Smart Locks
Keypad, app or fingerprint entry — most retrofit onto your existing door
Pros
- No more spare keys under the mat — issue and revoke digital access instead
- Most models retrofit onto an existing door, so installation is usually straightforward
Cons
- Battery-dependent — check what backup access (physical key, USB emergency power) is included before relying on one as your only entry method
- Not every smart lock meets BS3621, which some insurers specifically look for — check before assuming a discount applies
About Smart Locks
Smart locks let you unlock a door with a keypad code, a smartphone app, a fingerprint, or a physical key as backup, and many let you issue temporary codes for guests, cleaners or tradespeople without handing over a physical key. Something worth knowing: most residential smart locks are designed as a retrofit that fits over your existing lock body (commonly a euro cylinder) rather than requiring a full door or lock replacement, which keeps installation quick — but always check compatibility with your specific door and existing lock type before buying, since not every smart lock fits every door. If home insurance recognition matters to you, check whether the underlying lock mechanism meets BS3621 (the British Standard insurers commonly reference for door locks) — not all smart locks do, even though they may still be perfectly secure day to day.

Frequently asked questions
What happens if a smart lock’s battery dies while I’m out?
Reputable models build in a backup — most keep a traditional key override, and some support external USB power to temporarily jump-start a flat battery from outside. Always confirm what backup method a specific model offers before you rely on it as your only way in.
Are you a security installer or manufacturer yourselves?
No — Home Security Innovations is an independent comparison and information service. We recommend checking any professional installer’s NSI or SSAIB accreditation directly before commissioning work.
Is all the pricing on this site guaranteed?
No — costs mentioned are typical ranges reported by trade and industry sources, not fixed quotes. Always get more than one itemised quote before committing, particularly for professionally installed systems.
What happens after I request a quote?
A partner installer or supplier reviews your details and gets in touch to discuss your property and requirements — there’s no obligation to proceed with any quote.
