Home security systems have grown common in the United States, with renters installing their own systems or buyers bringing home security with them when they move. That’s led to a new kind of problem: On move-in day, people are discovering security systems already installed and waiting for them.
An existing security system can seem a little ominous, especially if you’re not sure where it came from. Fortunately, this home technology is usually harmless and can even help keep you safer. Here’s what to do if you find this type of security surprise.

Contact the landlord or owner right away
Get to the bottom of this mystery by making some quick calls. If you’re renting, message your landlord and ask about the system, what it’s for and how you can use it. If you’re a buyer, contact the seller’s real estate agent (try to avoid contacting the seller directly) and ask for an explanation of the system, if it works and why it was left behind. You need to get answers ASAP before you decide what to do next.
In the meantime, you can continue moving in. If the system looks like it’s powered on, we recommend shutting it off for privacy until you find out what’s going on.

Consult your lease or buying agreement
While you’re waiting for direct answers about the unexpected security devices, look up your lease or buyer’s agreement and see if there’s any section about home security. Check whether it mentions an existing security system, what will happen to the security system — and especially who’s responsible for it or has to pay for it’s removal. Leases in particular often have a section about security devices and what the landlord is responsible for. You’ll want to know exactly what’s in writing.
If it’s the landlord’s security system, it’s usually legal for them to install and control it, although most landlords prefer to keep security devices like home security cameras outside the rental. Tenants do have rights, including a right to privacy, so if the system feels invasive, you can absolutely complain and even consult a lawyer about your options. At minimum, a landlord should have told you about the system and given you a code to arm and disarm it.
If you’re a homebuyer, this is the time when you decide if you want to keep the system or have it removed. If you’re not too far along in the buying process, you may be able to ask the seller to pay for the alarm system’s removal as part of the buying agreement. Otherwise, you should be able to dismount most devices with a screwdriver, although some panels may need wiring work. Talk to your real estate agent about the details.
Check security system power and components
Explore the nuts and bolts of the security system and get to know it a little better. See if it’s powered on, or if you need to flip a breaker or plug in a hub to turn it on (or keep it off, if you’re nervous about privacy). Look for a model number on the keypad or hub, and look up the system online to learn about it.
Check for all system components to see what’s included and where any sensors or cameras are. In some cases, part of the system, like the keypad or hub, may have been removed, which renders the system useless unless you order a replacement.

Fully wipe the system (if possible)
The last thing you probably want is a security system in your home that a stranger can log in to remotely and use or even spy on you with. If you intend to keep using the security system or have permission from your landlord to “own” the system while you’re renting there, look for the proper way to wipe the system and set up a new account.
In most cases, you’ll need access to the old account to do this. With a SimpliSafe system, for example, you can log in to an account, go to System Settings, and choose the reset option to wipe it. You may have to require the home seller to do this part before they move out.
It’s also a good idea to call the security company’s customer service line. If you provide them with your address and related information, they may be able to look up accounts to see if any active accounts are registered in your home — or provide you with additional useful advice.
Check subscription details
When you look up your system and contact the security company and/or previous owner, see if the security system needs a subscription.
Some security systems, like those from ADT or Frontpoint, require a subscription to work at all. Others may require at least a monthly fee for managing the system yourself. Some, like Arlo’s security system or Ring Alarm systems, have a free tier or offer core features at no charge. You need to know what fees you’re dealing with before making final decisions. Big brands can charge over $50 per month for using security systems with monitoring, but you can find the feature for around $20 too.

Contact the security brand if necessary
If you have a system that was professionally installed or that requires a subscription to operate, it’s time to call the brand’s support number and ask if the company will reboot the system for you. Brands like ADT, Vivint, Frontpoint and others often require a formal request, and can remotely test the system for you. They may need to have a local dealer come out as well. You’ll have to start a new contract at this time, so be aware of the company’s price tiers.
Create your own account and set up the system
With the system wiped and ready, you can download the app and set up your own account. Be ready with a secure password and the login information for your home Wi-Fi router to set up the system. Take the steps slowly so you can learn how the system works, what it does, how it sends alerts and your options for arming/disarming it.
If you run into trouble at this point, we recommend calling customer support for a walk-through.

Test the system
With the system under your control, it’s time to test it out. Go through the app settings to check the details, work on arming and disarming it, and see how sensitive the sensors are. Practice sending or keying in the disarm code. Have your family and loved ones practice using the system, too. Now you’re ready to adopt it as your own!
