Storage units allow individuals and families to have a convenient means of temporarily storing personal belongings when moving between homes. Some people rent storage units to de-clutter their home, or to permanently store possessions.

Are you an individual that likes to set up at trade shows, flea markets, or antique sales? Storage units that help protect the items between events or sales offer vendors easy access to their items.

No matter the reason that you use a storage unit, properly securing the unit with a proper lock is of utmost importance. Knowing which type of lock is ideal for your unit is important before you purchase a lock for one or more storage units.

How Do I Know Which Type of Storage Unit Lock is the Right Choice for Me?

How do you know which type of lock is the ideal lock for your storage unit? Choosing the right type of lock from the many different types of locks for storage units likely prevents your storage unit from being among the list of vandalized units on the next news report of a break-in at a storage unit facility.

You also want to make sure that you choose a lock that offers easy access for yourself. You want to choose a lock that does not result in the embarrassment of having to ask someone else to open the lock for you.

Cost Considerations of Storage Unit Locks

Do you have multiple storage units? Do not make the cost of a high-quality lock an issue. Look for a high-quality lock for each storage unit, rather than skimping on the cost. Skimping on the cost potentially means that you also get a lower quality storage unit lock.

A Store-N-Lock article suggests that you speak with a storage unit employee or manager before purchasing a lock so that you know if there are any restrictions on the type of lock allowed on their storage units. Some facilities possibly require that you purchase only a certain type of lock.

If you place a different type of lock on a storage unit against the rules, you will likely receive a call to replace the unapproved lock with the required lock. Save money by purchasing the required type of lock.

Are There Special Considerations When Choosing Different Types of Locks for Storage Units?

Consider the storage facility and the individual storage unit before you make your storage unit lock purchase. Is your storage unit located inside? Do you have an outside unit or a combination of inside and outside storage units?

These are all important considerations when determining the right type of lock for storage units. If you have an outside storage unit, the lock is exposed to the elements. Storage Front explains that outdoor storage units are exposed to rain, freezing temperatures, and extremely hot temperatures.

Weather conditions affect the performance and durability of some locks placed on storage units. Choosing a lock that is made of brass helps to protect against the changes in weather conditions.

Another factor to consider if you have an outside storage unit is the vulnerability of your unit. Do not automatically assume that just because the facility has iron gates or other barriers that the outside storage units at the facility are burglar-proof or tamper-proof.

There are many examples of storage units being broken into at storage facilities with high gates or other protections. Can you or a family member climb over a gate or bushes?

Imagine how easy it is for a determined thief to do the same thing. Choose a tamper-resistant lock to make breaking into your storage unit a difficult task for would-be storage facility burglars.

Durable locks help protect valuables. Some people store out-of-season clothes or sporting equipment, while other people store valuable antiques or household belongings.

Read the packaging of storage unit locks to consider the security features of the lock. The security features of the lock are much more important than a fancy look.
