If you’ve recently moved into a new home, lost a set of keys, or want to refresh your home security, rekeying your locks is one of the smartest and most affordable steps you can take. Armour Locksmith provides professional lock rekeying services throughout St. Louis, MO — fast, clean, and done right the first time.

What Is Lock Rekeying — and How Is It Different From Replacing Locks?

When a locksmith rekeys a lock, they change the internal pins so your old key no longer works and a new key is cut to match. The lock hardware itself stays in place. This is different from replacing locks, which means installing entirely new hardware.

Rekeying is typically the better choice when your existing locks are in good condition and you simply need to ensure that previous key holders can no longer gain access. It’s faster and more affordable than a full lock swap. That said, if your locks are old, worn, or low-quality, upgrading to new hardware — such as a new deadbolt — may be the better long-term investment. Our St. Louis locksmiths are happy to advise you.

When Should You Rekey Your Locks in St. Louis?

  • Moving into a new home: You never know how many copies of the previous owner’s key are out there. Rekeying after a move is the fastest way to know your St. Louis home is secure.
  • Lost or stolen keys: If your keys go missing, rekeying your locks right away removes the risk of unauthorized entry.
  • After a breakup, divorce, or roommate change: Ensure that only current residents hold a key.
  • After a break-in or attempted break-in: Rekeying or upgrading your locks is a critical first step in restoring security.
  • Security upgrade: Want all your locks on one key? Rekeying to a single key setup simplifies daily life and boosts security.
