Rekey vs. Replace a Lock: Which Do You Actually Need?

When your keys are lost, stolen, or just in too many hands, you have two options: rekey the lock or replace it entirely. They solve the same core problem — old keys no longer work — but they differ in cost, effort, and when each makes sense. Questions? Call Macon Locksmith GA at (478) 382-5517.

What Rekeying Actually Is

Rekeying changes the internal pins of your existing lock so the old key no longer works and a new key does. The lock hardware stays exactly where it is. It typically takes 10–20 minutes per lock.

What Replacing Means

Replacing means removing the entire lock hardware and installing brand-new locks — new keys by default, but you’re paying for new hardware plus installation labor.

When Rekeying Is the Right Call

• You just moved. The #1 reason Macon homeowners rekey — you don’t know how many copies of the old keys exist. (See our lock rekeying service.)
• You lost a key. If a stranger could find it, rekeying neutralizes it.
• A roommate or tenant moved out. Standard practice for rentals across Macon-Bibb County.
• Your locks are in good shape. If the hardware is solid, there’s no reason to replace it.

When Replacement Makes More Sense

• The lock is damaged or worn out. A loose, sticky, or corroded lock won’t be fixed by new pins.
• You want an upgrade — e.g. to a smart lock with a keypad.
• Mismatched brands and finishes, and you want one key for everything plus a consistent look.
• Very old hardware — some historic Macon homes have mortise locks that can’t be rekeyed in the modern sense.

The Cost Difference

Rekeying is almost always cheaper — labor plus a few dollars in pins and key blanks, not new hardware. If budget matters and your locks are fine, rekey first and upgrade later. Tip: having all doors keyed alike (one key opens everything) is usually included — ask for it.

Can You Rekey a Lock Yourself?

Rekey kits exist, but they’re brand-specific and fiddly — one mis-seated pin means the lock fails, or worse, still works with the old key. For most people, having a residential locksmith do it in one visit is worth it for the certainty.

Frequently Asked Questions

How long does rekeying take?

About 10–20 minutes per lock. A whole house (4–6 exterior locks) is typically done in about an hour.

Will rekeying work on any lock?

Most modern pin-tumbler locks, yes — Kwikset, Schlage, and similar brands common in Macon homes. Some high-security locks and very old mortise locks are exceptions.

Do I get new keys with rekeying?

Yes — old keys stop working and you get fresh ones. Ask for copies while the locksmith is there; key duplication on the spot is cheapest.

Should I rekey after a break-in attempt?

Yes, especially if keys were taken or you can’t account for all copies. Consider whether damaged hardware should be upgraded too.

Rekeying vs. replacing for a rental property?

Rekey between tenants, every time. It’s inexpensive, fast, and the industry standard. Replace only when hardware is failing.

Can all my locks use the same key?

Usually yes, if they’re the same brand/keyway family. Ask to have everything keyed alike — a routine request.

The Bottom Line

Lost control of your keys? Rekey. Hardware failing or want an upgrade? Replace. For the most common situation — a move, a lost key, a tenant change — rekeying is the faster, cheaper, correct answer.
