Rekeying vs. Lock Replacement: Which Is Right for You?

Rekeying vs. Lock Replacement: Which Is Right for You?

Rekeying vs. Lock Replacement: Making the Right Choice

When you want to deny access to old key holders, you have two options: rekey the existing lock or replace it entirely. Each has advantages depending on your situation.

Rekeying: What It Is

Rekeying means disassembling the lock cylinder, removing and replacing the internal pins, and reassembling it with a new key. The lock mechanism stays the same; only the key combination changes. Old keys no longer work.

Lock Replacement: What It Is

Replacement removes the old lock entirely and installs a new lock mechanism. You get new hardware, a new key, and often upgraded security features.

Rekeying: Pros & Cons

  • Pros: Less expensive, fast, maintains existing hardware
  • Cons: Limited security upgrade, locks may be worn

Replacement: Pros & Cons

  • Pros: Modern security, aesthetic upgrade, warranty on new lock, can choose high-security option
  • Cons: More expensive, may require door adjustments

When to Rekey

Just moved in and want to deny previous owners access. Lost a key but the lock is solid. Employee left and you want their key invalid.

When to Replace

Upgrading security, lock is damaged or worn, want smart lock compatibility, aesthetic renovation, concerned about history of the lock.
