How Often Should You Change Your Home’s Locks?

There’s no fixed timeline for changing your home’s locks, but you should update them anytime security may be compromised, such as after moving, losing keys, or experiencing a break-in. If your locks are functioning properly and key control hasn’t been lost, routine replacement isn’t typically necessary.

Instead of focusing on time alone, it’s better to evaluate specific life events and signs of wear.

Change Your Locks After Moving Into a New Home

One of the most important times to update your locks is immediately after purchasing or moving into a home.

You may not know how many copies of the existing keys are in circulation. Previous access could include:

• Former homeowners
• Contractors
• Real estate agents
• Neighbors

According to the U.S. Census Bureau data, millions of Americans move into new homes each year, making lock rekeying one of the most common residential locksmith services.

In many cases, rekeying, rather than full replacement, is sufficient.

Change or Rekey After Losing a Key

If your house key is lost and cannot be recovered, updating your locks may help restore security.

You should act more quickly if:

• The key was lost near your home
• Your address was attached to the key
• The key may have been stolen

“If there’s any uncertainty about who might have access, rekeying restores control.” - KeyMe Locksmiths

Rekeying changes the internal pins so old keys no longer work.

Replace Locks After a Break-In

If a break-in occurred, or was attempted, lock replacement is often recommended.

According to FBI Uniform Crime Reporting data, a significant percentage of residential burglaries involve unlawful entry through doors.

Even if the lock appears functional, internal damage may affect reliability.

Change Locks When They Show Signs of Wear

Locks don’t last forever. Over time, components can wear down due to daily use and environmental exposure.

Warning signs include:

• Difficulty turning the key
• Loose or spinning lock cylinders
• Rust or visible corrosion
• Keys getting stuck

The median age of owner-occupied homes in the U.S. exceeds 40 years, meaning many locks experience decades of wear.

If your locks feel unreliable, replacement may improve performance and security.

Upgrade Locks for Modern Security

You may also choose to replace locks when upgrading to:

• High-security deadbolts
• Smart locks
• Keyless entry systems
• Reinforced strike plates

While not required on a schedule, upgrading can improve convenience and access control.

Rekeying vs. Replacing: Which Do You Need?

A professional evaluation can help determine the best option.

Frequently Asked Questions

Should I change my locks every few years?

Not necessarily. Locks should be updated based on security events or wear—not just time.

Is rekeying as secure as replacing?

Rekeying restores key control but does not upgrade hardware strength.

How do I know if my locks are outdated?

If they lack reinforced strike plates or show visible wear, replacement may be beneficial.

Can I rekey instead of replacing after losing a key?

In many cases, yes, if the hardware is still in good condition.

What’s the most important time to change locks?

Immediately after moving into a new home or after a security compromise.

Focus on Security Events, Not Just Time

There’s no universal schedule for changing home locks. Instead, focus on moments when key control may be compromised or when hardware shows signs of wear. Taking action during these events helps maintain consistent home security.
