Access Control Without Full Hardware Replacement

Lock Rekeying in Springfield for homeowners after moving or businesses managing employee key distribution

Rekeying changes who can access your property without the expense of purchasing and installing completely new locksets. The process involves disassembling existing lock cylinders, removing the current pin configuration, and installing new pins that match a different key, rendering all previous keys useless. Allied Lock and Safe provides lock rekeying in Springfield for residential and commercial applications, addressing situations where homeowners inherit unknown key copies from previous occupants or businesses eliminate access after employee departures.


Rekeying works when existing locks function smoothly but key control becomes uncertain, such as after moving into a previously owned home where contractors, realtors, and former owners may have retained keys. The service costs significantly less than replacing functional hardware while providing the same security benefit of exclusive key control.


Schedule rekeying services to establish controlled access immediately after property changes or personnel updates.

Why Rekeying Works for Cost-Effective Security

During rekeying, locksmiths remove the cylinder plug from each lock body, extract spring-loaded pins that correspond to specific key cut depths, and insert replacement pins sized to match a new key code. The process takes minutes per lock once cylinders are accessible and requires no changes to door hardware, strike plates, or installation. Businesses benefit from rekeying multiple locks to match a single master key system, reducing the number of keys employees carry.


After rekeying completes, property owners confirm that old keys no longer turn cylinders, new keys operate smoothly across all rekeyed locks, and key distribution remains documented and limited. Commercial properties notice improved access control when managers track who receives keys and which doors each key opens.


Rekeying applies to most standard pin tumbler locks including deadbolts, keyed handle sets, and commercial cylindrical locks, though damaged cylinders with worn pin chambers or bent housings require replacement instead. The service excludes locks with broken internal components, wafer tumbler mechanisms incompatible with pin replacement, or proprietary keyways requiring manufacturer-specific tools.

What Property Owners Usually Ask

Property owners ask about timing, costs, and situations where rekeying makes sense before scheduling service.

  • What situations call for rekeying rather than lock replacement?

    Rekey when existing locks work properly but key control is uncertain, such as after moving, losing keys, or ending contractor access, but replace locks when cylinders stick, keys require force to turn, or when upgrading to higher-security hardware with additional features.

  • How does rekeying improve security compared to keeping original locks?

    Rekeying eliminates the risk that unknown individuals hold copies of keys cut by previous owners, contractors, or service workers, ensuring that only keys you distribute provide access to the property regardless of how many copies existed before.

  • When is master keying useful for Springfield businesses?

    Master keying benefits businesses with multiple employees and restricted areas, allowing managers to access all doors with a single master key while individual employees receive keys limited to their specific work zones without building-wide access.

  • What determines how many locks should be rekeyed at once?

    Rekey all exterior entry locks simultaneously to prevent gaps in security, and include interior doors protecting sensitive areas, storage rooms, or private offices where key control matters for inventory or confidential material protection.

  • How long do rekeyed locks function before needing service again?

    Rekeyed locks function as long as the original hardware remains in good condition, typically years of reliable use, since the rekeying process replaces only the internal pins and springs without affecting the lock body, cylinder housing, or mechanical operation.
