Rekey vs Replace Locks: A Los Angeles Homeowner's Guide

Whether you've just moved into a new home, lost a key, or want to upgrade your security, you're probably wondering: should I rekey or replace my locks? The answer depends on your situation, your locks, and your budget. This guide for Los Angeles homeowners breaks it down.

What Is Rekeying?

Rekeying is the process of changing the internal pins inside a lock cylinder so that old keys no longer work. You get a brand-new set of keys, but the lock hardware itself stays the same.

When to Rekey

• You just moved in — you never know who still has a copy of the old keys.
• You lost a key — rekeying ensures the lost key can't be used.
• A roommate or tenant moved out — revoke their access instantly.
• Your locks are in good condition — rekeying is the cost-effective choice.

Rekeying Cost in Los Angeles

Rekeying typically costs Call for pricing per lock cylinder, plus a service call fee. For a standard home with 2–4 locks, the total is usually Call for pricing.

What Is Lock Replacement?

Lock replacement means removing the entire lock and installing a new one. This is necessary when your locks are damaged, outdated, or you want to upgrade to a different brand or style.

When to Replace Locks

• Your locks are old or damaged — worn-out locks are less secure and harder to use.
• You want to upgrade security — switch to high-security or smart locks.
• You have mismatched locks — replace them all with one brand for a master key system.
• Your locks are low quality — builder-grade locks from construction are easily defeated.

Lock Replacement Cost in Los Angeles

What Should Los Angeles Homeowners Choose?

Just Moved In? Rekey.

This is the #1 reason to rekey. You never know how many copies of the old keys exist. Rekeying is fast, affordable, and gives you peace of mind that only you have access.

Lost a Key? Rekey.

If your locks are in good condition, rekeying is the quickest way to make the lost key useless. It's far cheaper than replacing all your locks.

Upgrading Security? Replace.

If you want smart locks, high-security deadbolts, or a master key system, replacement is the way to go. You'll get better hardware and the security features you want.

Old or Damaged Locks? Replace.

If your locks are sticking, hard to turn, or visibly worn, rekeying won't fix the mechanical issues. Replacing them ensures reliable operation and better security.
