Rekey vs. Replace Locks: Understanding the Difference

Rekeying Locks Cost and Benefits

  • Cost-Effective Solution: Rekeying is generally less expensive than replacing locks. When you rekey, you only pay for the labor and new keys rather than purchasing entirely new locksets. This can result in significant savings, especially if you have multiple locks to update.
  • Enhanced Security: Rekeying ensures that any previous keys no longer work, providing peace of mind that only you and authorized individuals have access to your property. This is particularly important if you’ve lost your keys, recently moved in, or experienced a security breach.
  • Convenience: If you have multiple locks, rekeying allows you to have them all operate with a single key. This simplifies key management and reduces the number of keys you need to carry. It’s especially convenient for businesses or properties with multiple entry points.
  • Quick and Easy Process: Rekeying is a relatively quick process that a professional locksmith can complete in a short amount of time. Rekeying is straightforward and minimally invasive, unlike replacing locks, which might involve more extensive labor and modifications to doors.

Lock Replacement Pros and Cons

  • New Lock Installation: While rekeying modifies the existing locks, replacing them involves installing brand-new lock hardware. This might be necessary if your current locks are outdated or damaged beyond repair.
  • Security Upgrade: Installing new locks can be part of a broader security upgrade, such as switching to high-security locks or smart locks for better control and monitoring.
  • Higher Cost: Lock replacement typically costs more than rekeying because you’re paying for both the new hardware and the installation labor.
  • Time-Consuming: The process of replacing locks can take longer, especially if you need multiple locks changed or if the installation requires adjustments to the door.

When to Rekey

  • New Homeowners: One of the first things new homeowners should do is rekey their locks. This ensures that previous owners, real estate agents, or anyone else with a copy of the old keys cannot access your home.
  • Lost or Stolen Keys: If your keys have been lost or stolen, rekeying your locks immediately is crucial to prevent unauthorized access. This proactive step ensures that anyone who might have found or taken your keys cannot enter your property.
  • After a Break-In: In the unfortunate event of a break-in, rekeying your locks is an essential step in restoring your home’s security. Even if the intruder did not use a key to gain access, rekeying ensures that any compromised keys are rendered useless.
  • Tenant Changes: For landlords and property managers, rekeying locks between tenants is a smart practice. This guarantees that former tenants no longer have access and provides new occupants with the assurance of secure locks.

The Rekeying Process

During the rekeying process, a locksmith will:

  1. Disassemble the Lock: The lock is taken apart to access the internal pins and springs.
  2. Replace the Pins: The old pins are removed and replaced with new ones that match a new key.
  3. Reassemble the Lock: The lock is reassembled and tested with the new key to ensure it works smoothly.

Rekeying Advantages

  • Key Control: Rekeying improves key control by ensuring that only new keys can operate the lock, eliminating the risk associated with lost or duplicated keys.
  • Affordable Lock Solutions: By rekeying instead of replacing, you save money while still enhancing your security.
  • Home Security Options: Rekeying provides an effective security measure without the need for a complete lock overhaul, making it a practical choice for many homeowners.
