What Are Smart Locks?
Smart locks replace or supplement your traditional door lock with an electronic mechanism that can be controlled via smartphone app, keypad code, fingerprint, or key card. The best models for UK homes retain a physical key backup for emergencies while adding digital convenience and control.
Benefits of Smart Locks
- Never get locked out — no physical key needed for entry
- Grant temporary access — send a one-time code to cleaners, tradespeople, or Airbnb guests without cutting a key
- Activity logs — know exactly when your door was locked or unlocked and by whom
- Remote control — lock or unlock your door from anywhere via your phone
- Auto-lock — the door locks itself after a set period, preventing the "did I lock the door?" worry
- No key copies in circulation — revoke digital access instantly rather than changing locks

What to Look for When Buying
- UK door compatibility — many smart locks are designed for US doors. Check it fits UK standard Euro cylinder or multipoint setups
- Physical key backup — essential for when batteries die or technology fails
- Security rating — look for Sold Secure, Secured by Design, or TS 007 ratings
- Battery life — most run on standard batteries lasting 6-12 months. Check before buying
- Weather resistance — UK weather demands IP44 rating minimum for exposed doors
- Insurance acceptance — check with your insurer before fitting. Not all accept smart locks
Smart Lock vs Anti-Snap Cylinder
If your budget only allows one upgrade, we recommend an anti-snap Euro cylinder first. It addresses the biggest real-world security threat (lock snapping) at a fraction of the cost. A smart lock adds convenience but doesn't necessarily improve physical security. Read our detailed comparison: Smart Locks vs Traditional Locks.
Professional Installation
While some smart locks are designed for DIY installation, professional fitting ensures correct alignment, proper battery setup, and integration with your existing security. Our lock replacement locksmiths install all major smart lock brands.
