The Dangers of Duplicate Keys: Why You Should Rekey After Every Move

Moving into a new home is exciting—but it also comes with important responsibilities, especially when it comes to home security. One of the most overlooked (but critical) steps after a move is rekeying your locks. Failing to do so can leave you vulnerable to unauthorized access, theft, or worse.

So, why rekey after moving? Let’s break it down.

The Hidden Risk: Duplicate Keys You Can’t Track

When you take possession of a new home—whether buying or renting—there’s no way to know how many duplicate keys are floating around. Previous homeowners may have shared keys with neighbors, friends, real estate agents, dog walkers, contractors, or cleaning crews. Even if you were handed “all the keys,” there could be hidden copies out there.

These untracked keys mean your home could be accessed by someone you didn’t authorize. That’s a serious home security risk—especially for families or individuals living alone.

Rekeying vs. Replacing Locks: What’s the Difference?

Many people assume they need to replace the entire lock system. In most cases, that’s unnecessary. Rekeying involves changing the internal pins and tumblers of your existing locks so old keys no longer work. It’s faster, more affordable, and just as secure.

Rekeying benefits include:

  • Improved key control
  • No need to replace hardware
  • Compatible with existing doors and finishes
  • Cost-effective peace of mind

When Should You Rekey?

At Dr. Lockaroo, we recommend rekeying your locks under the following situations:

  • Immediately after closing on a new home
  • On or before move-in day, especially if you’re a renter
  • After an eviction or tenant turnover (for landlords)
  • When roommates move out or you’ve lost track of key copies
  • After any break-in or security concern

Proactive rekeying is a simple way to protect your home and loved ones—and it only takes one visit from a professional.
