Storage Security: Your Lock Makes a Difference

July 28, 2020 Security / Self Storage

These days, 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. If your unit isn’t equipped with the latest in mobile or smart technology, you should consider purchasing a high-quality padlock.

Before you purchase a lock, there are several things you need to consider.

  • Depending on the security level of your storage facility, you’re probably trying to decide between a medium- and high-level quality lock. Don’t compromise the security of your belongings. Go with the best lock in your budget range, especially if you’re going to be storing for a lengthy period of time. 
  • If possible, consider a shrouded shackle. They are more expensive, but harder to drill because of a protective covering on the shackle.
  • Consider the size of your padlock and where you’ll be using it. You want it to fit, and you don’t want to buy an industrial-sized padlock for a small unit.
  • If you’re considering a regular vs. a disc padlock, the disc padlock actually provides better security. Some say these are the best locks for storage units because there is virtually no space to use bolt cutters.
  • A combination lock is better used for you kid’s school locker. They may deter a lazy thief; but, even for an amateur, they are easily snipped with a bolt cutter.
  • 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.
