Top pick for a home key

The top pick, when the key opens a home, is the KeySafe C500 Pro (B09JKFYWQ6) at £67.96. It carries 4.6 from 1,525 amazon.co.uk reviews. The listing shows Secured by Design. The maker datasheet cites LPS 1175 Issue 8 A5 and certificate 1062g: Category A tools, one person, for at least five minutes, when the box is fitted as it was tested. The lock is mechanical. There is no override key. The code opens in any order, each button once, which is not a phone-style PIN. The listing says up to six keys on an internal hook. Skip it on render or pebbledash, for a £7 to £15 dial, or if you need lit buttons. The weather attribute says not water resistant while the bullets claim a cover, so treat the cover as a shield rather than a seal. Height and who holds the code are on the carers page.

When the P500 Pro is the step-up

The KeySafe P500 Pro (B00OKS2NSA) is £93.95 and about 1.87 kg, with 4.5 from 833 reviews. The listing prints LPS 1175 Issue 8 A5 and Secured by Design, and the bullets add an anti-tamper plate over the code card. The lock is mechanical. There is no override key, and the anti-tamper screw needs a Torx T15 driver. Buy it when you want that plate and the A5 line on the same page. Both sit on the A5 line used here, so the extra spend is the plate, not a higher grade. A maker note described an earlier P500 as A3 and the Pro as A5. The capacity line says 5. Set the code in daylight: the legends are black on black.

The ark Tamo, without a grade

The ark Tamo (B0BW9F7ZH7) is £128.95 and 2.1 kg, with 4.5 from 144 reviews. The listing says a button may be used up to four times, and it claims over 9.7 million combinations. A review says the CR2032 powers the lights, not the lock. Two hooks and masonry screws that cut into brick are the extras reviewers mention. The secret is how many times each button is pressed, not a phone PIN. The Amazon listing prints neither A5 nor A10. A maker page has listed A10, and an earlier Secured by Design note said A5, so this page states neither code. Buy it for the lights and the counted presses.

Best value for a lockout spare

The best value is the Master Lock 5401EURD (B000JTIX3S) at £14.99, and only for a lockout spare. It is a resettable 4-digit dial, 442 g, with 4.6 from 27,113 reviews. Reviews say two ordinary house keys fit and bulky car fobs do not. The interior depth is about 3 cm. The listing states no Secured by Design and no LPS rating. The Mitoymia at £7.48, the Double Dragon at £7.49, and the GRIFEMA at £10.49 are the same job with no accreditation line. None of them is the answer if a council or insurer asked for a police-preferred specification. The Uniclife at £29.99 and the KornerBatl at £60.99 are indoor cabinets, not a carer’s way in.

Common questions

What is the top pick if the key opens your home?
The KeySafe C500 Pro at £67.96, when you can fit it to brick or concrete with the supplied screws. The listing shows Secured by Design, and the maker datasheet cites LPS 1175 Issue 8 A5. It is a poor match for a lockout-only budget.
Who should skip the C500 Pro?
Skip it on render or pebbledash, if you only want a £7 to £15 dial, if you need an indoor cabinet of hooks, or if you need lit buttons. The cover is a shield, not a seal, and there is no override key.
When is the P500 Pro the better buy?
When you want the anti-tamper plate over the code card and the A5 line printed on the amazon.co.uk listing, and the extra price over the C500 is acceptable. It is not a higher grade than the C500 on the line used here.
Is the ark Tamo the safest box in this set?
Not on the evidence in this batch. The Amazon page prints neither A5 nor A10, while other pages disagree. Buy it for lit multi-push buttons, not as a proven step above the C500.
What is the best value if you only want a lockout spare?
The Master Lock 5401EURD at £14.99. Ordinary house keys fit. Car fobs and a care specification do not. It has no accreditation on the listing.
Can you use the Master Lock 5401EURD for carers and call it police preferred?
No. The listing does not show Secured by Design or an LPS code. A council or insurer that asked for a police-preferred specification is asking for a different box.
Which box should an office skip in favour of a key cabinet?
Any outdoor wall box, including the C500. Tagged hooks belong on the Uniclife or the KornerBatl, indoors. Those cabinets are not a carer’s way in from the street.
