## Key points

- Check door compatibility and insurance terms before buying.
- Look for recognised security certification.
- Smart locks may need replacing sooner than traditional locks.

## Summary

Smart locks let people enter their homes using a phone, code, fob or biometric features, and some can be operated remotely. Interest is growing in the UK, but buyers need to check that a lock suits their door and meets their insurer’s requirements, or installation could affect their cover.

There are three main types: units that replace the handle, retrofit devices fitted over an existing lock, and electronic cylinders that replace the mechanical one. Prices range from under £100 to more than £1,000, with a good-quality unit estimated at £200 to £250 before fitting; cited examples cost about £200 and £339. Buyers are advised to look for the BSI Kitemark or Sold Secure SS504 certification, check compatibility with UK door cylinders, and consider that smart locks may last only five to six years, compared with around 20 years for a traditional lock.
