Locks and Household Safety for Young Children

Let us say the honest part first. No lock replaces an adult paying attention. A latch can slow a toddler down, add a second step, or keep a door from swinging open in a draft, but a determined three year old will test every one of them. We think of hardware as a speed bump, not a wall.

With that in mind, the useful questions are narrow ones. Which door leads somewhere dangerous, like a road, a pool, a creek bank or a garage with tools? Which door should a small child be able to open from the inside if something goes wrong, such as a bathroom? Which keys are within reach when they should not be?

Walk through your home asking those three questions, room by room. You are not shopping yet. You are building a short list of doors that matter, and you will find that most of the house needs nothing at all.

Many parents find it helps to keep a simple running note on a phone: the doors that worry them, the ones they leave unlocked by habit, and any near misses. After a month, the pattern is usually clear, and the shopping list writes itself. It also gives a locksmith a precise description to work from, which saves time on site and keeps the advice honest.

Children grow in stages, and their reach grows with them. A toddler who cannot touch a deadbolt this month may stand on a stool next spring. Hardware placed high on the door, out of casual reach, buys time without a single extra gadget. A second bolt or a chain mounted well above head height is a plain way to add a barrier that adults can use with ease.

Keep in mind that the same height that stops a child can stop a grandparent or a guest in a wheelchair. If anyone in the home has limited reach, balance the two needs. Our guide on easier locks for aging parents at home covers the other side of that coin.

Re check the heights every few months. A bolt that was safely out of reach at one visit may be an easy stretch by the next, and a family often forgets how soon this happens until a small hand surprises them on a morning.

Watch for climbing as well. Children use furniture, laundry baskets and shoes to gain height. A bolt placed above reach today can be reached tomorrow if a chair sits beside the door. Move the chair, or the plan. That small habit of looking at what is near each door counts as much as the hardware on it.

The most important exterior door habit is one that has nothing to do with buying anything. Decide, as a family, where the keys live and who can open each door from the inside. In an emergency such as a fire, every adult must be able to leave shortly and without hunting for a key, so a double cylinder deadbolt that needs a key on both sides deserves a second look.

A single cylinder deadbolt, which turns by hand on the inside, is easier to leave through, but it can also be reached by a child. Some families add a secondary latch placed high on the door, so the main deadbolt stays easy for adults and the extra barrier lives out of a child's reach. Ask local fire safety resources what they recommend for your type of home, because rules and advice vary.

If you are replacing a lock, our lock installation service can talk through these trade offs on site. We would rather explain the options than push one, since the right answer depends on your doors, your yard and the ages of your children.

Some families prefer to teach older children how to leave the house safely in an emergency, and to practice it together. Knowing which way a bolt turns, and where the key hangs, makes a calm exit possible. Pick a time when nobody is rushing, and keep the lesson short and cheerful so it feels like a game and not a warning.

The sliding glass door is the favorite escape route of many small children. It opens with a light push, the latch is often at a handy height, and the glass invites them to lean. Many sliders have only a small hook latch that a child can flip and a stronger arm than they seem.

A secondary lock, such as a pin or a bar, placed high or low where a child does not naturally reach, adds a layer. A track bar that sits in the channel can stop the door from sliding even if the main latch is opened. Our page on sliding glass door locks goes through the main kinds.

Windows need the same thought, especially on upper floors. A window stop that limits how far the sash opens is a common choice, and it should still allow a way out for adults in an emergency. For older frames with tired hardware, see our notes on window locks for older homes.

Look at the screens too. A loose or bent window screen is no barrier, and children lean on them. Window guards and stops are meant to be easy for adults to release in a hurry, so look for ones with a clear release. When a window is stuck from paint or age, repair comes before any add on. A sound latch has to work first.

Inside the house, privacy locks are a different kind of tool. A bathroom lock gives a teenager or an adult privacy, but on a house with a toddler it can turn into a trap if the child locks themselves in. Most privacy locks have an emergency release on the outside, often a small slot or hole that a coin or thin tool can operate.

Know where that release is, and make sure every adult knows how to use it. Test it now, when nobody is upset, rather than during a scare. If a privacy lock has no outside release, or the release is stuck with paint, it can be repaired or swapped. See our guide to interior privacy locks for how these work.

Some families remove or reverse bedroom locks while children are small, and fit them back later. This is a personal choice, and we do not tell people how to run their home. If you want a lock turned so that it opens from the hallway side, that is a small job that a locksmith can do in a short visit.

Remember the coat closet and the pantry in homes where small children explore. Some adults add a latch on a utility closet that holds cleaning supplies or tools. These are surface mounted hardware items, simple to fit, and a locksmith can add them during any visit when other work is being done.

• Find the outside emergency release on every privacy lock in the house.
• Test each release with the tool that fits it and keep that tool nearby.
• Repair or replace any privacy lock whose release is painted shut.
• Decide as a household which interior doors should lock at all.

Keys are small, shiny and fun to chew. They also open doors. Hang the spare set well out of a child's reach, and keep the main set in a consistent place so adults do not leave them on a low table or in a bag on the floor. A dedicated hook above head height is a simple habit that prevents a lot of frantic searching.

Car keys deserve their own thought. A child who finds a fob can lock a vehicle with a button press or even start a push button car in some situations. Keep fobs out of reach, and see our notes on key fob basics if you want to understand what those buttons do.

If a child is ever locked inside a vehicle, call emergency services first, before anything else. Our page on a child or pet locked in a vehicle explains the order of steps, and why the locksmith call comes second.

Where a family lives in the North State, the yard is often large, and the danger spots are different from city to city. A shed with tools, a barn with machinery, a pond or a creek bank, a gate that opens on a road. Each one deserves a lock that a child cannot reach or work out.

Gates should latch on their own and sit high enough that a small hand cannot lift the catch. A latch with a spring return is better than a loose hook. Our guide to gate and fence latch security compares the common types, and the page on barn, shop and outbuilding locks covers padlock choices.

The door between the house and the garage matters too. A child who opens it can reach chemicals, tools and vehicles. Keep it latched and, where a lock fits your routine, keep it locked. Our garage entry door guide goes through the hardware.

Pets matter here, too. A gate that keeps a toddler in also keeps a dog in, and a gate that a dog can open is probably not safe for a child. Test your latch by pushing, pulling and shaking it, as a determined youngster would. If it lets go, tighten it up or replace the catch with a locking type.

Spare keys have a way of ending up in drawers where small hands explore. A lockbox mounted out of sight, or a spare kept with a trusted neighbor or relative, is safer than a drawer. If you use a lockbox, pick a code that is not a birthday and change it when someone no longer needs access.

Avoid hiding a key outside in the usual spots. A fake rock or a spot under a planter may be found by a child before it is found by anyone else, and it is not a good barrier against a stranger either. Our notes on hiding a key outside suggest better habits.

When a babysitter, a nanny or a relative begins to help regularly, think about whether they need a copy. A keypad lock lets you give a separate code that can be removed later. A key can be copied without your knowledge, and a rekey is the way to put everything back under one set.

If you rent, ask the owner before adding hardware that needs drilling. Rules differ from place to place, and a rental agreement may say what changes are allowed. Our notes on landlord and tenant lock questions list what to ask, and plenty of child safety add ons clamp on and leave no marks.

Smart locks appeal to families because they can show who opened the door and when. Some send an alert when a door unlocks, which is handy if an older child comes home from school. Others lock themselves after a set time, which cuts down on the morning dash where somebody forgets.

They are also another thing to charge, update and explain. Batteries die, apps change, and a power cut can complicate matters. Read our honest notes on smart locks, promises and practical limits before deciding. Keep a physical key way in as backup.

A smart lock does not make a door childproof. A child can still push a button, and an older one can learn a code by watching. Treat a code like a key: do not share it widely, and change it when circumstances shift.

After any change in the household, such as a new baby, a move or a visit from relatives, take ten minutes to walk the doors again. Things shift often with small children, and a plan that worked last season can need a small tweak. We are happy to be one of the calls you make when that walk turns up something puzzling.

With children, a lockout is rarely a simple inconvenience. A parent stuck outside while a child is inside, or the reverse, is a stressful situation that needs a calm plan. If a small child is alone inside and in danger, call emergency services first. Locksmiths come after.

For ordinary lockouts, have a plan before you need one. A trusted neighbor with a spare, a lockbox, or a keypad code can save a lot of worry. Our house lockout service is there at any hour when the plan fails, and the crew works to get you in without damaging the door.

Winter makes it harder. Cold hands, snow and short days all raise the stakes, so if you live in a mountain community consider our notes on preventing snow day lockouts. And if you want us to look at your doors, use the request form and tell us the ages of the children, the layout and your worries.
