Let's get straight to it: a key lock box isn't supposed to be glamorous, it's merely supposed to provide you (or your family and friends) with access to your home when you can't. Out for brunch with the girls but your mom needs to pop by and grab something? Still at the gym but your boyfriend is waiting outside? There's no need to rush home anymore.

Saying that, it's more than worth investing in something that's safe and secure for peace of mind and for protection against potential break-ins. Whatever your budget and however many keys you have to hold, I've done the ~oh so~ fun job of doing some research on the best key lock boxes for your porch, doorstep, and more. So you can find one online, order it so that it arrives fast, and then fit it yourself — and within an hour. Then, all you need to do to give your nearest and dearest access is set a secure combination, pop the keys inside and let them know the code.

The portable lock handle could potentially be cut through

The Master Lock 5400EC Lock Box is a great large capacity, combination lock box that also benefits from being portable, so that you can attach it over a door knob. Which means you won't have to get your drill out, nor will you have to ask your landlord if you've got one. You can store five keys at one time within this lockbox, which is great if there are various areas of your home that tradespeople or visitors need access to, like your garage or backyard gate. It has a removable shackle for installation on doors within the house and on the exterior of your property. The protective weather covering also means that rain or shine, you'll have a lock box that you can depend on. We say to put it somewhere discreet and out of the way so people who are passing by won't be able to see it.

Things to consider when buying a key lock box

A key lock box should make your life easier, but can only do so if you pick the right box for your requirements. Before you click checkout on your favorite one, make sure to factor in capacity, so that all of your keys to various areas of your house are covered, as well as the type of lock you want. A combination lock is the most common, but a keypad or a dial lock are also great options to pose more of a challenge to potential troublemakers. You should also think about choosing a box that looks inconspicuous, to prevent it from becoming the target of a potential break-in.
