When to Replace
Six Situations That Need a Lock Replacement
Sometimes a repair isn’t the right answer. Here are the most common situations where replacing the lock is the safest, most cost-effective solution.
After a Break-In or Attempted Entry
A compromised lock — whether forced, drilled, or picked — should always be replaced, not repaired. The structural integrity of a breached lock can never be fully restored, and your insurer will almost certainly require it.
Your Lock Fails to Meet Insurance Standards
Most UK home insurance policies require at least a BS3621 five-lever mortice deadlock on external doors. If your current locks don’t comply, you may be invalidating your cover — replacement with an approved lock fixes this immediately.
The Lock Is Old, Worn, or Unreliable
Locks older than 10–15 years have often lost the precision needed to function securely. Repeated sticking or visible wear are signs that replacement — rather than continued repair — is the right long-term decision.
You’ve Lost Control of Who Has Keys
If keys have been lost, stolen, or distributed to previous tenants or contractors — and you can’t account for all copies — replacement is the only way to restore genuine security.
Upgrading to Anti-Snap or High-Security
Standard euro cylinders are vulnerable to lock snapping — a technique used in the majority of UK residential burglaries. Replacing with an anti-snap, anti-pick, anti-drill cylinder is one of the most impactful upgrades you can make.
Moving Into a New Property
No matter how trustworthy the previous occupants, you cannot know how many key copies exist. Replacing all external door locks on moving day is the single most effective security measure a new homeowner can take.
