Best Spare Key Rock

Updated November 3, 2023

Have you ever been locked out of your house? What did you do? Did you have a spare key? If this has happened before, you know how frustrating that can be when you don’t have a spare key.

Keeping a spare key outside is a great way to make sure that never happens. However, just sticking a key under the doormat is never a good idea no matter how safe you think your neighborhood is.  This is going to be the first place a potential burglar looks.

Luckily, some options are safe and secure that won’t keep you locked out. Fake rocks are an excellent way to store spare keys in case you need them in a pinch. Fake rocks blend in with the real rocks around the landscaping, shrubs, or grass in your yard, perfect for keeping nearby your porch or by the backdoor.

We have compiled a list of the best spare key rocks available online to help you narrow down your options.

What To Look For in a Spare Key Rock

Having a spare key rock is a great solution for hiding a spare key on your property. This option is extremely popular for homeowners and realtors. Some homeowners also use a spare key rock for their home cleaning service or anyone that may need access to their home when they are away. On a fun note, these are also used for Geocaching! Let’s talk about some of the key features that you should look for in a spare key rock.

Realistic Design

The most important part of a good spare key rock is that it is designed to blend into your landscaping without giving away your secret. Good rock is going to look realistic and not stick out when placed in your yard or garden. You want it to be disguised without drawing unwanted attention to unsuspecting passersby. Most rocks are made out of polyresin to give it weight and a realistic look and feel.

Match Your Landscaping

When shopping for a spare key rock, look for one that blends with your landscaping. For example, if you have larger river rocks in your flower beds, you want to match them with those. You don’t want to purchase a fake rock that sticks out.

Pay Attention to the Bottom Cover

Some key holds have a white or plastic cover on the bottom to hold the key. This might be something you don’t want because if flipped over, it’s a dead giveaway. Instead, look for rocks that have a cover in the same material and design as the rock itself.

Are You Hiding More Than One Key?

Do you plan on hiding more than one key at a time? If so, you’ll want to find a spare key rock that has a larger inner compartment. There are varying sizes. So, if you need to hide more than one key or a keyring, keep that in mind.

Worried about Rusting or Moisture?

Moisture can get inside your spare key rock which can lead to rusting. You want to look for one that is moisture-proof and humidity-resistant to withstand the elements. Some rocks come with a baggie to place the key in. If the one you purchase doesn’t, you may want to wrap your key in a bag to prevent any type of mold or moisture issues.

Hide the Rock in Plain Sight

Be sure to hide the rock in an area where you won’t forget where to find it. These key holders can look so realistic that some people can’t recall where they put it among the real ones!  Once you establish a good hiding place, make sure to alert your family members and explain that they shouldn’t share that information with anyone else.

Don’t make the hiding place obvious. Potential burglars understand and know where some of the most popular hiding places are. They also know how to identify these key holders. Keep in mind that most burglars will not spend a ton of time rummaging around because they want to get in as quickly as possible. So, hiding your spare key rock in an unusual place that blends in is the best option.

There is something for everyone on our list of the best spare key rocks that are sure to meet your needs. Take all of our tips into consideration so that you can make the best choice when shopping online.
