Rekeying vs. Replacing Your Locks: Which Is Right for You?
One of the most common questions we hear from homeowners in Sanford, FL is: "Should I rekey my locks or replace them entirely?" Both accomplish the same primary goal — ensuring that old keys no longer work — but they do so very differently, at different price points, with different benefits.
What Is Rekeying?
Rekeying involves changing the internal components of your existing lock (the pins and springs inside the cylinder) so that only a new key will operate it. The lock hardware — the knob, deadbolt, and strike plate — stay exactly as they are. Only the internal configuration changes.

The Quick Decision Guide
| Situation | Recommendation |
|-----------|----------------|
| Just moved into a new home | Rekeying (usually sufficient and cost-effective) |
| Lost your keys | Rekeying |
| Old, worn, or stiff locks | Replacement |
| Want to add smart lock features | Replacement |
| After a break-in | Replacement (and security upgrade) |
| Want all locks on one key | Rekeying |
| Lock damaged or picked | Replacement |
Can You Do Both?
Absolutely. Some homeowners rekey the locks they want to keep and replace the ones that are outdated or low-quality. This is often the smartest approach for a comprehensive security refresh.
