Home security checklist: gates, grilles and keeping kids safe

This is general safety information, not a substitute for judgment about your own home, family, and specific circumstances. What works well for one household may not fit another.

Home security checklists usually focus on keeping people out. It’s worth spending equal attention on what happens for the people already inside, especially when there are children in the home, since the details that matter most aren’t always the ones that come to mind first.

Start with what’s reachable

Children explore locks the way they explore everything else: by watching and copying. A padlock or latch positioned at a height a curious four-year-old can reach, especially one they’ve watched a parent open dozens of times, isn’t unusual to see figured out eventually. This isn’t a reason to panic, but it’s worth a quick look at whether anything critical (a gate that opens onto a corridor, for instance) is at an easily reachable height without a good reason for it to be.

Cabinet and drawer locks matter here too if there’s anything inside you specifically don’t want a child accessing, but for entry doors and gates, the main concern is usually the opposite: making sure they can’t be opened by a child without adult knowledge, while still opening easily for an adult in an emergency.

Digital lock codes and kids

If you’ve got a digital lock, a shared PIN code is convenient for the household but comes with its own small risk: a code watched being entered a few times can sometimes be picked up by a child, just as easily as by anyone else nearby. A shuffle keypad, where the number positions change each time, reduces this specific risk since watching finger positions no longer reveals the code.

It’s also worth having a plan for what a child should do if they’re home and someone unexpected is at the door, separate from the lock hardware itself. That’s a conversation, not a device, but it matters more than which lock brand you choose.

Check	Why it matters
Gate or padlock height and reachability	Curious kids sometimes replicate what they’ve watched
Digital lock keypad type (standard vs shuffle)	Shuffle keypads reduce code-guessing from watched entries
Emergency exit speed from inside	Matters for every household member, especially in a fire
Who has keys or codes after contractors/cleaners visit	Old codes or keys left active are an easy fix to overlook

The emergency exit angle

Whatever locks you choose, the most important safety check is whether every adult and older child in the household can open the gate and door quickly from inside without needing to search for a key. This matters more than almost any other single factor, since a fire or other emergency is exactly the situation where a fumbled key or an unfamiliar mechanism costs real time.

After contractors, cleaners, or renovations

Anyone who’s had temporary access to your home, whether tradespeople, cleaners, or a previous tenant if you’ve just moved in, may have had a key or code at some point. It’s a reasonable precaution to change a shared code or rekey a lock if you’re not confident everything was accounted for afterward, particularly if it’s been a while since the code was last updated.

Balconies, service yards, and secondary doors

It’s easy to focus entirely on the front door and gate while overlooking secondary access points like a service yard door, a balcony gate, or a side entrance in a landed property. These often get lower-grade locks than the main entrance simply because they’re used less often, but for a household with young children, a secondary door that’s easy to unlatch is worth the same scrutiny as the front gate. A quick walk around every point of entry, thinking specifically about what a child could reach or figure out, catches gaps that a focus on the main door alone would miss.
