The Ultimate Buying Guide for Key Lock Boxes

A key lock box is a simple but very important tool. It lets you safely store spare keys outside your home or business. This guide helps you pick the best one for your needs.

Key Features to Look For

When shopping for a key lock box, certain features make a big difference in how safe and easy it is to use.

1. Locking Mechanism Type

  • Combination Locks: These use numbers. They are easy to change. Make sure the dials turn smoothly.
  • Keyed Locks: These use a physical key. They are very secure but you need to keep the spare key safe.
  • Electronic/Digital Locks: These use batteries and a keypad. They allow for quick code entry. Check the battery life.

2. Capacity and Size

Think about how many keys you need to store. Some boxes hold just one or two keys. Others hold many keys and even small items like access cards. Measure the space where you plan to mount the box too.

3. Mounting Options

Most boxes need to be fixed to a wall or solid surface. Look for boxes that come with strong screws and mounting hardware. Some models can be hung over a railing or pipe.

Important Materials That Matter

The material of the lock box directly affects how well it resists weather and attack.

Metal Matters Most

  • Zinc Alloy: This is common. It offers decent protection against rust.
  • Stainless Steel: This is the best choice for outdoor use. It resists rust very well.
  • Aluminum: It is lightweight and resists corrosion. It is often used in less harsh environments.

A thick metal body offers better protection. Thin metal gets pried open easily.

Factors That Improve or Reduce Quality

Not all lock boxes perform the same. Quality shines through in the details.

Quality Boosters

  • Weatherproofing: Look for rubber gaskets or tight seals. These keep rain and dust out.
  • Hinges and Shrouds: Strong hinges last longer. A protective cover (shroud) over the keyhole or keypad hides it from view and tampering.
  • Resettable Codes: High-quality combination boxes let you change the code often.

Quality Reducers

Cheap plastic parts break quickly. Poorly finished metal rusts fast. If the manufacturer cuts corners on the thickness of the metal, burglars can easily smash the box open.

User Experience and Use Cases

How you plan to use the box shapes your best choice.

Real Estate and Rentals

Realtors often use lock boxes for showing homes. They need quick, easy access, often requiring a temporary code that expires. Ease of code entry is key here.

Home Emergency Access

Families often keep a spare key for emergencies (like a lost house key or for visiting neighbors). The code must be easy for trusted people to remember, but hard for strangers to guess. Make sure you can open it quickly if you are locked out on a dark night.

Business Use

Small businesses might use a box to hold keys for a supply closet or gate access. Durability and high security are the top priorities for these settings.

Frequently Asked Questions (FAQ)

Q: What is the best way to secure the lock box?

A: You should always bolt the box securely to a solid surface like a brick wall or a thick wooden post. Never mount it where it is easily visible from the street.

Q: How often should I change the code?

A: If you share the code with many people, change it every few months. If only one or two trusted people know it, changing it once a year is usually fine.

Q: Can a strong magnet open a lock box?

A: Most modern, high-quality metal lock boxes are protected against common magnets. However, very powerful industrial magnets could potentially interfere with electronic models.

Q: What if I forget the combination?

A: If you have a mechanical combination box, you might need to use a master key (if provided) or drill the lock out. This is why writing down the code somewhere extremely safe is important.

Q: Are small lock boxes safe enough?

A: Small boxes are easier to hide. However, they often have less metal, making them easier to pry open or carry away. Bigger, heavier boxes are generally safer.

Q: Should I get a weatherproof box?

A: Yes, always. Even if you plan to place the box under an overhang, rain blows sideways. Weatherproofing prevents internal parts from rusting and jamming.

Q: What is the difference between a portable and a fixed lock box?

A: A fixed box is screwed down permanently. A portable box usually has a strong cable or shackle that lets you temporarily attach it to a railing or pipe, making it movable.

Q: How heavy should a good lock box be?

A: Heavier is usually better. Weight often means thicker metal walls, which makes forced entry much harder for thieves.

Q: Do I need insurance if I use a key lock box?

A: A lock box helps provide access, but it does not replace home insurance. Check with your insurance provider; some might require you to use a specific type of high-security box for certain coverage.

Q: What is the easiest type of lock for seniors?

A: Large-dial combination locks are often best for seniors because the numbers are easy to see and turn, avoiding the need for small keys or complex digital keypads.
