an extension kit or one that explicitly lists your thickness.
Deadbolt style: Single-cylinder (key outside, thumb turn inside) is what 90% of homes have. Every lock on this list supports it. Double-cylinder? Your options shrink fast.
Quick version: standard single-cylinder deadbolt on a door under 2" thick? Every lock here fits. Anything non-standard, I flag it per product below.
The 6 Best Smart Locks Under $200
| Best for | Price | Unlock Methods | Battery | Hub/Sub? | |
|---|---|---|---|---|---|
| ULTRALOQ U-Bolt Pro WiFi | Overall | $153 | Fingerprint, keypad, app, key | 4 AA | No / No |
| August Wi-Fi Smart Lock | Renters | $200 | App, auto-unlock, key | 2 CR123 | No / No |
| eufy S230 | Fingerprint | $200 | Fingerprint, keypad, app, key | Rechargeable | No / No |
| Yale Assure Lock 2 | Keypad-only | $159 | Touchscreen keypad, key | 4 AA | No / No |
| Aqara U200 | Smart home | $170 | Fingerprint, keypad, Home Key | Rechargeable | Hub for remote / No |
| Wyze Lock Bolt | Under $100 | $80 | Fingerprint, keypad | 4 AA | No / No |
That table tells you 80% of what you need. Here’s the other 20%.
Best Overall: ULTRALOQ U-Bolt Pro WiFi
Price: ~$153 | Best for: People who want everything without paying for everything
Fingerprint reader, backlit keypad, app control, auto-unlock, physical key backup — and built-in WiFi so you don’t need a $40 bridge to check your lock from work. ANSI Grade 1 certified (commercial-grade security). IP65 weatherproof. Smart lock installation takes about 15 minutes with a Phillips screwdriver.
The honest drawback: battery life. WiFi eats power. You’ll get 3-6 months from four AA batteries depending on WiFi usage. Keep spares handy.
App: Functional, not pretty. Regular updates, remote code sharing, schedule control.
Best for Renters: August Wi-Fi Smart Lock (4th Gen)
Price: ~$200 | Best for: Anyone who can’t replace their deadbolt
A retrofit smart lock — mounts inside your existing deadbolt. Landlord’s key still works outside. Installation takes 10 minutes. No drilling. Reverse it at move-out in under 5 minutes. Built-in WiFi, auto-unlock via geofencing, and DoorSense tells you whether your door is actually closed.
The honest drawback: no keypad, no fingerprint reader. Phone dies? You’re using the physical key. Uses CR123 batteries (~$8-10 per swap every 6 months) instead of standard AAs.
App: One of the best. Clean, reliable notifications, easy guest sharing.
Best Fingerprint Lock: eufy S230
Price: ~$200 | Best for: People who hate fumbling with phones and codes
Recognizes your fingerprint in 0.3 seconds. Touch, click, walk in. Touchscreen keypad, built-in WiFi, physical key backup. BHMA certified, IP65 rated for -22°F to 158°F. No hub, no subscription — eufy doesn’t paywall a single feature.
The honest drawback: built-in rechargeable battery, not swappable AAs. Lasts about a year, then you plug in a USB-C cable for a couple hours. Lock still works while charging — but you’ve got a cable hanging off your front door.
App: Feature-heavy (it handles all eufy products), which feels cluttered if you only own the lock.
Best Keypad-Only (No Phone Required): Yale Assure Lock 2
Price: ~$159 | Best for: People who just want to punch in a code
Touchscreen keypad, 250 access codes, auto-lock, physical key backup. Fits backsets of 2-3/8" and 2-3/4" with door thickness up to 2-1/4" — widest compatibility on this list. Punch in your code. Door opens. Your grandmother can use this keyless entry door lock.
The honest drawback: Bluetooth only at this price. Remote access requires Yale’s WiFi module ($79 extra), pushing total to $238. If you need to unlock from work, this isn’t the one.
Four AA batteries, 9-12 month lifespan. Hard to beat for simplicity.
Best for Smart Home Junkies: Aqara U200
Price: ~$170 | Best for: The person with 14 smart devices and a Home Assistant dashboard
Matter over Thread — works natively with Apple Home, Google Home, Alexa, and SmartThings. Apple Home Key support for iPhone/Watch tap-to-unlock. Fingerprint reader, keypad, NFC. If your house runs on smart home gear and you want your lock talking to everything, this is it.
The honest drawback: remote access requires an Aqara hub (~$60), pushing total to ~$230. Without it, Bluetooth and fingerprint still work locally. Rechargeable battery, ~6 months. Also accepts AAA backup.
Best Under $100: Wyze Lock Bolt
Price: ~$80 | Best for: Budget buyers who still want biometrics
Fingerprint reader (50 prints), backlit keypad (20 codes), auto-lock, and a built-in alarm after 5 failed attempts. Full deadbolt replacement, 15-minute smart lock installation. For $80, that’s remarkable.
The honest drawback: Bluetooth only. No WiFi, no remote access. Build quality is noticeably cheaper — the plastic feels like plastic. Four AA batteries last about a year.
App: The Wyze app works, but it’ll try to sell you cameras and subscriptions every time you open it.
Before You Buy: Renters, Cold Weather, and the Battery Question
You’ve picked your lock. Three things that might change your mind.
Renters: the August is your safest bet — landlord’s key works, remove it in 5 minutes at move-out. If your landlord is fine with a full swap, the Wyze at $80 is easy to reverse. Keep the original hardware in a drawer.
Cold weather: fingerprint readers can fail below 20°F. Cold shrinks skin moisture and kills capacitive sensors. Locks with physical keypad buttons (ULTRALOQ, Wyze) work in any temperature. Swap alkaline batteries for lithium before winter — alkalines crater in sub-freezing temps. Keep a physical key in your wallet, not your junk drawer.
Batteries: AAs beat built-in rechargeables. AAs die? Thirty-second swap. Rechargeable dies? Find the cable, plug in, wait. The eufy and Aqara use rechargeables — worth knowing. Everything else on this list takes standard AAs or CR123s.
One more: stick with brands that update their apps consistently. August, Yale, eufy, and ULTRALOQ all have multi-year track records. If a company killed their last lock’s app after two years, their current one is a gamble.
The Bottom Line
You came here because budget smart lock lists kept sneaking in $300 picks. Now you have six options — all under $200, all fitting standard doors, none requiring subscriptions.
One answer: the ULTRALOQ U-Bolt Pro WiFi at $153. Fingerprint, keypad, WiFi, Grade 1 security, no hub, no subscription. It does everything well, nothing badly, and you’ll have it installed before your coffee gets cold.
If you rent: the August Wi-Fi Smart Lock. Mounts over your existing deadbolt, reverse it in 5 minutes when you move.
A $150 smart deadbolt in 2026 is genuinely good hardware. You’re not settling — you’re just not overpaying. Now stop researching and go lock your door with your fingerprint like it’s the future.
