One of the most common questions homeowners ask is whether they should rekey their locks or replace them entirely. Understanding the difference between these two services can save you money while ensuring your home remains secure.

**What is Lock Rekeying?** Rekeying involves changing the internal pins and springs inside your existing lock cylinder so that your old keys no longer work. This process allows you to keep your current locks while gaining fresh security. It's cost-effective, typically ranging from $25-35 per lock, and can be completed quickly by a professional locksmith.

**What is Lock Changing?** Changing locks means completely removing the existing lock hardware and installing new locks. This is necessary when locks are damaged, outdated, or when you want to upgrade to higher security systems. Lock changes cost more ($85-350 per lock) but provide the opportunity to modernize your security.

**When to Choose Rekeying:** Rekey your locks if you've just moved into a new home, lost your keys, had keys stolen, or when contractors, tenants, or ex-partners have had access to your keys. Rekeying is perfect when your locks function properly but you need to revoke access from previous key holders.

**When to Choose Lock Changing:** Replace your locks if they're damaged, worn out, use outdated technology, don't match your new door, or when you want to upgrade to high-security locks, smart locks, or keypad entry systems. Lock changing is also recommended if your locks are old and prone to failure.

**Cost Considerations:** Rekeying is significantly cheaper than changing locks. For a typical Florida home with 5 exterior doors, rekeying costs $125-175 total, while changing all locks could cost $425-1,750 depending on the lock quality chosen. Many locksmiths offer volume discounts for multiple locks.

**Professional Recommendation:** Most locksmiths recommend rekeying for standard security updates and lock changes only when necessary for damage or significant security upgrades. A professional can assess your locks and recommend the most cost-effective solution for your specific situation.
