FAQ
What is the locking mechanism like?
These safes utilise a robust 3-point locking system, offering reliable protection against tampering. The keys are durable and designed to withstand repeated use.
Is it fire resistant?
While these safes offer a degree of protection against heat, they aren't officially fire rated for prolonged exposure. They can provide short-term protection during minor incidents but shouldn’t be relied upon in a full-scale fire.
How secure are the locks?
The locks are tested to resist forced entry attempts, providing a significant deterrent against burglary. Regular key changing is always recommended for enhanced security.
What materials are the safes made from?
Each safe is constructed primarily from hardened steel, known for its strength and resistance to impact and cutting. The locking components are also manufactured from high-quality steel.
Are they suitable for storing documents?
Yes, these safes are well-suited for storing important documents like passports, birth certificates, and insurance policies, keeping them secure and organised.
How easy are they to install?
These safes are designed for straightforward placement. They do not require any drilling or permanent installation; simply find a suitable location within your home.
What size are the safes?
Each safe measures approximately 30cm (W) x 25cm (D) x 18cm (H). The dimensions ensure they can be placed comfortably on most surfaces.
Are the keys duplicated?
We recommend against duplicating the keys to maintain security. If a key is lost, you'll need to contact the manufacturer for a replacement.
What’s the warranty like?
The standard Amazon UK warranty applies to these safes, covering defects in materials and workmanship. Please refer to Amazon's returns policy for details on claiming a refund or replacement.
Can I upgrade the locks later?
No, the locking mechanisms are permanently fitted as part of the safe’s design. This ensures the integrity of the security system and prevents potential tampering.
