My Buying Guide on ‘Door Knob Key Lock Box’

As a homeowner, I have always been concerned about the security of my house and the safety of my family. That’s why I decided to invest in a door knob key lock box. After researching and trying out different options, I have put together this buying guide to help you choose the best door knob key lock box for your needs.

What is a Door Knob Key Lock Box?

A door knob key lock box is a small, secure storage device that can be mounted on your doorknob or wall. It is used to store spare house keys, allowing you to grant access to your home when you are not around. These boxes are designed with a combination or key lock mechanism, ensuring that only authorized individuals have access to your keys.

Why do I need a Door Knob Key Lock Box?

Having a door knob key lock box provides convenience and peace of mind in case of an emergency or when you need someone to access your home while you are away. It eliminates the need for hiding spare keys under doormats, rocks or flower pots – which are easy targets for burglars.

Factors to Consider when Buying a Door Knob Key Lock Box

When shopping for a door knob key lock box, here are some factors to keep in mind:

1. Security

The primary purpose of a door knob key lock box is security. Look for one that has strong and durable materials such as metal alloy or hardened steel construction. The locking mechanism should also be reliable and difficult to pick.

2. Size and Capacity

Consider the size of your keys and how many you want to store in the lock box before making a purchase. Some models can hold multiple keys while others can only accommodate one or two.

3. Weatherproofing

If you plan on installing the lock box outdoors, make sure it is weatherproof and can withstand extreme temperatures and harsh weather conditions without compromising its integrity.

4. Ease of Installation

Choose a lock box that is easy to install, whether it’s through screwing onto your doorknob or wall mounting. Make sure it comes with all necessary hardware and instructions for installation.

Types of Door Knob Key Lock Boxes

There are two main types of door knob key lock boxes: combination and keyed.

a) Combination Lock Boxes

These require entering a unique code or pattern using dials or buttons on the box’s faceplate to unlock it. They offer convenience as there is no need for keys but make sure to choose one with good build quality as they tend to be more susceptible to wear and tear compared to keyed boxes.

b) Keyed Lock Boxes

These require using an actual physical key to unlock them, providing extra security against hackers who may try guessing your code or pattern on combination boxes. However, make sure not to lose the spare key as it defeats the purpose of having the lock box in the first place.

In Conclusion

Investing in a door knob key lock box is essential for any homeowner looking for added security and convenience. Consider factors such as security, size/capacity, weatherproofing, ease of installation, and type when choosing one that fits your needs best. With this buying guide in mind, you can now confidently purchase a door knob key lock box that will serve its purpose effectively.
