How Often Should You Rekey Your Home Locks? A Dover Locksmith Explains

May 28, 2026 · 5 min read · By 1st Capital Locksmith

Most homeowners in Dover never think about rekeying their locks — until something goes wrong. The truth is, your home's security isn't just about having good locks. It's about controlling who has access to those locks. Rekeying is one of the simplest, most affordable ways to reset that control. Here's everything you need to know.

What Does Rekeying Actually Mean?

Rekeying means changing the internal pins inside your lock cylinder so that the old key no longer works. A locksmith replaces the pins with a new configuration that only a new key can open. The lock hardware itself stays the same — you're just resetting which key operates it.

This is different from replacing your locks entirely, which involves new hardware. Rekeying is faster and typically costs much less. Our lock rekeying service can update all the locks in a typical home in under an hour.

7 Situations When You Should Rekey Your Locks

1. You Just Moved Into a New Home

This is the number one reason to rekey. When you move into any home — new construction, resale, or rental — you have no idea how many keys to that home exist. Previous owners, contractors, real estate agents, neighbors with spare keys — the list can be long. Rekeying on move-in day is the single best thing you can do for your new home's security.

2. After a Break-In or Attempted Break-In

If your home was burglarized or someone attempted to break in, rekey or replace your locks immediately. Even if the doors appeared undamaged, a professional burglar can pick or duplicate a key without leaving obvious signs. Don't assume your existing locks are still secure.

3. After a Breakup or Roommate Change

If someone who previously had a key to your home is no longer someone you trust — an ex-partner, a former roommate, a housekeeping service you no longer use — it's time to rekey. Asking for a key back doesn't guarantee there aren't copies. Rekeying eliminates the uncertainty entirely.

4. After Losing a Key

A lost house key is a security liability. You don't know who found it or whether they can identify which door it opens. If your keys were lost in a visible location (your own driveway, a nearby parking lot, at work), rekeying is worth serious consideration.

5. After Hiring Contractors or Service Workers

If you gave a key to a plumber, electrician, house cleaner, or dog walker — even one you trusted — it's good practice to rekey after their work is complete. People change, employment relationships end, and you want to be in control of who can access your home long-term.

6. When Your Locks Are Getting Old

Lock cylinders wear down over time. If your locks are more than 10 years old and you're noticing stiffness, wobble, or the key catching, a rekey won't solve the mechanical issue — that may call for a full lock repair or replacement. But if the hardware is still solid, periodic rekeying keeps the key control up to date.

7. As Part of an Annual Security Review

Security-conscious homeowners in Dover and Kent County treat lock rekeying as routine maintenance — similar to changing smoke detector batteries. An annual or bi-annual check with a residential locksmith ensures your locks are performing correctly and that key control is up to date.

Rekeying vs. Replacing Your Locks — Which Is Right for You?

Rekeying is the right choice when your lock hardware is in good shape and you simply need to reset key access. It's typically 50–70% less expensive than a full lock replacement.

You should consider replacing locks when:

  • The lock is damaged, worn, or doesn't function smoothly
  • You want to upgrade to a higher-security lock brand
  • You're adding a smart lock or keypad entry
  • The lock was forced or tampered with during a break-in

Our residential locksmith team can assess your locks and recommend the most cost-effective solution for your situation.
