Storage Locks: A Guide

When you move your belongings into a self-storage unit, you want to be sure they will be safe for a long period of time. "Although most self-storage facility security systems are adequate (with fencing, video surveillance and keypad access) it is a good idea to invest in a good lock for your self-storage unit," says Ben Agothy of Storage Talk.1 "The peace of mind that comes with knowing your belongings are safe is worth any upfront investment."

The information below provides you with Uncle Bob's lock policy, an overview of types of locks and details about the locks we sell at our facilities.

Uncle Bob's Lock Policy

Lock is required
All customers are required to use a lock (one lock per access door) to secure their self-storage unit. This gives you the freedom to select your own lock and the assurance that your belongings are protected. Using your own lock means only you have access to your unit — none of our staff members have a key or a combination code. Please note, that some of our facilities require a cylinder lock for some storage units. For these spaces, there will be a one-time Lock Fee for the purchase of the cylinder lock.

Lost Key
If for some reason you lose your key, we can cut the lock off your unit for a fee. You'll then need to purchase another lock to secure your self-storage unit. To avoid this hassle, it's best to keep a spare in a secure place.

Delivery Acceptance
If you plan to have deliveries made to your storage unit without presence, Uncle Bob's will need a copy of your key and a written authorization to open your unit for shipments. Our staff will use the key or code ONLY to gain access for delivery acceptance.

Types of Locks: An Overview

An inexpensive lock is generally not worth it. It will be made with soft materials and poor shell casings, making it easy for someone to pry open or cut. We recommend (and sell) locks made from hardened steel and offering several additional security features.

U-shaped Shackle Padlock
This is a traditional lock you have probably used before. They can range from inexpensive and risky to expensive and secure. explains that a durable, secure padlock should cost around $15 and will have a thick, hardened metal shackle with a double lock at both the toe and the heel.2

Disc Locks
Disc locks are a type of padlock, but their round shape makes them more tamper resistant. Their smaller, curved shackles are harder to cut. Ryan Craft of says, "Disc locks are the best locks for storage units."2 Look for one with numerous pins inside the locking mechanism.

Cylinder Locks
This is the type of lock found on the front door of your home, and Kraft describes them as "the cutting edge of storage unit security." "For self-storage purposes, these locks do well as they cannot be cut by bolt cutters," says Agothy. But keep in mind that "only certain sizes will fit and changing the lock is fairly difficult if you do not have experience." Some storage spaces require this type of lock because the door does not have a hasp. It will have a slot made for the cylinder to fit into.
