You moved in last weekend. The keys were handed over at closing, you changed the garage code, and things feel like yours. But the front door has a smart lock the previous owners installed, and it's still connected to an account you don't control.

That's not a hypothetical. It happens constantly.

Smart locks look reassuring. No fumbling for keys. Auto-lock when you leave. Access codes for the dog walker. But when you buy a home with one already installed, you're inheriting a device that may still be linked to someone else's phone, their family members, their Airbnb guests, or their property manager. Unless you reset it completely, those access permissions don't go away.

Here's what to actually do.

Step 1: Identify the Brand and Model

Flip the lock over or check the keypad for a logo. Common brands are Schlage, Yale, Kwikset, and August. The model number matters because each one has a different reset process. Take a photo before you do anything else.

Step 2: Do a Factory Reset, Not Just a Code Change

Changing the entry code on a smart lock doesn't disconnect the device from the previous owner's app. That just gives you a new PIN while they potentially still have remote access from their phone.

A factory reset wipes all user accounts, access codes, and app connections. The exact steps vary by brand. Schlage Encode requires holding the Schlage button and the 9 key simultaneously until the keypad flashes. Kwikset requires a different button combination depending on the model. August involves holding the reset button inside the battery compartment. Don't guess. Look up the exact steps for your specific model before you touch anything.

Step 3: Create a New Account From Scratch

Once the lock is reset, download the manufacturer's app and add the device as if it's brand new. Do this before you set any access codes. This makes you the primary owner with full admin control, and nobody else has a path in.

Step 4: Check If It Was Connected to a Smart Home Hub

Smart locks often talk to other devices. If the previous owner had a smart home system, the lock may still be linked to a hub in the basement or a Z-Wave bridge somewhere in the house. Any hub connected to their account could theoretically still reach the lock. Reset the hub too, or remove the lock from any hub you find before connecting it to your own setup.

Step 5: Turn On Two-Factor Authentication

Once everything is clean and under your account, enable two-factor authentication in the lock's app. This means even if someone got your login credentials, they'd still need your phone to get access. It takes two minutes and closes a real vulnerability.

What If You Can't Reset It Yourself?

Some locks require a technician, especially if the previous owner didn't leave documentation or the device has a non-standard configuration. That's a legitimate reason to call for help. A lock that might still be accessible to someone you've never met isn't a situation to leave unresolved.

If you just moved into a home with smart locks, cameras, or other connected devices, a full smart home audit covers all of this in one visit. You get confirmation that every device in the home is under your control, nothing is still tied to a previous account, and everything is configured correctly from the start.

The first week in a new house has enough going on. Your front door shouldn't be one of the things you're guessing about.
