Schlage Encode Plus is our top pick for most homes. Built-in Wi-Fi, ANSI Grade 1, works with Apple Home Key. Yale Assure Lock 2 is best for renters (reversible installation). August Wi-Fi Smart Lock is best if you want to keep your existing deadbolt. Avoid cheap off-brand locks from Amazon.
Why Trust a Locksmith's Smart Lock Opinion?
Because we install and troubleshoot these things every day. Tech reviewers test a smart lock for 2 weeks in their house. We've installed hundreds of each model across dozens of different door types in South Florida's heat, humidity, and salt air. We know which ones hold up and which ones fail.
According to a 2025 Parks Associates survey, 38% of smart lock owners had trouble with installation or connectivity. That tracks with what we see. The lock itself is usually fine. It's the installation, Wi-Fi pairing, and door compatibility that cause headaches. That's where a professional smart lock installation pays for itself.
What's the Best Smart Lock Overall?
Schlage Encode Plus. Here's why. Built-in Wi-Fi (no hub needed). ANSI Grade 1 rated (the highest security grade). Works with Apple Home Key, Amazon Alexa, and Google Home. Supports up to 100 access codes. Battery lasts 6-12 months on 4 AA batteries.
We've installed over 200 Schlage Encode locks in the past two years. The failure rate is under 2%. Compare that to some Amazon off-brands where we get callback rates of 15-20%. Schlage also has a responsive warranty team. If something fails, they ship a replacement fast.
The Encode Plus retails for about $280-$330. With our installation, total cost is $350-$450. Considering it replaces your deadbolt AND adds smart features, that's solid value.
What About Yale Assure Lock 2?
Best choice for renters and people who want flexibility. The Yale Assure 2 is modular. You can swap between Wi-Fi, Z-Wave, and Zigbee modules without replacing the whole lock. The installation is non-destructive and reversible, which matters if your lease requires you to restore original hardware when you move out.
It's ANSI Grade 2 (not Grade 1 like Schlage). For most apartments and condos, Grade 2 is fine. It supports 250 access codes and works with all major smart home platforms. About $220-$280 retail, $300-$400 installed.
Is August Smart Lock Worth It?
Yes, if you want to keep your existing deadbolt. August replaces only the interior part of your deadbolt. The exterior looks exactly the same. Your existing keys still work. But now you also have app control, auto-lock, auto-unlock (based on phone GPS), and guest access codes.
The downside: August requires the August Connect Wi-Fi bridge (sold separately, $80) for remote access. Without it, the lock only works via Bluetooth when you're within 30 feet. The bridge adds cost and is one more thing that can lose connection.
Which Smart Locks Should You Avoid?
Anything under $100 from an unknown brand on Amazon. We've seen locks from Ultraloq, Lockly, and various white-label Chinese brands fail within 6 months. Common failures: motor burns out, touchscreen stops responding in Florida heat, and Bluetooth disconnects constantly.
Honestly, I'd also skip Kwikset Halo for now. We've had more connectivity complaints with the Halo than any other mainstream brand. The hardware is fine but the Wi-Fi module drops connection frequently, especially in homes with mesh routers. Kwikset may fix this in a future firmware update, but as of April 2026, it's not where we'd put your money.
What About Smart Locks and Florida Weather?
Heat and humidity matter more than most reviews mention. South Florida summers hit 95+ degrees with 90% humidity. Direct sun on a south-facing door can push the lock's surface temperature over 140 degrees. Cheap plastic components warp. Battery life drops by 30-40% in extreme heat.
Schlage and Yale both use weather-resistant housings rated for outdoor exposure. We recommend the satin nickel finish over brass or matte black for coastal properties because it resists salt air corrosion better. If your door gets direct afternoon sun, consider a keypad lock instead. No touchscreen to cook in the sun.
Do You Need a Locksmith to Install a Smart Lock?
You can DIY it, but here's why most people call us. The physical installation is straightforward if your door has a standard prep. But the Wi-Fi setup, app configuration, code programming, and integration with Alexa/Google/HomeKit take time and patience. We do the whole thing in 45-90 minutes.
The other reason: if the lock doesn't fit your door (wrong backset, wrong bore size, door too thick), a locksmith can modify the door prep on the spot. A DIY installer discovers the problem after they've already removed the old lock and has no deadbolt on their front door until they figure it out.
