Rekeying vs. Replacing Locks: What Your Residential Locksmith Wants You to Know

When it comes to securing your home, most homeowners face an important decision: should you rekey your locks or replace them entirely? While both options aim to improve security, they serve different purposes and come with unique advantages.

At Locksmith Ninja Perth, we believe that informed decisions lead to safer homes. If you’re unsure which option is right for you, here’s what your trusted residential locksmith wants you to know about rekeying vs. replacing locks.

What is Rekeying?

Rekeying involves altering the internal components (pins and tumblers) of your existing lock so that it works with a new key. The old key will no longer work, but the lock itself remains in place.

Rekeying is typically quicker and more affordable than a full replacement. It’s an ideal solution when you’re happy with your current locks but need to restrict access to previous key holders.

What is Lock Replacement?

Lock replacement, on the other hand, means completely removing the existing lock and installing a brand-new one. This might be a simple like-for-like swap or a full upgrade to a different type or higher-security model.

Replacing your locks allows for more flexibility in choosing upgraded security features like smart locks, keyless entry, or anti-drill mechanisms—making it ideal for homeowners looking to enhance safety.

When to Rekey Your Locks

Rekeying is a great choice in the following situations:

  • You’ve just moved into a new home and want to ensure previous owners, tenants, or contractors no longer have access.
  • You’ve lost a key, and you’re worried someone may find it and use it.
  • You want all your locks to work with a single key (if the locks are compatible).
  • You’re on a budget, and your current locks are in good working condition.

At Locksmith Ninja Perth, we offer quick and affordable rekeying services across Perth, giving you peace of mind without replacing your entire locking system.

When to Replace Your Locks

Sometimes, rekeying isn’t enough. Consider replacing your locks if:

  • Your current locks are old, worn out, or damaged.
  • You want to upgrade to high-security locks or smart locks for added protection and convenience.
  • Your lock has been tampered with or is no longer functioning properly.
  • You want to change the style or finish of your hardware for aesthetic reasons.

Our team at Locksmith Ninja Perth can help you choose the perfect replacement locks for your home—ensuring maximum protection and durability.

Cost Considerations

Generally speaking, rekeying is more affordable than replacing locks, since you’re only changing the internal mechanism. However, it doesn’t provide the same opportunity to upgrade your hardware or security level.

Replacing locks costs more upfront but can be a smart long-term investment in your home’s safety—especially if your current locks are outdated or compromised.

Our locksmiths at Locksmith Ninja Perth are happy to provide transparent pricing and expert recommendations based on your unique situation and security goals.

Final Thoughts: What’s Right for You?

The decision to rekey or replace your locks depends on your current security concerns, the condition of your hardware, and your budget. Both services offer unique benefits—and the good news is that a professional residential locksmith can guide you toward the right solution.

Whether you choose to rekey or replace, you’ll be taking a proactive step toward better home security.
