Quick answer: Change the router’s Wi-Fi password and admin password from the defaults (FTC), use WPA3 or WPA2 encryption (FTC), and for each smart lock or camera, change default passwords, turn on two-factor authentication and keep firmware updated (FTC; CISA).
⚠ Safety first:
- Battery smart locks: keep a backup key and replace batteries when warned.
- Hardwired doorbells and cameras: turn off the breaker; call an electrician if new wiring is needed.

⚠ When to call a pro: a cracked or split door frame; locks or doors damaged in a break-in (report to police first); doors that don’t fit their frames; and any hardwired lights, doorbells or cameras that need new wiring; that’s a job for an electrician (see breakers and outlets). Renters: ask your landlord before changing locks or drilling. Renting? See what you can fix vs. call your landlord.
