When to Rekey vs. Replace Your House Locks—A Locksmith’s Advice in Mount Vernon

Keeping your home secure starts with the locks on your doors. But when something changes—like losing a key or moving into a new place—you may wonder: should you rekey your locks or completely replace them? Both options improve security, but knowing the difference can save you time and money.

For homeowners in Mount Vernon and nearby areas, L & J Keysmith-Locksmith helps families choose the right solution for their situation. Here’s our expert advice to guide you.

What Does It Mean to Rekey a Lock?

Rekeying means changing the internal pins inside your existing lock so the old keys no longer work. You keep the same lock hardware, but you receive new keys that match the updated pins.

Best times to rekey your locks in Mount Vernon:

• You’ve moved into a new Mount Vernon home and don’t know who still has a copy of the old keys.

• You lost a key but the lock itself is still in good condition.

• You want all your doors to open with one key for convenience.

• You recently had a roommate or tenant move out.

• You’re on a budget but still need to improve security.

Rekeying is usually faster and more affordable than a full replacement, making it a popular choice for many local homeowners.

When Should You Replace Your Locks?

Replacing a lock means removing the entire hardware—like the knob, lever, or deadbolt—and installing a brand-new lockset.

Situations where replacement makes sense in Mount Vernon homes:

• Your lock is damaged, rusted, or outdated.

• You want to upgrade to high-security or smart locks for better protection.

• You’ve experienced a break-in or attempted break-in.

• The lock no longer functions smoothly, even after cleaning or lubrication.

• You’re renovating and want a new style or finish to match your doors.

While replacing locks costs more than rekeying, it can add extra security features, modern looks, and long-term reliability.
