The rule is simple. The phone does not come to bed. The argument is not. One more minute. One more video. One more “I’m using it for homework.”
The Phone Lock Box is the smaller box, for a nightstand. Put the phone in, set a time from 1 minute to 30 days, and the lid stays shut until that time ends. Calls and alarms still come through. The box does not block the signal.
The argument is the same every night. “One more minute” is a negotiation the phone is built to win.
You can settle it on a good night. You have to settle it again the next night, usually later than you meant to, with the phone already in a hand. The box moves that decision to before anyone is tired.
Reason 2
A screen-time limit lives on the phone the teen can dismiss. The limit and the loophole are the same device.
Downtime, an app limit, a focus mode: all of them can be tapped past. After that tap, they are in the app the limit was supposed to close. A lid does not have a “remind me in 15 minutes” button.
Reason 3
Taking the phone away turns you into the enemy. And the phone comes back in the morning anyway.
Confiscating it ends the night and starts a different fight. In the morning the phone is back, often dead, and the rule has to be renegotiated. The box leaves the phone in the room. It does not hand it over because someone asked.
Reason 4
Calls and alarms still come through. The box does not block the signal.
A parent can still call. An alarm still goes off. What cannot happen is picking the phone up to see who texted. Hearing it and holding it are different.
Reason 5
It can charge in the box. Morning is not a dead-battery fight.
A charging cable can pass through while the lid is locked. The phone can sit on the nightstand, plugged in, until the time you set.
Reason 6
You set the time before the argument. After 15 seconds, the lid holds that time.
Choose anywhere from 1 minute to 30 days. The screen blinks for 15 seconds, and any button in that window cancels it. After that, a running timer cannot be made longer. The decision is the one made before bed, not the one at 11:40.
Reason 7
Fortress mode has no code in the box. There is nothing in the nightstand to find.
Lockbox Only opens with the code that comes with the box and has no timer. Standard runs a timer and opens early with that same code. Fortress runs a timer and has no code in the box. For a real emergency, or a mistake, support can send a one-time code.

Questions, answered
Before you lock it.
No. It does not block the cellular signal. Calls and alarms still come through. What it blocks is picking the phone up.
No. The phone stays in the room, it can charge, and it opens at a time you set before bed. Taking it away is a different fight. This is a lock on the time, not a confiscation.
Lockbox Only and Standard: yes. The box comes with an override code. Fortress: no code is in the box. For a genuine emergency or a mistake, contact support and we can send a one-time code. On lockboxes sold after June 1, 2025, that code changes with every new Fortress cycle. You can also ask us to block override codes for your email.
After you start a timer, the screen blinks for 15 seconds. Press any button in that window to cancel. After that, Lockbox Only and Standard open with your override code. Fortress stays shut until the timer ends. You can't extend a running timer.
Anywhere from 1 minute to 30 days.
Yes. A charging cable can pass through while the lid is locked.
Removing the batteries does not reset the countdown. The timer stays in place until it finishes. Two AA batteries, included, last about 4–6 months.
