Best Locks for Storage Units
Which locks work best for self storage units in Leander, TX?
While many self-storage facilities have security features like fencing with gated access, surveillance cameras, and bright lighting, a lock remains your last line of defense to prevent thieves from entering your storage unit and stealing your belongings. That’s why it’s so important to choose the right lock to keep your items safe – but which are the best locks for storage units?
At Pleasant Hill Storage, we recommend disc locks because they’re more difficult to cut or pry than other types of locks. For example, they feature hidden shackles that are hard for bolt cutters to access, especially compared to padlocks. Cylinder locks are also good options, but they don’t work with every type of storage unit door.
Here are the three most popular types of storage unit locks – disc, cylinder, and padlocks – and why most experts consider disc locks to be the most secure option.

Disc Locks
Disc locks are generally considered the best locks for storage units. They feature:
- Hidden shackles that are difficult to cut
- Designs that fit most storage unit doors and withstand weather
- Affordability
Many storage facilities recommend disc locks, and some – like Pleasant Hill Storage in Leander, TX – even provide disc locks to their tenants.


Cylinder Locks
Cylinder locks are also secure yet different from disc locks. They feature:
- No external bodies – they insert into door latches, so shackles are hidden and cannot be easily cut
- Designs that are flush with the doors, making them difficult to pry open
However, cylinder locks only work with compatible doors, so they’re not always an option.
Padlocks
Traditional padlocks are still popular choices, but we don’t recommend them because:
- Their exposed shackles are easy to access with bolt cutters
- The U-shaped shackles are also easier to pry
Even though they’re highly affordable and available in many styles – including keyed and combination locks – padlocks simply aren’t as secure as disc locks and cylinder locks.

Storage Unit Lock FAQs
What type of lock is best for my storage unit?
We recommend disc locks because they are difficult to cut or pry, so they’re more secure than many other types of storage unit locks.
How do thieves break into storage units?
Criminals use bolt cutters, pry tools, and lock-picking kits to break into storage units. They often target storage facilities that have weak security – no fences, poor lighting, no video surveillance, etc.
How can I secure my storage unit?
Start by choosing a storage facility that has strong security standards, such as gated access, 24/7 video surveillance, and overhead lighting. Most criminals will pass on secure facilities and instead target those with weak security.
Next, use a high-quality lock – we recommend disc locks – to ensure no one but you can access your storage unit.
