Rekeying vs. Replacing Locks: Which Is Better?

When it comes to securing your home or business, few decisions are as common—and as misunderstood—as whether to rekey or replace your locks.

Both options improve security, but they serve different purposes and vary in cost, convenience, and effectiveness. At Bulldog Locksmithing, our Orlando locksmith experts often help property owners decide which solution fits their needs best. Here’s what you should know before making your choice.

What Does Rekeying Mean?

Rekeying involves changing the internal pins and tumblers inside your existing lock cylinder so that old keys will no longer work. Instead, you receive a new set of keys that match the updated configuration.

Rekeying is ideal if:

  • You’ve lost a key or had one stolen.

  • You’ve moved into a new home or office.

  • You want all your locks to open with a single key.

  • You’re concerned about previous tenants, contractors, or employees having access.

Rekeying keeps your hardware in place but makes your old keys completely useless, offering a fast and affordable way to restore security.

What Does Replacing Locks Mean?

Replacing locks means removing the entire lock mechanism and installing a brand-new one. This option is typically chosen when:

  • Your locks are old, worn, or damaged.

  • You want to upgrade to a higher-security or smart lock system.

  • You’re remodeling or changing the design of your doors.

  • You want a different keyway or lock brand altogether.

While replacing locks costs more than rekeying, it gives you the opportunity to modernize your security and aesthetics at the same time.
