Treasure Coast Locksmith provides August smart lock installation services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. August Smart Lock Pro is a retrofit smart lock that installs over the interior side of your existing deadbolt. Your exterior hardware stays the same, your existing key still works, and you gain smart features. Ideal for HOA communities with restricted exterior finishes.
$225-$345 installed.
August Smart Lock Pro has a unique approach to smart lock retrofitting. Instead of replacing your existing deadbolt with a full smart lock, it installs over the interior thumb-turn of your existing deadbolt. The exterior side of the door is unchanged - same key, same exterior hardware, same finish.
Only the interior side has a motorized unit that turns the deadbolt.
This approach is ideal for two specific situations. First, HOA communities with restricted exterior hardware - since August doesn't replace the exterior, you don't need HOA approval for any visible hardware change. Second, historic homes or architectural preservation concerns where you want smart features without disturbing the exterior aesthetic.
Treasure Coast Locksmith installs August Smart Lock Pro across every Treasure Coast city. Installation is fast (usually 30-45 minutes) because there's no exterior drilling or hardware replacement.

How August retrofit works
August Smart Lock Pro installs in three steps. First, the mounting plate attaches to the interior side of the existing deadbolt, replacing the decorative interior trim plate. Second, the drive spindle of the August unit engages with the existing deadbolt's thumb-turn mechanism.
Third, the August motor body attaches to the mounting plate, completing the install.
The critical piece is compatibility. August Pro works with most common residential deadbolts that have a standard thumb-turn on the interior side. Schlage B-series, Kwikset Signature, Baldwin Estate, and most Medeco/Mul-T-Lock deadbolts are compatible.
Deadbolts with non-standard interior trim or unusually shaped thumb-turns sometimes need adapter kits.
The Connect bridge (included in August Smart Lock Pro bundle) is a small plug-in device that sits near the door and relays Wi-Fi commands to the August via Bluetooth. Without Connect, August only works when your phone is in Bluetooth range. With Connect, you get full remote access, Alexa/Google integration, and HomeKit support.

August ownership tips
- Test your existing deadbolt thumb-turn first - if it's stiff, service the deadbolt before installing August.
- Place the Connect bridge within 30 feet of the lock for reliable Wi-Fi bridging.
- Use lithium batteries for longer life (12-18 months vs 8-12 for alkaline).
- Set up auto-unlock carefully - the GPS geofence can trigger too early if set too wide.
- Keep your mechanical key - August is a smart lock supplement, not a replacement for the key.
- For HOA communities, document the retrofit to confirm no exterior change was made.

August Smart Lock FAQs
Common questions about August Smart Lock installation.
How much does August Smart Lock installation cost?
August Smart Lock Pro installation runs $225 to $345 including hardware, installation, Connect bridge pairing, and app setup. The Connect bridge is included in the Pro bundle. Installation is typically 30-45 minutes, faster than full smart lock replacement because there's no exterior drilling.
Will August work with my existing deadbolt?
August Pro is compatible with most common residential deadbolts: Schlage B-series, Kwikset Signature, Baldwin Estate, Medeco, Mul-T-Lock, Yale, and Emtek. We verify compatibility onsite before installation. Deadbolts with unusual interior trim may need an adapter kit, which we stock.
Does August replace my key?
No. August retrofits over your existing deadbolt, so you continue using your current key for the exterior cylinder. August adds smart features (app, codes, auto-unlock) on the interior side without removing the mechanical key functionality.
Best of both worlds for many homeowners.
Do I need the Connect bridge?
For remote access (controlling the lock when you're not at home), yes. Without Connect, August only works when your phone is in Bluetooth range (~30 feet). With Connect, you get full remote control, Alexa/Google integration, and HomeKit support.
Pro bundle includes Connect.
Is August HOA-approved?
Yes, in virtually every HOA community. Because August is a retrofit that doesn't change exterior hardware, it doesn't need HOA approval for exterior hardware changes. The interior modification is homeowner discretion.
This is why August is the preferred smart lock for HOA-restricted communities.
How long does August battery last?
12-18 months on 4 AA lithium batteries with normal use. 8-12 months on alkaline batteries. Heavy use (many daily locks/unlocks plus auto-unlock triggering) shortens battery life.
The app shows current battery level and sends low-battery warnings 30+ days in advance.
Does August work with Apple HomeKit?
Yes. August Smart Lock Pro supports Apple HomeKit natively via Bluetooth. With the Connect bridge, you get full HomeKit remote access.
August is one of the best HomeKit smart locks because of the retrofit design - you keep your existing deadbolt and add smart features.
Can you install August on an impact-rated door?
Yes in most cases. Since August retrofits over the existing deadbolt, it doesn't affect the door's impact rating. Your original impact-rated deadbolt stays in place.
The August motor attaches to the interior side without any structural changes.
What if my deadbolt thumb-turn is unusual?
August Pro includes multiple adapter shims that fit most thumb-turn shapes. For unusual deadbolts (antique, historic, non-standard), we may need to special-order a custom adapter or recommend switching to a standard deadbolt. Compatibility check is always included in the installation quote.
Can August auto-unlock my door when I arrive home?
Yes. August supports auto-unlock via GPS geofence and Bluetooth proximity detection. You set up a geofence around your home in the app; when your phone crosses the geofence and Bluetooth range is established, the lock unlocks automatically.
Saves carrying keys for frequent trips in and out.
Is August a replacement for a deadbolt?
No. August is a supplement that adds smart features to your existing deadbolt. The mechanical deadbolt and the ability to unlock with a physical key both remain.
August automates the interior thumb-turn with a motor and adds app control, but the core lock is your existing deadbolt.
How long does August installation take?
Typically 30-45 minutes onsite including compatibility check, mounting plate installation, August motor attachment, Connect bridge setup, Wi-Fi pairing, app configuration, and 10-minute owner training. Faster than a full smart lock replacement because there's no drilling or exterior hardware work.
