Rekey vs. Replace: Choosing the Right Lock Solution for Your Home

When it comes to home security in Arizona, one of the most common questions homeowners face is: Should I rekey or replace my locks? It’s not just about cost - it’s about safety, convenience, and making the smart call for your home. If you're searching for a locksmith in Chandler, this guide will help you make the right decision.

Understanding the Basics

What’s the Difference?

Rekeying involves adjusting the internal pins of your existing lock so that a new key works and the old one no longer does. The hardware stays in place—only the key changes.

Replacing means removing your current locks entirely and installing brand-new ones with a different key system.

When to Rekey Your Locks

Rekeying is ideal when:

  • You’ve just moved into a new home in Chandler.
  • You’ve lost a spare key but don’t believe it’s been stolen.
  • You want to use a single key for multiple locks.
  • You’re a landlord and a tenant has moved out.

Advantages

  • More affordable than replacement.
  • Quick service—often completed in one visit.
  • Keeps existing hardware (great if it matches your home’s look).

Disadvantages

  • Won’t resolve worn-out or faulty locks.
  • Limited if you’re upgrading to smart or high-security systems.

When to Replace Your Locks

Consider lock replacement if:

  • Your locks are damaged, rusted, or outdated.
  • You want to switch to a different style (keypad, smart lock, etc.).
  • Your home was recently broken into or an attempted break-in occurred.
  • You’re upgrading to high-security hardware like ANSI Grade 1 deadbolts.

Advantages

  • Total upgrade in security and appearance.
  • Modern styles can increase home value.
  • Enhances curb appeal.

Disadvantages

  • Higher upfront cost.
  • Installation may take longer, especially for multiple doors.
