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.


Best for:

  • New homeowners who want to ensure old keys don't work
  • Anyone who has lost a key
  • Landlords between tenants
  • Situations where your current locks are in good condition

  • Average cost in Sanford: $25-$45 per lock cylinder


    What Is Lock Replacement?


    Lock replacement means removing the entire lock set — cylinder, knob or handle, deadbolt, strike plate — and installing all-new hardware. Everything is new.


    Best for:

  • Locks that are old, worn, or damaged
  • Upgrading security (e.g., from Grade 3 to Grade 1)
  • Installing a different style or finish
  • Adding a smart lock
  • After a break-in or attempted break-in that damaged the lock

  • Average cost in Sanford: $80-$250 per door depending on hardware selected


    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 Some homeowners rekey the locks they want to keep and replace the ones that are outdated or low-quality.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.


    When to Call a Professional


    While rekeying kits exist for DIY use, improper rekeying can leave your lock partially functional or damage the cylinder — potentially requiring an expensive replacement anyway. Professional rekeying from Daniel Cerda Locksmith costs little more than a DIY kit and comes with the guarantee that the job is done right.
