When to change your locks

Five common reasons Cornwall homeowners change their locks:

  • Moving into a new home — you don't know who else has keys (previous owners, letting agents, builders, neighbours)
  • After a burglary or attempted break-in — insurance often requires it, and the locks may be compromised
  • Lost or stolen keys — same risk as moving in, but immediate
  • Holiday let changeover — between guests, especially if keys weren't returned
  • Upgrading to insurance-compliant locks (BS3621 5-lever mortice or TS007 3-star cylinders) — required by most home insurance policies

What it costs in Cornwall (2026):

  • Single euro cylinder replacement (UPVC door): from £80-£140
  • BS3621 5-lever mortice replacement (wooden door): from £120-£200
  • TS007 3-star anti-snap cylinder upgrade: from £100-£180
  • Multipoint lock mechanism replacement: from £180-£350
  • Full set of locks for a 3-bed house: from £300-£600

Ask the locksmith to fit British Standard compliant locks where your insurance requires them, and to show you the kitemark or star rating. Most Cornish locksmiths can fit a non-urgent lock change within 24-48 hours, or the same day for emergencies.

Three Ways to Find a Locksmith for Lock Changes in Cornwall

We’re an independent guide, not a locksmith. These are the honest options; if you’re locked out right now, use the first one.

2

Check Before You Hire

Ask the locksmith for ID when they arrive and a fixed price before they start. Ask whether they’re an MLA member, and be wary of national call-centre numbers posing as local firms. For lock changes, ask for BS3621 or TS007-rated parts if your insurance needs them.
