The Door and Window Alarm with Deactivation Key is an effective alarm that protects your doors or windows. When a door or window is opened, an alarm will sound alerting you.


The Door and Window Alarm with Deactivation Key is an effective alarm that protects your doors or windows. When a door or window is opened, an alarm will sound alerting you. This unique model can only be turned off with the deactivation key.

This simple device can be used around the home to alert you to unauthorized entry (or exit). It can also protect cupboards, cabinets, even drawers where you want to make sure a child isn't getting into or going where they shouldn't.

The 105-decibel alarm lets you know that a door or a window has been opened. Use these wherever you want additional security such as on all ground floor openings. Our brilliant customers have also found another use for this particular safety device.

Have a problem with an adolescence leaving when they aren't supposed to?

TIP: Super Glue the battery compartment shut so it can't be disabled.

As parents, all too often we feel like we have absolutely no control over what our teenagers do. They have reached that age where they feel they deserve their freedom and they will get it one way or another - even if they have to sneak out of the house.

Are your children guilty of sneaking out of their bedroom window? Have they even braved the front door?

What can you do to prevent your teen from sneaking out?

Has your teen ever snuck out the window?

Having a talking to hasn't worked, and not even being grounded seems to help. Maybe for a week or two…but then, there they go again. Expressing concern for their safety is of no effect. The consequences are worth the fun.

Unfortunately, short of installing security bars on your windows, and pad-locking all the doors, there’s not a whole lot you can do to keep them from sneaking out at night.

Is a Window Alarm Right for You?

There are many inexpensive door and window alarms on the market today. The problem with most of these alarms is that they are meant to sound off when someone is entering the house. They have on/off switches and are too easy for your teenager to just turn them off before slipping out. When they return, they can just turn them back on again. All the while, you are "left in the dark".

There is an alarm solution to this ever-growing problem. A Door and Window Alarm with a deactivation key. Because this wireless alarm is self-contained, you are able to arm and disarm the unit with the key. The inexpensive price comes in handy when you need to cover several windows and doors that are being used for a swift escape.

The Door/Window Alarm with Deactivation Key installs quickly and cleanly without any drilling or wiring.

Just install the main unit and the magnetic bar on the frame of the door or window, using the powerful adhesive tape. When the door or window is opened, the alarm will emit an intense 105dB siren.

This is a very economical way to keep someone out of someplace you don't want them to be, or alert you to their presence. Batteries are included.

I bought several of these sensors in the hopes of alerting me if my teenager tried to leave the house while I was asleep, which is one of uses specifically listed. I found many problems with the sensors making them unusable for this purpose even with many work arounds. Most notably was that the adhesive was not strong enough to hold the sensors to the frame of the window, not even for a day. Several popped of during the night scarring is to death and those that didn't pop off during the night popped off the next day while we were out, alarmed all day causing the batteries to run out. The work around based on posts was to replace the adhesive with stronger options you purchase from your local hardware store. Done. This sensor seems like a good option as it uses a key to turn off the alarm and not an on/off switch but it also turns off when you shut the door or window so a kid could open it and shut it so quickly that before it registers what just happened, especially if you are sound a asleep, you think you are imaging it, it needs to continue sounding until YOU turn it off or at least longer that a brief second. Then there is the battery issue, it's too easy for the kids to take the batteries out, it's on the front of the unit and once removed they have easy access. The work around is to super glue the compartment but the down side is that you have to replace the whole unit when the battery runs out. That was something I was willing to accept so that's what I did, however, as noted above, I had two units fall off during the first day running the batteries down so I was down two units the first day. Not good. And last but not least. The kids can hack the sensor so easily by simply taping a magnet over the main unit letting them come and go as they please with no detection. None, nada. Bottom line.... alarm systems using any kind of magnet system is meant to deter people from getting in but will NOT keep people in. The only use I can see for these alarms is those needing a warning for handicap, seniors and/or children that won't understand how to disarm the system but an extra layer of security is needed the event they wonder off.

Teenage daughter figured out to remove batteries from the front of the alarm. The batteries shouldn't be easy to access. Should be on the back so if it is removed the alarm goes off. Not really good for keeping kids from sneaking out.

These are a great deal! I use them on all of my downstairs windows. I would have given these a five star rating except they aren't fool-proof for keeping your teen from leaving through a window.

This alarm can be good for keeping teens in, but you need to glue the battery door shut because your teen could simply remove the batteries to turn off the alarm before opening the window. In addition, if you also use it for a door, during the day you may need to put the deactivation key in the alarm so you can use the door without alarming. If you leave the key in the door alarm, all the teen needs to do is take the key while the door is closed, hide it, and use it to disable the alarm for their window.
