How Often Should You Rekey Your Home Locks? A Practical Guide

When was the last time you rekeyed your home locks? If you're like most homeowners in Orange County, the answer is probably never — or only when you moved in. That's a security gap that's easy to close, and inexpensive to fix.

What Does Rekeying Actually Mean?

Rekeying is not the same as replacing your locks. When a locksmith rekeys a lock, they open the cylinder and replace the small internal pins so that your old key no longer works. The lock hardware stays exactly the same — only the key combination changes. It's faster, cheaper, and just as effective as installing a new lock for most security purposes.

Replacing a lock entirely makes sense when the hardware is damaged, worn out, or you want to upgrade to a higher security grade. Otherwise, rekeying is the smarter choice.

When You Should Rekey Immediately

There are certain situations where waiting is not an option:

Moving Into a New Home

This is the single most important time to rekey. You have no idea how many copies of your key exist. The previous owner may have given keys to housekeepers, contractors, neighbors, dog walkers, family members, or a real estate agent's lockbox that was never fully accounted for. Rekey every exterior door before your first night in the home.

After a Break-In or Attempted Break-In

If your home was burglarized or someone attempted to enter, you may have damaged hardware that also needs replacement. But beyond that, if a key was stolen or copied during the incident, a rekey is essential. Don't wait.

Lost or Stolen Keys

If you've lost your house keys and can't account for where they ended up, treat it as a security event. The cost of rekeying — typically $25 to $40 per lock cylinder — is far less than the cost of a break-in.

Ending a Relationship or Changing Living Situations

If a partner, roommate, tenant, or family member with a key moves out on bad terms — or even good terms — rekey. People change, circumstances change, and you can't always predict future behavior.

After Any Service Professional Has Had Key Access

House cleaners, contractors, dog walkers, and other service providers often have temporary key access. Once that relationship ends, rekeying is the responsible security step — especially if keys weren't managed carefully.

How Often Should You Rekey Proactively?

Even without a triggering event, security professionals generally recommend rekeying your exterior locks every three to five years as a baseline. In high-turnover rental properties, rekeying between every tenant is non-negotiable and in many California cities it's considered best practice even if not legally mandated.

For homeowners in gated communities across Irvine, Newport Coast, or Anaheim Hills, the community entrance is handled by the HOA — but your individual front door is your responsibility entirely.

Rekeying vs. Smart Lock Upgrades

If you're already thinking about rekeying, it's worth considering whether this is a good time to upgrade to a smart lock instead. Keypad or Bluetooth deadbolts eliminate the key problem entirely for daily use. You can assign temporary codes to service providers and delete them remotely, monitor entry logs, and never worry about lost keys again.

Smart locks have come down significantly in price and can be installed in the same appointment as a rekeying service. Ask us about compatible options for your door hardware.
