Key Safe Installation Guide UK¶

How to choose, install, and use a key safe securely for your UK home.

Choosing the Right Key Safe¶

The key safe market in the UK has grown 40 % since 2020, driven by ageing-in-place and Airbnb lets. The Master Lock 5401D (£39.99) is the most popular model - Secured by Design approved with a 10,000-combination dial. Supra C500 Secure (£79.99) is police-recommended for its anti-pry design. The Brisant Secure KeySafe (£89.99) offers biometric fingerprint access. All should meet the TS 009 standard for thief resistance. Avoid cheap safes under £20 - Which? testing found they can be opened with a screwdriver in under 30 seconds.

Installation Best Practices¶

Mount the key safe at least 1.5 m from the door and not visible from the street. Screw directly into brick or concrete using the supplied masonry anchors - never into plastic facias or wooden frames. Height should be accessible but not obvious: 1.4 - 1.6 m is the sweet spot. Register the safe's serial number with the manufacturer for replacement keys. Change the code every six months. The Home Office recommends informing your home insurer - some (e.g., Saga, Aviva) offer 5 % discounts for TS 009-approved key safes.
