Use a Proven Lock on Your Self-Storage Unit: It Makes a Difference

Most self storage facilities have stringent security measures in place, including perimeter fencing, digital video monitoring and electronic gates with keypad access. Some have keyless systems that require only an app on your mobile phone to gain access and others offer “smart” units. Whether or not your facility is equipped with the latest in mobile or smart technology, you should purchase a high-quality padlock as an extra layer of protection for your valuables.

Before you purchase a lock for your self-storage unit, there are several things you need to consider.
  1. Depending on the security level of your storage facility, you’re probably trying to decide between a medium- and high-level quality lock. Remember the old adage, “you get what you pay for.” Don’t compromise the security of your belongings. Go with the best lock in your budget range, especially if you’re going to have your valuables in self-storage for a lengthy period of time.
  2. If it fits your needs, consider a shrouded shackle. They are more expensive, but harder to drill because of a protective covering on the shackle.
  3. Consider the size of your padlock and where you’ll be using it. You want it to fit; don’t buy an industrial-sized padlock for a small unit.
  4. If you’re considering a regular vs. a disc padlock, the disc padlock actually provides better security. These are considered by many to be the best locks for storage units because there is virtually no space to use bolt cutters.
  5. Be sure that your padlock is made of materials that will provide strength, hardness, longevity, durability, and resistance to corrosion. Common materials that will provide these qualities are steel, alloy steel, aluminum, carbides, and brass.
