When Should You Change Your Locks?

Knowing when to replace your locks is crucial for maintaining property security. Here are the most common situations where lock changing is essential:

Moving Into a New Property

This should be your priority. Previous owners, tenants, estate agents, builders, cleaners, and tradespeople may all have kept spare keys. You simply can’t know for certain who has access. Having your locks changed immediately ensures that only you and your family have the keys to your new home.

Lost or Stolen Keys

If your keys have gone missing, don’t wait and hope they turn up. Acting quickly prevents potential break-ins. Our emergency locksmiths can change your locks the same day, restoring your security before lost keys can be misused.

After a Break-In or Burglary Attempt

Burglars often damage locks during forced entry attempts. We provide rapid-response lock replacements after break-ins, securing your property quickly and installing upgraded anti-snap locks to prevent future attacks.

Relationship Breakdown or Tenant Change

When relationships end, or tenants move out, you need certainty about who has access to your property. Changing locks protects you legally and practically, ensuring former partners or tenants cannot enter without permission.

Upgrading to High-Security Locks

Older locks may not meet modern security standards. Upgrading to anti-snap euro cylinders, British Standard locks, or restricted key systems significantly improves protection against common burglary methods like lock snapping, picking, and bumping.

Worn, Stiff, or Faulty Locks

Locks that stick, jam, or require excessive force are warning signs of wear. Replacing them before they fail prevents frustrating lockouts and potential security vulnerabilities.
