Why the right padlock matters
A standard padlock might not be enough to keep your unit secure. Weak locks are easy to break, rust in poor conditions, or fail under pressure. Worse, some insurers will not cover a claim if the locking system does not meet their guidelines.
Before choosing a storage padlock, ask yourself these questions:
- What are you storing?
- Who needs access?
- Is your unit indoors or outdoors?
- What level of security do you need?
- Does it fit the locking clasp and latch of your unit?
What makes a padlock secure?
When comparing padlocks, a few key features make the biggest difference to your security. Here's what to look for.
Shackle security
A good padlock will have a reinforced locking bar that resists bolt cutters. Some models include shrouded or hidden shackles for extra security against forced access.
Material and build
Look for hardened steel, stainless components, or laminated steel bodies with a hardened steel shackle.
These offer higher durability and weather resistance. This is especially important for outdoor storage and sheds.
Locking mechanism
Options include keyed locks, combination locks, cylinder locks, and electronic locks. Each offers a different balance of ease of use and security.
Electronic locks can be ideal where digital access and backup features are useful.
Insurance compatibility
Check if your insurer or storage facility has minimum standards. Many require disc locks or approved cylinder lock designs for full security.
Types of padlocks for storage units
Each type of padlock serves a different purpose. Below are the most popular options for self storage units.
Disc locks
These are the most common locks used in self storage units. Their curved design hides the shackle, making them extremely hard to cut with bolt cutters or compromise through other common methods. Disc locks also offer strong internal mechanisms that resist picking and drilling.
Best for: general storage use, indoor or outdoor units
Strengths: high security, good weather resistance, strong internal mechanism
*Available at our online box shop for £12.50
Cylinder locks
A cylinder lock uses a rotating mechanism similar to those found in door locks. The design can include anti-pick pins and solid casing.
Best for: units storing high-value items or important documents
Strengths: discreet design, tight fit, often approved for insurance purposes
Laminated steel locks
Built from stacked steel layers, these locks offer good resistance to force while keeping costs down. While not as strong as a disc lock, they perform well in indoor conditions.
Best for: short-term indoor storage,
Strengths: budget-friendly, light, solid against general wear
*Available at our online box shop for £7.50
Brass combination locks
Combination locks use a code instead of a key. This can be ideal for shared units or users prone to losing keys. The downside is a trade-off in security. Unless using for a HOLD unit (with 24/7 CCTV and advanced security measures), be wary of securing valuables with this.
Best for: temporary storage, shared family use
Strengths: no key to manage, designed for smooth operation and available in weatherproof designs
*Available at our online box shop for £14.00
Armoured steel locks
These strong padlocks resist interference and cutting attempts. Offering enhanced protection, they are typically made with a reinforced body.
Best for: outdoor, long-term, or high-value items
Strengths: excellent durability, best for resisting physical force
*Available at our online box shop for £32.00
How to choose the best padlock for your storage unit
Step 1: Consider your risk
If you are storing valuable items, invest in a higher security level. For day-to-day needs or short-term stays, a simple keyed padlock may suffice.
Step 2: Match the lock to the environment
Units in extreme temperatures or exposed areas need the proper resistance. Some locks come with protective covers to shield the shackle and body from rust or dirt.
Step 3: Think about accessibility
Are you sharing your unit with family or staff? If yes, go for a combination lock or electronic padlock to avoid multiple keys. If not, keyed locks offer better security.
Step 4: Confirm the fit
Make sure the padlock fits the latch securely. A loose fit leaves space for tools to get in and tamper with the lock. Choosing the right padlock helps prevent security concerns, even in traditional ones like cylinder designs.
Final advice
Choose a padlock that is strong, simple to use, and reliable. Whether keeping less valuable items or equipment, choosing the best padlock helps ensure the right level of protection. You need a padlock that fits well, provides the right level of security, and is accessible.
