One of the most common questions we get is: should I rekey my locks or replace them entirely? The answer depends on a few key factors.
What Is Rekeying?
Rekeying changes the internal pin tumbler configuration of your lock so that old keys no longer work. The lock body, knob, and deadbolt hardware all stay the same — only the cylinder internals change. It's faster and cheaper than replacement.
When to Rekey
Rekey when: - You just moved into a new home or apartment - You lost your keys and want to make old copies invalid - An employee or roommate left and you want to prevent their key from working - Your existing locks are in good condition and you're happy with the brand
When to Replace
Replace when: - Your existing locks are old, worn, or difficult to operate - You want to upgrade to a higher security grade (e.g., Grade 1 deadbolt) - Your lock was damaged in a break-in attempt - You want to change the look or finish of your hardware
Cost Comparison
Rekeying typically costs $20–$35 per lock. Full replacement with a new Schlage or Kwikset deadbolt runs $75–$150+ depending on hardware. For most new homeowners, rekeying is the smart, budget-friendly choice.
