Factors to Consider When Buying the Best Storage Unit Locks
1. Types of Locks for Storage Units
When looking for the best storage unit locks, it is crucial to understand the type of lock.
Cylinder locks usually fit inside an existing lock system on a storage unit. Since the lock mechanism is encased inside the storage unit, it is more secure than disc locks or padlocks.
A padlock has a compact square-shaped lock body with a U-shaped shackle between 3/8 of an inch and 5/16 of an inch in diameter. It usually opens with either a four-pin combination or a key.
Also known as round disks, they are similar to padlocks but have a disc shape with a curved shackle rather than a square with a U-shaped shackle. Since most of the shackle is usually covered by the lock body, this unit is more difficult to cut with bolt cutters or pry apart than a padlock.
2. Size and Material
When shopping, consider the size and material of the lock. Ensure that the lock's shackle fits snugly on the hasp or latch of the storage unit door. Also, the shackle should fit the latch as snugly as possible, leaving little to no space for an intruder to fit a pry bar between the shackle and the hasp. A 38-inch-diameter shackle with a 78-inch opening is ideal for most storage unit hasps.

On the other hand, consider the lock body. A high-quality lock will be crafted from robust, corrosion-resistant, hardened stainless steel materials. Besides, most locks have boron carbide shackles since the material usually resist cutting better than hardened steel.
3. Shrouded or Exposed shank
Padlocks and disc locks usually come in either shrouded or exposed shackle varieties.
A shrouded lock has a body that extends further around the shackle than a regular lock. This extended covering makes it challenging for intruders to access the shackle with a bolt cutter or a pry bar, making it more secure than a storage unit lock with an exposed shackle. However, these shrouded designs are more expensive than regular padlocks with exposed shackles.
We recommend investing in locks with shrouded shackles, as they are more secure.
4. Weather Resistance
When shopping for the best storage unit lock, consider its weather resistance. If the lock is exposed to the outdoors or severe weather, it's essential to ensure that it can withstand those circumstances. Weather-resistant storage unit locks are designed to withstand rain, humidity, snow, and extreme temperatures without compromising durability or functionality.
Keep in mind that even locks designed to withstand the elements may require regular maintenance, such as lubrication, to extend their lifespan and ensure smooth operation. Besides, regular maintenance will help your weather-resistant padlock remain effective and reliable, regardless of the weather conditions.
5. Security Level
It is crucial to consider the storage unit's location before choosing a lock. If the storage unit is in a low-crime neighborhood or is within a larger structure with a secure entrance monitored by cameras, then a simple padlock will be enough.

Storage units in areas with higher ceilings or doors accessible from the outside are more vulnerable to intruders, so they require a disc lock or padlock that can give a higher level of protection.
5 Steps You Must Take to Ensure the Safety of Your Storage Units
For various reasons, profitability has grown in the self-storage industry over the last decade. People seek storage units to create work or home space or keep unwanted stuff. It is a go-to solution for businesses and households to store excess inventories and belongings. Another typical use is during relocation, providing a temporary space for belongings. Storing items does not imply no longer wanting them. Hence, secure storage is imperative.
Maintaining storage units well is vital as it affects possessions. People tend to forget about them since constant visibility is not necessary, resulting in mess, dust, and potential mold. Such conditions can damage belongings and pose health risks. Hence, finding a safe storage facility is vital. So, what can you do to ensure the safety of your storage units? Here are some steps that will help in the process:
Image source: storable.com
Step 1: Opt for a Storage Unit with Multiple Layers of Protection.
When assessing the security measures of a facility, examine different aspects to ensure robust protection. The first line of defense is to look for a robust fence or gate surrounding the property. This perimeter barrier works as an initial security layer, effectively preventing unauthorized access or trespassing by individuals who do not have a tenancy or legitimate business at the location. Furthermore, electronic key codes for exit and entry provide an additional security layer, ensuring that only authorized personnel can access the premises.
Moreover, it is advisable to ascertain whether a designated employee is always available on the site. Of course, the facility does not necessarily need to be operational 24/7, but having an employee physically present, predominantly during non-operational hours, works as a powerful deterrent against potential miscreants. The mere presence of personnel discourages unauthorized individuals from attempting malicious activities on the premises.
Step 2: Environmental Protection is Vital
Ensuring the safety of your belongings in indoor storage is your primary responsibility. It necessitates confirming fortified and sealed units to avert potential environmental damage. Using climate-controlled storage can further reduce risks stemming from adverse weather conditions.
Without adequate protection, your possessions face the imminent peril of being subjected to several hazardous elements, such as corrosion, rust, fire, and floods. Any indications of furniture deterioration, such as splitting or cracking, metal discoloration, or mold and mildew emergence, warrant immediate inquiries regarding the feasibility of relocating to different facilities or units. By proactively addressing these concerns, you can reduce potential harm and ensure the long-term preservation of all your items.
Step 3: Invest in Quality Locks
Investing in superior-quality locks is paramount for securing your storage unit and guarding your valuable belongings. When selecting a lock for your storage unit, it is best to take security seriously and be proactive. Of course, some storage facilities may offer locks. However, we recommend taking matters into your own hands and picking a top-notch lock.

We recommend investing in disc locks. They are the most secure alternative for your storage units. Unlike traditional padlocks, disk locks cannot be cut off easily. Hence, they are a formidable deterrent against potential trespassing or break-ins. Moreover, if anyone tries to grind off a disc lock, it will create a noticeable noise, drawing attention to any unauthorized access attempt. This feature alone can dramatically lower the likelihood of intrusions and amplify the overall safety of your stored belongings.
Step 4: - Insurance is Important
You can increase the safety of your belongings with self-storage insurance. Of course, good locks and other security measures will offer the needed protection. However, unforeseen instances like theft, floods, or fire can still put your valuables at risk. Hence, never skimp on self-storage insurance.
Though some renter's or homeowner's insurance policies offer limited coverage for storage, you must always explore your options. You can find many reliable companies offering storage insurance plans. They make premium payments effortless, allowing you to combine the premium amount with the monthly rent.
Step 5: Maintain a Comprehensive Inventory of Your Belongings
Lastly, you must have a detailed record of all your belongings housed in the storage unit and a simple map to assist with locating items efficiently. Remember to note down the serial numbers of the electronic devices for reference. Form a detailed list, documenting the value of every item. It serves a dual purpose: 1) it comes in handy when furnishing information for potential insurance claims, and 2) it helps with organization.

This proactive approach helps you be well-prepared for unforeseen events like fires, theft, or any other incident that can damage your possessions. You can simplify the claim process and facilitate a smoother resolution with your insurance provider by maintaining a meticulous record of the stored items. Emphasize accuracy and precision while documenting, as it is imperative to safeguard your stored belongings effectively.
Frequently Asked Questions on the Best Storage Unit Locks
1. What type of lock is best for a storage unit?
Disc locks are the best type of lock used to secure storage units. They provide a wide variety of advantages. They are specifically designed to secure storage units and have proven extremely challenging to cut since the shape makes the hasp difficult to access.
2. What size padlock do I need for a storage unit?
A self-storage unit's most common padlock sizes are 1 3/4", 2", and 2 3/4". The door latch may not fit anything larger than a 2 3/4. Remember that the lock's size determines how easy it is to remove it.
3. Can I use a combination lock on a storage unit?
Some users say that combination locks are the best for storage units since there's nearly no space to use bolt cutters. However, we discourage using combination locks because, even though they may deter a lazy thief, they're easily snipped with a bolt cutter.
4. What is the difference between a storage unit and a locker?
A storage unit is best if you need somewhere to store bulky items like furniture, appliances, or business inventory. On the other hand, you can store documents or a few boxes in a storage locker.
