Why the spare key is the weak point

The key under the mat has been found for a hundred years.

A spare key hidden outside is the oldest arrangement in home security and the least private. Under the mat, over the frame, in the fake rock by the step: these are not hiding places, they are a short list that anyone who has ever locked themselves out already knows. The key is not the problem. Leaving it somewhere that can be guessed is.

A combination box changes what has to be shared. Instead of handing out metal that can be copied at any hardware counter, you give somebody four digits over the phone, and you take those digits back by changing them. Nobody keeps a key to your house because they helped out once, and nobody has to be home to let the plumber in.

For a parent living alone this is often the single most useful fitting on the house. If something happens inside, the people who need to reach them are not standing on the step deciding whether to break a window. That is a small thing on an ordinary day and an enormous one on the bad day.

You can take back a code. You cannot take back a copied key.

Where to put it

Findable if you describe it. Invisible if you don’t.

The instinct is to mount a key box right beside the front door, and that is the easiest place to describe on the phone. It is also the first place anyone glancing at the house will see it. A better spot is around the corner, beside a side door, or low on the wall behind a downpipe: somewhere you can direct a visitor to in one sentence, but that nobody notices in passing.

Then think about the code. Not the house number, not a birth year, not four digits that anyone standing at the door can read off the wall. Change it when a job finishes and the contractor no longer needs it. The value of a code is that it can be withdrawn, and most people never use that.

Setup

Fitted and coded in about ten minutes

1

Set your code first

Do it with the box in your hand, indoors, before it goes on the wall. Follow the reset sequence in the box, choose four digits, then open and close it a few times to be sure it takes.

2

Choose the spot

Somewhere a visitor can find from a one-sentence description but a passer-by would not notice. Beside a side door or around the corner of the house beats the front porch.

3

Drill and anchor

Mark the fixing holes, drill for the anchors supplied, and screw the body flat to the wall. Masonry, siding or a solid door frame all work as long as the box sits flush.

4

Load it and test it

Put the keys in, shut it, scramble the buttons, then open it again with the code. Have whoever will use it try it once while you are standing there.

It screws into a wall, which makes it a fixture rather than something you take with you. Mount it flush on a flat surface; a box that can be levered away from the wall is easier to work on than one that sits tight.
Who this is really for

The person who pays is often not the person who uses it

Plenty of these are bought by an adult child for a parent who lives alone, three hours away. That buyer is looking for something with no app to install, no bill in anyone’s name and no setup call on a Sunday, because the point is that it works without them. It is also the fitting that means a neighbour or a paramedic can get in through the door rather than the window.

Two halves of the same evening

The box lets the right person in. The alarm handles the rest.

A key box decides who gets in easily. It does nothing about the windows, which is where an uninvited visitor would go instead. A TremShield Vibration Alarm sticks to the glass and fires at 125dB at the first pry, before anyone is through. A six-pack is $99, so each alarm works out at $16.50, and that is the difference between a gift that is thoughtful and one that is used.

Good to know

Questions, answered calmly

This one takes several ordinary door keys or a key with a fob on it. Think of it as holding a small handful rather than a household’s whole key rack. If you need a spare car fob in there as well, check the fob’s thickness against the internal depth before you order.
It is built for outdoor mounting and a cover slides over the buttons to keep weather out, though no rating has been tested for it so we would not call it weatherproof. The bigger factor is placement: mount it out of casual view and set a code that is not the house number, and it stops being a target.
Yes. The code is set by you and can be reset whenever you want, which is the main advantage over a spare key. Change it when a contractor finishes a job or when someone no longer needs access, and their access is gone without changing a lock.
No. It is entirely mechanical: four push buttons, a code and a latch. There is nothing to charge, nothing to pair and no account to create, so there is nothing that can fail on the coldest morning of the year or when the Wi-Fi is down.
No, and it is not meant to be. A key lock box is an access device that lets the right person in without breaking anything. It is not a place to store valuables, and it does not protect the house. Pair it with an alarm on the windows if you want the house itself covered.
