Secure your home and stop teen escapes with the Door Window Alarm for Kids from TBOTECH. This stick-on alarm mounts to any door or window and blares a 105 dB siren when opened—loud enough to alert you to intruders or a kid sneaking out. Its secret weapon? A deactivation key. Remove it, and no one’s turning off the alarm without you, making it a top pick for parents and homeowners alike.

Keep Kids from Sneaking Out with Smart Design

Setting it up is simple: use the included adhesive tape to attach the main unit and magnetic bar to a door or window frame. At 2.5 x 1.5 x 0.5 inches (3 inches with the key inserted), it’s compact and fits sliding doors, bedroom windows, or front entrances.

Three LR44 batteries (included) keep it running, and the magnetic sensor triggers the siren when the connection breaks. It’s been a TBOTECH best-seller for years, trusted for stopping unauthorized exits and entries. Use it on ground-floor openings or anywhere kids might test boundaries.

Tamper-Proof Your Alarm for Extra Control

Teens can be clever—they might try opening the unit to remove the batteries and disable it. Our customers have given us a fix: superglue the battery compartment shut.

This makes it truly tamper-proof, ensuring the alarm stays active no matter what. (Note: You’ll need to replace the unit when the batteries run out, but it’s worth it to keep kids from sneaking out unnoticed.) This trick, paired with the deactivation key, gives you the upper hand against even the sneakiest teen while doubling as solid home security.

Not just for parents—this alarm works anywhere you need protection, like RVs, dorms, or garages. Pair it with our Panic Alarm for extra safety on the go. With a 1-year warranty and TBOTECH’s proven quality, it’s a small investment for big peace of mind.

Sounds a 105 dB siren when door or window opens.
Installs with adhesive tape—no tools or wiring needed.
Deactivation key and batteries included for control.

Don’t risk losing sleep or safety—order this Door Window Alarm for Kids now and prevent sneaking out for good!

Advantages

It's loud! Should work for what we purchased it for. The delivery was kind of slow, but that's the USPS for us.

Advantages

Easy to use and install. Noise definitely gets your attention if there's an issue.

Disadvantages

The magnetic part took extra reinforcement and you have to glue the battery part shut for extra protection. Also, the way our windows are constructed, the sensors make it impossible to open them once in place.

Comment

They are nice for what they are, but we have a primary security system now and will most likely uninstall them when the batteries go dead. Until then, they do help with peace of mind.

Advantages

I think w/ the key it’s just intimidating to keep my son from sneaking out. I also told him a little fib that it’s programmed to my phone so I’ll get an alert.. Sometimes ya gotta do what ya gotta do.

Disadvantages

I wish it wouldn’t shut off once the door/window is closed. If they move quickly we probably wouldn’t hear it that quickly if sleeping in other room.

Comment

All in all I don’t regret my purchase.
