Changing the locks is not enough: inherited cameras, alarms, routers and smart appliances may still be linked to a previous owner’s account unless they are properly reset and transferred.
New homeowners are often told to change the locks, but that is only part of the job. Smart cameras, video doorbells, connected thermostats, alarm panels and app-controlled locks can stay tied to a seller’s account after the keys change hands, leaving a property exposed unless those devices are checked and reset.
Cybersecurity specialist Kurtis Baron of Echo Secure told Family Handyman that it is safer to assume the previous owner can still reach inherited devices unless proven otherwise. Nathan Connell, founder and editor of Future Technology, advised testing each device through its manufacturer’s app. If the app rejects the set-up because another account already owns the device, that is a clear warning sign. Connell also said new owners should inspect any shared-users list, because access may have been granted to relatives, contractors or tenants as well as the seller.
Baron recommends resetting every connected device in the home, not just the obvious ones. That includes cameras, alarms, smart locks, thermostats and connected appliances. The Federal Trade Commission has warned that some internet-linked products, including light bulbs and security systems, are easy to overlook because they do not always look like smart devices. Where possible, the previous account should be removed, the device should be factory reset, and it should then be registered under the new owner’s details. Google’s moving guide for Home and Nest devices says some products must first be released by the former owner before they can be added to a new account, while Ring says a device must be removed through the app for ownership to transfer properly. Simply uninstalling the app or taking the device off the wall is not enough.
Connell also urged homeowners to clear any old keypad codes or guest permissions, especially on smart locks and alarm systems. The router deserves the same attention, because most connected devices depend on it for internet access. The FTC says the router is central to privacy in the internet-of-things environment, and Baron advised replacing inherited networking equipment rather than reusing it. At a minimum, new occupants should install their own Wi-Fi password and review the list of connected devices for anything unfamiliar.
Some older products may be better replaced than reset, particularly if they can no longer receive security updates or cannot be fully wiped. Until the ownership issue is resolved, new homeowners should not depend on an inherited lock or camera as a primary security measure. Connell suggested asking sellers before completion for a full inventory of connected devices, together with manuals, hub details and transfer instructions. The FTC also recommends that sellers leave behind any documentation that explains smart features and confirm that all accounts and shared access have been removed. Baron said that requirement should ideally be written into the closing paperwork, giving buyers a clear record that access has been revoked before they move in.
