This guide will help you understand the difference between rekeying vs changing locks so you can make the best choice.

What is the Difference Between Rekeying and Changing a Lock?

Before diving into which option is better, it’s essential to understand what each process entails.

What Does It Mean to Rekey a Lock?

To rekey a lock is to adjust its internal components to work with a new key. A locksmith rearranges the pin structure inside the cylinder, making the old key useless. This provides enhanced security without replacing the entire lock hardware.

What Does It Mean to Change a Lock?

To change a lock means completely removing the existing lock and replacing it with a new one. This is a comprehensive security upgrade, allowing you to install a different type or brand of lock, such as a high-security deadbolt, to enhance your protection.

Rekeying a Lock: Pros and Cons

Rekeying is a practical choice when security concerns revolve around who has access rather than the lock’s physical integrity.

• Pro – Cost-Effective: Since you keep the existing hardware, the only cost is labor, making it a budget-friendly option.
• Pro – Quick & Convenient: A skilled locksmith can rekey a lock in just a few minutes, quickly restoring your security.
• Pro – Maintains Aesthetics: You keep the same hardware, ensuring a consistent look throughout your property.
• Con – No Physical Upgrade: Rekeying does not improve the lock’s strength or resistance to picking if the hardware is already old or damaged.

Changing a Lock: Pros and Cons

Changing locks is the best option when you need a significant security upgrade or the existing hardware is failing.

• Pro – Enhanced Security: You can upgrade to locks with advanced features, such as smart locks or high-security deadbolts.
• Pro – Solves Hardware Issues: It’s the perfect solution for old, damaged, or jamming locks, ensuring smooth functionality.
• Con – Higher Cost: This option is more expensive as it requires purchasing entirely new hardware in addition to labor.
• Con – Longer Installation: The process can take longer, especially if modifications to the door are needed.

When Should You Rekey a Lock?

Rekeying is the ideal solution in the following scenarios:

• Moving Into a New Property: To ensure previous owners, tenants, or their contacts can no longer gain entry.
• Losing Your Keys: If you are concerned that a lost key may be found and used.
• Employee or Tenant Turnover: To revoke access for former employees, roommates, or contractors.
• Convenience: To key multiple locks alike so that one key opens everything (a master key system).

When Should You Change a Lock?

Lock replacement is the better choice in these situations:

• Damaged or Worn-Out Locks: If locks are old, rusty, or unreliable, they are a security risk.
• After a Break-In: Upgrading to a more secure lock provides better protection and peace of mind.
• Upgrading Security: When you want to install a smart lock, a high-security deadbolt, or a keyless entry system.
• Stolen Keys: If your keys have been stolen (not just lost), changing the lock is the safest measure.

Rekeying vs. Changing Locks: How to Decide

To make the right decision, consider these key factors:

• Key Control vs. Physical Security: Is your primary concern who has a key (rekey), or is the lock itself weak and needs an upgrade (change)?
• Lock Condition: Are your locks in good working order (rekey), or are they rusted, damaged, or jamming (change)?
• Budget: Rekeying is the most budget-friendly option, while changing locks is a larger investment in long-term security.
• Technology Upgrade: If you want to integrate smart technology like keyless entry, you must change the locks.
