Best Smart Lock Under $200
A reliable smart deadbolt no longer costs a fortune. We compared keyless entry systems from Schlage, August, Kwikset, Yale and Aqara to find the best smart lock under $200 that balances security, app features and how easy it is to fit to a standard US door.
Quick answer
The Schlage Encode Smart WiFi Deadbolt is our top pick: it has Wi-Fi and a backlit keypad built in, so it needs no hub or bridge, and it carries an ANSI/BHMA Grade 1 security rating.

Schlage Encode Smart WiFi Deadbolt (BE489WB)
Best OverallPros
- Wi-Fi built in, so no hub or bridge is needed
- Backlit keypad plus a physical key override
- ANSI/BHMA Grade 1, the highest residential rating
Cons
- Sits right at the top of the $200 budget
- Wi-Fi radio drains AA batteries faster than Bluetooth locks
The Schlage Encode replaces your existing deadbolt entirely and puts the Wi-Fi radio inside the lock, which is the single biggest reason it wins here. Most rivals at this price either need a plug-in bridge or a separate hub before you can lock the door from your phone. With the Encode you fit it, join it to your 2.4GHz network in the Schlage Home app, and you are done.
It is one of the few smart deadbolts at this price certified ANSI/BHMA Grade 1, the top residential grade for strength and durability. You can store dozens of access codes, share time-limited codes with guests, and it works with Amazon Alexa and Google Assistant. There is also a keyway, so a dead battery or a router outage never locks you out. Owner reviews consistently flag battery life as the main gripe, which is the expected trade-off for an always-connected Wi-Fi lock.
August Wi-Fi Smart Lock (4th Gen)
Best for Keeping Your Existing KeyPros
- Wi-Fi built in, no separate August Connect bridge needed
- Keeps your existing deadbolt, exterior hardware and keys
- Auto-Lock, Auto-Unlock and DoorSense open-door detection
Cons
- No keypad in the box, the August Smart Keypad is sold separately
- CR123A cells are more expensive to replace than AA
The August Wi-Fi Smart Lock is the one to buy if you do not want to change how your door looks from the outside. It mounts on the inside over the thumb turn of your existing deadbolt, so the exterior cylinder and every key you already own keep working exactly as before. That also makes it the friendliest option for renters, since nothing on the outside of the door changes.
The 4th generation shrank the body considerably and, unlike the older August Smart Lock Pro, has Wi-Fi built in, so the old plug-in Connect bridge is no longer required. Auto-Unlock as you arrive home and DoorSense (which tells you the door is actually closed, not just locked) are the standout features. Note the power source: it takes two CR123A lithium cells rather than AA batteries, and real-world life is usually a few months rather than a year. Codes and PIN entry require adding the separate August Smart Keypad.
Kwikset Halo Wi-Fi Smart Lock
Best Budget Keypad DeadboltPros
- Usually the cheapest hub-free Wi-Fi keypad deadbolt
- SmartKey Security lets you rekey the cylinder yourself in seconds
- Works with Alexa and Google Assistant out of the box
Cons
- Not rated as highly as Schlage for pick and bump resistance
- App and Wi-Fi connection can be less consistent than Schlage's
The Kwikset Halo does the same core job as the Schlage Encode, a full deadbolt replacement with a keypad and Wi-Fi on board, for noticeably less money. If your priority is getting hub-free app control and guest codes for the lowest possible outlay, this is the one that fits comfortably inside the budget rather than pressing against it.
Its standout practical feature is SmartKey Security, Kwikset's rekeying system, which lets you re-key the cylinder to a new key yourself without calling a locksmith. That is genuinely useful for a rental, a house move, or after losing a key. The trade-offs versus Schlage are security pedigree and app polish: Kwikset's cylinders have historically been criticized for pick and bump resistance, and owner reviews mention occasional Wi-Fi dropouts that need a re-pair.
Yale Assure Lock 2
Best Upgrade PathPros
- Touchscreen keypad, available key-free or with a keyway
- Slimmest interior housing of the deadbolts here
- Smart module can be swapped later for Wi-Fi, Z-Wave or Matter over Thread
Cons
- The base model is Bluetooth only, so remote access costs extra
- Adding the Wi-Fi module pushes the total over $200
The Assure Lock 2 is Yale's current US deadbolt line, and its differentiator is modularity. The lock ships with a Bluetooth radio and a slot on the back for a smart module. If you only ever unlock the door from the doorstep or with a code, the base Bluetooth version does everything you need and lands under $200. Later, if you want remote access, you buy the module rather than a new lock.
There are Wi-Fi, Z-Wave and Matter over Thread modules, which is a genuinely useful hedge given how quickly smart home standards shift. It comes in a key-free version for a very clean look, or a keyed version if you want a physical backup, and the interior housing is the most compact of the deadbolt replacements on this list. Be clear-eyed about the cost: the lock plus a Wi-Fi module is no longer a sub-$200 purchase, which is exactly why the Schlage Encode outranks it here.
Aqara Smart Lock U100
Best for Apple Home UsersPros
- Five ways in: fingerprint, keypad, app, Apple Home Key and a physical key
- Apple Home Key means you can tap an iPhone or Apple Watch to unlock
- Fingerprint reader is fast and works well with gloves off in cold weather
Cons
- Needs an Aqara hub for remote access and notifications
- Non-Apple households get less out of it than the Schlage or Kwikset
The U100 is the entry-access specialist here. It is a full deadbolt replacement with a fingerprint reader and keypad on the exterior escutcheon, plus NFC support for Apple Home Key, which lets you unlock by tapping an iPhone or Apple Watch against the lock. That works even if the phone battery is flat enough that the screen will not wake, which is a real advantage over app-only locks.
The catch is the connectivity model. Out of the box the U100 talks Bluetooth, so remote locking, unlocking and away-from-home notifications need an Aqara hub on your network. If you already own one, this is comfortably the most flexible lock on the list for the money. If you do not, factor the hub into the budget, and a Wi-Fi lock like the Schlage or Kwikset will make more sense.
What to check before buying a smart lock under $200
Measure your door before you order anything. Standard US deadbolts use a backset of either 2-3/8 inches or 2-3/4 inches (the distance from the door edge to the center of the bore), a 2-1/8 inch cross bore, and a door thickness of 1-3/8 to 1-3/4 inches. Almost every lock on this list adapts to both common backsets, but doors outside those ranges, along with mortise locks and multipoint patio doors, need a different product entirely.
Then decide how the lock will reach the internet. Locks with Wi-Fi built in, like the Schlage Encode, August 4th Gen and Kwikset Halo, need nothing else but use batteries faster. Bluetooth locks like the base Yale Assure Lock 2 and the Aqara U100 sip power and cost less up front, but remote access requires a hub, bridge or module, so compare the total price of the setup rather than the price on the box.
Mistakes to avoid when choosing a smart lock
Do not overlook the backup entry method. Key-free models look cleaner but leave you with no mechanical way in if the electronics fail. Either choose a version with a keyway, or make sure the lock has external emergency power contacts (many keypad deadbolts let you hold a 9V battery to the base to power the keypad long enough to enter a code).
Do not judge a lock only by its app. The deadbolt itself is still the thing resisting a kick or a pry bar, so check the ANSI/BHMA grade, and fit 3 inch screws into the strike plate so they bite the door frame stud rather than just the jamb. And check the standard the lock speaks: Matter, Z-Wave and Apple Home Key are open and portable between systems, whereas a lock tied to one brand's own hub limits what you can add later.
FAQs
Are smart locks under $200 secure?
Yes. Locks from Schlage, Yale and Kwikset use the same deadbolt hardware as their mechanical equivalents, and the Schlage Encode is certified ANSI/BHMA Grade 1, the highest residential rating. The weak point on most doors is the strike plate and frame, not the lock body.
Do I need a hub for a smart lock?
It depends on the model. The Schlage Encode, August Wi-Fi Smart Lock and Kwikset Halo have Wi-Fi built in and need no hub. The base Yale Assure Lock 2 and the Aqara U100 are Bluetooth, so remote access needs a module or hub.
Can I install a smart lock myself?
Yes. A retrofit like the August takes about 10 minutes with a single screwdriver. A full deadbolt replacement such as the Schlage, Kwikset, Yale or Aqara takes roughly 20 to 30 minutes if the door is already bored for a standard deadbolt.
What happens if the batteries die?
All of these warn you in the app well ahead of time. Keyed models let you use the physical key, and many keypad deadbolts have external contacts that let you hold a 9V battery against the lock to power it long enough to enter your code.
Do smart locks work with Alexa or Google Home?
The Schlage Encode and Kwikset Halo work with both directly over Wi-Fi. The August works with both as well. The Aqara U100 is aimed at Apple Home and Apple Home Key, and needs an Aqara hub for voice control in other ecosystems.
Can I still use my original key with a smart lock?
Only with a retrofit. The August mounts on the inside over your existing deadbolt, so the outside cylinder and all your current keys keep working. Deadbolt replacements give you new keys, or no keyway at all on key-free versions.
How long do smart lock batteries last?
Expect roughly 6 to 12 months from a set of 4 AA batteries in a Wi-Fi keypad deadbolt, and less in heavy-traffic homes. The August is the outlier: it uses two CR123A lithium cells and typically runs a few months per set.
Are smart locks compatible with all door types?
No. These are all standard single-cylinder deadbolt products. Mortise locks, multipoint patio and sliding doors, and unusually thick or thin doors need purpose-built hardware, so check the manufacturer's fit guide first.
What is the warranty on a smart lock under $200?
Mechanical parts are often covered for the life of the product, while the electronics carry a shorter term. Schlage covers Encode electronics for 3 years, Yale and Kwikset for 1 year, and August covers its lock for 1 year.
Can I grant temporary access to guests?
Yes. Every lock here supports guest access, either as time-limited PIN codes on the keypad models or as scheduled virtual keys in the app. Codes can usually be set to expire on a date or repeat on a weekly schedule.
Our verdict
For most US homes the Schlage Encode Smart WiFi Deadbolt is the best smart lock under $200: Wi-Fi and a keypad built in, no hub, and an ANSI/BHMA Grade 1 rating. If you want to keep your existing deadbolt and your current keys, buy the August Wi-Fi Smart Lock (4th Gen) instead, and if you simply want the lowest price for a hub-free keypad lock, the Kwikset Halo is the value choice.
