Master Lock 5-Key Combination Safe Black/Silver 5401D

The 5401D combination lock box offers a secure storage spot for spare household or business keys. Built to mount permanently to a wall or fixed structure, it solves the problem of hiding loose keys outside while giving authorized guests, workers, or family members easy access.

Inside, the lock box provides a 7.3 cubic inch storage volume, measuring 3-1/4 inches high by 2-1/4 inches wide and 1 inch deep. This compartment holds up to five standard keys. Access is managed through a four-digit combination lock that you can set yourself, allowing you to choose and reset your own personalized code whenever needed.

The outer housing measures 4-3/4 inches high, 3-1/4 inches wide, and 1-1/2 inches deep. It features a durable metal body suitable for indoor or outdoor installation. To help keep the four numbered dials operating smoothly in outdoor environments, a built-in shutter door slides over the front interface to shield the dials from weather.

Because the safe is designed specifically for wall installation, you will need a solid mounting surface. The 1-inch interior depth also means it is tailored for standard flat keys rather than oversized items, large key rings, or bulky electronic fobs.

Verdict: This wall-mounted combination safe is an effective, straightforward solution for anyone who needs to store up to five standard keys securely. It is ideal for property owners who want reliable, keyless access control without complex electronics.
