How Often Should You Replace Your Door Locks?

Door locks are one of the most important security features in any home or business, yet many people only think about them when something goes wrong. While there isn’t a strict expiry date for door locks, knowing when and why to replace them can significantly improve safety, convenience, and peace of mind.

Below, we explore the key situations where replacing your door locks is recommended, along with guidance on how often they should be reviewed.

When You Move into a New Property

Replacing your door locks should be one of the first things you do after moving into a new home or commercial premises. Even if the previous owner or tenant provides a full set of keys, you can never be certain how many copies exist or who may still have access. Changing the locks ensures complete control over entry points from day one and removes any uncertainty.

If Keys Are Lost, Stolen, or Unaccounted For

Lost or stolen keys present an immediate security risk. Even if you believe the chances of someone finding and using them are low, replacing the lock or cylinder is a sensible precaution. Acting quickly helps prevent unauthorised access and avoids the stress of potential break-ins.

For properties with shared access, such as flats or offices, this becomes even more important.

After a Break-In or Attempted Entry

Following a burglary or attempted break-in, replacing your locks is essential. Locks may appear functional on the surface but can suffer internal damage that compromises their strength. This is also an ideal time to upgrade to higher-security locks that offer improved resistance against forced entry.

When Locks Show Signs of Wear and Tear

Locks are mechanical devices and naturally wear down over time. Common warning signs include:

• Keys sticking or turning stiffly

• Difficulty locking or unlocking the door

• Loose handles or cylinders

• Keys snapping inside the lock
  

If any of these issues occur, replacing the lock can prevent complete failure and avoid being locked out unexpectedly.

Upgrading to Modern Security Standards

Older locks may no longer meet current insurance or security standards. Many modern locks offer enhanced protection, such as anti-snap, anti-drill, and anti-pick features. If your locks are more than a few years old or were installed before current standards were introduced, upgrading can significantly improve your property’s security.

This is particularly important for front doors, rental properties, and commercial premises.

After a Change in Occupancy

For landlords and business owners, replacing locks when tenants move out or staff leave is a best practice. It ensures former occupants no longer have access and helps maintain a secure environment for new tenants, employees, or customers.

How Often Should Locks Be Checked or Replaced?

While high-quality locks can last many years, it’s wise to review them every few years or whenever your circumstances change. Rather than waiting for a lock to fail, proactive replacement can save time, money, and stress in the long run.

Professional Advice Makes the Difference

Not all locks need full replacement. In some cases, changing the cylinder is enough. A professional locksmith can assess your existing locks and recommend the most cost-effective and secure solution based on your needs.
