Lock Rekeying vs. Replacing
What Is Lock Rekeying?
Rekeying a lock involves changing the internal pins of a lock cylinder so that old keys no longer work. The physical lock remains intact, but new keys are issued to operate the lock. Key points about rekeying:
- Cost-effective compared to full replacement
- Quick process, often completed within minutes
- Maintains existing hardware and aesthetics
- Ideal for situations where keys are lost, stolen, or after moving into a new property.
What Is Lock Replacement?
Replacing locks means removing the entire lock hardware and installing a brand-new lock. This option is often chosen when locks are damaged, outdated, or when upgrading to higher-security systems. Key points about replacing locks:
- Provides new hardware for enhanced security
- Allows for upgraded or modern lock designs
- Necessary if locks are broken or non-functional
- Ideal for older homes with worn locks or commercial properties with high-security needs.
Differences Between Lock Rekeying vs Replacing
| Feature | Rekeying | Replacing |
| Cost | Lower, often 50–70% cheaper than replacement | Higher, includes hardware and installation costs |
| Time | Quick (usually under 30 minutes per lock) | Longer, depends on type and number of locks |
| Hardware | Existing lock remains | Entire lock replaced with new hardware |
| Security Upgrade | Limited to changing key access | Can upgrade to high-security or smart locks |

Which Option Is Best?
The best option between rekeying and replacing your locks depends on your needs. Rekeying can be great when you need to change your keys without replacing your lock. However, lock replacement may be the best option if your lock is outdated or damaged.

Understanding more scenarios where rekeying and replacement are the best options can help you make a more informed decision.
