What’s the Difference Between Lock Rekeying and Lock Replacement?
If you’ve ever moved into a new home, lost a key, or wanted to boost security, you’ve probably heard about rekeying and replacing your locks. But what’s the real difference—and how do you know which one you need?
At Affordable Security Locksmith And Alarm, we walk Phoenix homeowners through this decision every day. Both options improve your security, but each has its purpose. Here’s a simple breakdown.

What Is Lock Rekeying?
Rekeying involves changing the internal pins inside the existing lock cylinder so that the old key no longer works. A new key is made to match the new pin configuration.
You keep your existing hardware, but it now works with a different key.
When to rekey:
- You just moved into a new home
- Someone lost a key
- A roommate or tenant moved out
- You want to reset access without changing hardware
- You want one key to work on multiple doors
✅ Cost-effective
✅ Fast (often done in under an hour)
✅ Maintains the look of your current locks
What Is Lock Replacement?
Replacing a lock means removing the existing lock and installing a brand-new one. This could be a similar model or a full upgrade to a new style, brand, or security level.
When to replace:
- Your current locks are damaged or outdated
- You want to upgrade to smart or high-security locks
- Your style or finish preferences have changed
- You want to install all new hardware with matching keys
- The lock is no longer functioning properly
✅ Ideal for major upgrades
✅ Allows for smart or high-security systems
✅ Gives a fresh, updated appearance

What’s Best for Phoenix Homes?
Phoenix homes face unique challenges—heat, dust, and frequent real estate turnover. Here’s our advice:
Go with rekeying if:
- You just need new keys
- The locks are in good condition
- You want to simplify access across multiple doors
Choose replacement if:
- Your locks are old, rusted, or worn out
- You want better heat-resistant or high-security models
- You’re upgrading to a smart home setup
