Amazon Basics Security Safe
Best BudgetPros
- Very affordable price point
- Compact size fits in drawers or cupboards
- Simple key lock operation
Cons
- No digital keypad option
- Thinner steel than premium models
The Amazon Basics Security Safe is the most affordable way to secure small valuables. It uses a traditional key lock with two keys included, and the steel body is sturdy enough for basic home use. The compact 3.5L size is ideal for storing cash, cards and small jewellery items discreetly.
Owner feedback highlights the value for money and simple setup. Some users note the key lock feels less secure than digital alternatives, but for the price it offers adequate protection against opportunistic theft. It works best when bolted down using the pre-drilled holes.
Burton Key Safe Box
Best Key StoragePros
- Weather-resistant design for outdoor use
- Easy to install with included screws
- Large enough for multiple keys
Cons
- Not suitable for valuables larger than keys
- Mechanical lock can be picked with skill
The Burton Key Safe Box is purpose-built for storing spare keys securely outside your home. It features a mechanical combination lock with a resettable code, and the zinc alloy body resists rust and weather damage. The 0.5L capacity holds several keys or a small key fob.
Owner reviews rate it highly for convenience and ease of installation. The combination dial is smooth and the shutter door protects the mechanism from rain. It is not designed for high-value items but is ideal for giving tradespeople or family members access to your property.
Master Lock 5900D
Best PortablePros
- Compact and lightweight for travel
- Digital keypad with backup key
- Cable loop for attaching to fixed objects
Cons
- Smaller capacity limits storage
- Not fire-resistant
The Master Lock 5900D is designed for portability, making it ideal for securing valuables in hotel rooms, gym lockers or car boots. It features a programmable digital keypad and a backup key, plus a steel cable loop that lets you attach it to a fixed object. The 2.5L capacity fits a wallet, phone and passport.
Owner reviews praise the sturdy build and ease of programming. The digital lock is responsive and the backup key provides peace of mind if the battery dies. It is not as secure as a bolted-down safe but offers excellent protection for items on the move.
Sentrysafe QAP1BE
Best Fire ProtectionPros
- 30-minute fire protection for documents
- Digital keypad with backup key
- Compact size fits in most spaces
Cons
- Thinner steel than non-fire rated models
- Fire rating is limited to 30 minutes
The Sentrysafe QAP1BE offers fire protection at an affordable price, making it a good choice for securing important documents like passports and birth certificates. It features a digital keypad with backup key and provides up to 30 minutes of fire resistance. The 4.0L capacity is enough for A4-sized papers and small valuables.
Owner reviews appreciate the fire rating at this price point, though some note the steel feels thinner than dedicated security safes. The digital lock is reliable and the included mounting hardware allows for wall or floor installation. It balances fire protection with basic security effectively.
What to check before buying a home safe under £100
Choosing a safe under £100 requires balancing security features with your specific needs. The most important factor is the lock type: digital keypads offer convenience and quick access, while key locks are simpler but require you to keep track of the key. For maximum security, look for safes with both a digital keypad and a backup key.
Steel thickness matters for physical security. Most safes in this price range use 1.2mm to 1.5mm steel, which is adequate for preventing casual theft but not for stopping determined burglars with tools. Always check if the safe has pre-drilled holes for bolting to a floor or wall, as this dramatically improves security.
Capacity is another key consideration. Smaller safes (2-4L) are fine for documents and jewellery, while larger models (5L+) can hold laptops or tablets. Fire resistance is rare under £100, but the Sentrysafe QAP1BE offers 30-minute protection if that is a priority.
Mistakes to avoid when buying a cheap safe
One common mistake is buying a safe that is too small for your needs. Measure your largest items before purchasing and add 20% extra space for future use. Another error is assuming all safes are fireproof - most budget safes offer no fire protection at all, so check the specifications carefully.
Do not rely on the safe's weight alone for security. Many buyers think a heavy safe is automatically secure, but without bolting it down, a thief can simply carry the whole unit away. Always use the mounting holes to secure the safe to a solid structure. Finally, avoid safes with poor owner reviews regarding lock reliability, as a jammed lock can leave you locked out of your own valuables.
