Rekeying vs. Replacing Your Locks: What’s Best?

When it comes to protecting your home or business, the security of your locks plays a crucial role. But what happens if you lose your keys, move into a new property, or simply want to upgrade your security? The two main options are rekeying your existing locks or replacing them entirely. Both have their advantages—so how do you decide which is best for your situation?

What Is Rekeying a Lock?

Rekeying means adjusting the internal pins of your existing lock so that old keys will no longer work. A locksmith provides you with a new key while keeping the same lock hardware in place.

Pros of Rekeying:

• Cost-effective – Less expensive than replacing locks.

• Quick solution – Can be done in a short time by a professional locksmith.

• Keeps existing hardware – Perfect if you like the look and function of your current locks.

• Great for key control – Ideal if you’ve lost keys, had a tenant move out, or need to restrict access.

Cons of Rekeying:

• No hardware upgrade – If your locks are outdated or damaged, rekeying won’t fix that.

• Limited to current lock quality – Security level remains the same as the original lock.

What Is Lock Replacement?

Replacing involves removing the entire lock and installing a brand-new one. This gives you a fresh start with both new hardware and keys.

Pros of Replacing Locks:

• Security upgrade – Opportunity to install high-security locks or smart locks.

• Fixes worn-out hardware – Best choice if your current locks are old or damaged.

• Style update – Choose new finishes or designs to match your doors.

• Increased durability – Modern locks may provide stronger resistance against tampering.

Cons of Replacing Locks:

• Higher cost – More expensive than rekeying.

• More time-consuming – Installation takes longer, especially if multiple locks are being replaced.

When to Rekey vs. Replace

• Rekey if:

  • You’ve lost a key but your lock is still in good condition.

  • You’ve moved into a new home or office and want to ensure old keys don’t work.

  • You want multiple locks to work on one key (keying alike).

• Replace if:

  • Your locks are old, rusty, or damaged.

  • You want to upgrade to smart locks, high-security locks, or different styles.

  • You’re renovating and want a fresh look for your hardware.
