Need your locks rekeyed or changed quickly? Alliance Locksmiths provides same-day residential and commercial rekeying, serving Westchester since 2003. Licensed, insured, and trusted by thousands of homeowners, landlords & property managers.

Rekeying is the fastest, most cost-effective way to secure your property when:

  • You’ve moved into a new home
  • A tenant moved out
  • Keys were lost or not returned
  • A contractor or previous owner still has copies
  • You want multiple doors keyed alike

We change the internal pins of your existing lock so old keys stop working—without replacing the hardware unless needed.

When a Full Lock Change Is Better than Rekeying

A full lock replacement is recommended if:

  • The existing lock is damaged
  • The lock hardware is extremely old
  • You're ready to upgrade to a higher-security lock
  • You want keyless or smart-entry options

We carry standard and high-security hardware for residential & commercial properties.

  • How long does rekeying take?

    Most jobs take 20–45 minutes, depending on how many locks you need rekeyed.

  • Is rekeying safer than changing the lock?

    Yes—rekeying changes the key access without replacing hardware. It’s a cost-effective security reset.

  • Can you make all my doors use one single key?

    Yes. We can rekey multiple locks to match one key, as long as the hardware is compatible.

  • Do you offer emergency rekeying?

    Absolutely. Same-day and emergency service is available 7 days a week.

  • Do you service apartments and multi-family buildings?

    Yes. We work with landlords, HOAs, and property managers across Westchester.
