FAQ
What materials are these lockboxes made from?
These 10 litre safes are constructed primarily from robust steel, providing a durable and secure shell to protect your valuables. The locking mechanism itself is also metal for added strength against tampering.
How difficult is it to operate the key lock?
The key operated locking mechanism is designed for ease of use. It’s generally straightforward to open and close, however, it's crucial to retain your key securely and avoid using excessive force when locking or unlocking.
What size documents can I realistically store in a 10 litre capacity?
You could comfortably fit around 20-30 A4 sheets of paper within the 10-litre volume. However, consider the dimensions of your documents and any additional items you plan to include before purchasing.
Is the 1 year warranty cover damage caused by misuse?
The manufacturer’s warranty covers defects in materials and workmanship under normal use. Damage resulting from misuse, accidental damage or force majeure is typically not covered; please refer to Amazon's standard returns policy for details.
What kind of key comes with the lockbox?
Each lockbox includes a single, hardened steel key. It’s advisable to keep this key in a safe and secure location separate from the lockbox itself for added security.
Are these lockboxes suitable for outdoor use?
While designed for indoor use, they offer some protection against light weather exposure. However, prolonged exposure to rain or direct sunlight is not recommended, and you should ensure the lockbox remains dry.
What security level do these lockboxes provide?
These are a deterrent and provide a basic level of security suitable for protecting small valuables from opportunistic theft. They aren't designed to resist determined attacks; consider them as part of a broader home security plan.
Can I upgrade the locking mechanism later?
Unfortunately, the locking mechanisms on these 10 litre lockboxes are fixed and cannot be upgraded or replaced after purchase. You’ll need to rely on the manufacturer's warranty for any potential issues.
What is the weight of a standard 10 litre lockbox?
The average weight of a standard 10-litre lockbox, including the steel shell and locking mechanism, is approximately 3.5 - 4.5 kg. This can vary slightly depending on the specific model available on Amazon.
Does Amazon offer any guarantees beyond the manufacturer’s warranty?
Amazon offers standard returns terms for products sold on their platform. These generally allow you to return items within 30 days of purchase, provided they are unused and in their original packaging; please check Amazon's detailed conditions for full details.
