Unlock a bathroom or bedroom door without a key

How a privacy lock opens from outside

Bathroom and bedroom knobs and levers use a privacy lock: a push button or small turn on the inside that stops the knob from turning. There's no key cylinder, because the point is a little privacy, not keeping people out. They're designed to open from the outside without a key in an emergency, so manufacturers put a release in the outside knob, either a small round hole or a narrow slot right in the center.

The release works on the locking mechanism, not the latch. With a hole, a thin straight tool pushes a release pin and the button pops out, or on some brands you push in and turn. With a slot, a small flat tool turns the lock's spindle back to unlocked. Older knobs or decorative hardware sometimes have no release, and then you go around the lock: the latch has an angled side that a thin card can push back, and on doors that swing toward you, the hinge pins come out so the door lifts away. Before reaching for tools, it's worth simply asking the person inside to jiggle the knob or press the button again, since a sticky button sometimes releases on its own.

Why the door got locked

Let's fix it

1. Check on whoever is insideIf a person is inside, talk to them first. Ask them to push or turn the button on the inside knob, or to press the inside lever down, which unlocks many privacy levers automatically. Young children can often do this with simple directions. If no one answers, someone may be hurt, or a child is panicking, call 911 and keep talking through the door while you work on the steps below. If the room is empty, look at the outside knob or lever and figure out which kind of release it has.

2. Push the pinhole releaseStraighten a paper clip or use a thin Allen key, a small nail or the flat emergency key that came with the knob. Insert it straight into the hole in the center of the outside knob. Push gently until you feel a little resistance. Push firmly against that, and the lock should release; you may hear a click. Turn the knob while keeping light pressure. On some brands you push in and turn the tool or the knob slightly at the same time. Keep the tool straight so it stays on the release pin.

   • Nothing happens Try a stiffer tool, like a thin Allen key, and push harder. Wiggle it slightly to find the pin, and turn the knob while pushing.

3. Turn a slotted releaseIf the outside knob has a narrow slot instead of a hole, insert a small flat screwdriver, a butter knife tip or a coin edge into the slot. Turn it a quarter turn, usually either way until it stops, and the lock releases. Some slotted releases sit at the end of a short shaft inside the knob, so the tool may need to go in an inch or so. Turn the knob to open. If the slot is shallow or worn, a screwdriver that fits it snugly works better than a coin.

4. Slip a card past the latchNo release? Look at the gap between the door and the frame at the latch. This only works on a spring latch, where the angled side faces the way the door closes, and on a door that swings away from you. Use a flexible plastic card you don't mind damaging, like an old gift card, not a credit card. Slide it into the gap just above the latch, angle it down toward the latch, and push it in while you push and wiggle the door toward its hinges. When the card gets behind the angled face, it pushes the latch back, and the door opens. Stop if trim or a strip of molding covers the gap; prying it off damages the frame.

   • The card won't reach the latch There may be a stop molding covering the gap. Try the hinge pins (Step 5) or call a locksmith rather than prying.

5. Take the door off its hingesIf the door swings toward you, the hinge barrels are on your side. Have someone hold the door. Starting with the bottom hinge, put a nail or a thin screwdriver under the hinge pin's head from below and tap it upward with a hammer until you can pull the pin out. Then do the middle hinge and the top hinge last. With all pins out, pull the door away from the hinge side so the latch slides out of the strike, and set it aside. To rehang, line the hinge leaves up, drop the pins back in from the top and tap them down. See how to take a door off its hinges for more detail.

6. Fix a lock that keeps lockingOnce you're in, try the inside button and the release a few times with the door open. If the button sticks, the knob turns stiffly, or it locked by itself, a few puffs of dry PTFE lubricant into the latch and knob may help. If not, replace the privacy knob or lever: most install with two screws on the inside rose and a latch held by two screws on the door edge, and new privacy sets typically cost $15 to $30. If the door drags or the latch binds in the strike, see the guide for a door that sticks or won't latch. Keep the emergency key or a paper clip on the door frame above the door.

If it comes back

If the knob locks itself or the button stays in, the lock is worn. Replacing a privacy knob takes about 15 minutes. If the knob is loose or wobbles, see the guide for a loose door knob first.

If the door has to be pushed or lifted to latch, the latch may be binding in the strike, which also makes it harder to unlock. See the guide for a door that won't latch.

For a keyed lock on an exterior door, these methods don't apply. If a key broke off in it, see how to get a broken key out of a lock, and call a locksmith if you're locked out of the house.
