<h1>Rekeying vs. Replacing Locks: Which Do You Need?</h1><p>One of the most common questions we get is: "Should I rekey my locks or replace them entirely?" The answer depends on your situation, your budget, and the condition of your existing hardware.</p><h2>What Is Rekeying?</h2><p>Rekeying changes the internal pin configuration of your existing lock cylinder so that old keys no longer work. A locksmith removes the cylinder, replaces the pins with a new set, and provides you with new keys — all without touching the lock hardware itself.</p><p><strong>Rekeying is the right choice when:</strong> you've just moved into a new home, you've lost a key, a roommate or contractor no longer needs access, your locks are in good condition, or you want all locks to work on one key.</p><p><strong>Cost:</strong> Typically $20–$50 per lock.</p><h2>What Is Lock Replacement?</h2><p>Lock replacement involves removing the entire lock hardware and installing new hardware in its place.</p><p><strong>Lock replacement is the right choice when:</strong> your locks are old or damaged, you want to upgrade to Grade 1 security, you're switching to a smart lock, the lock has been tampered with, or you want to change the style.</p><p><strong>Cost:</strong> Typically $75–$200+ per lock, including hardware and labor.</p><h2>When You Should Do Both</h2><p>Sometimes the best answer is a combination — replace worn locks with Grade 1 deadbolts and rekey the rest to a single key for convenience.</p><h2>Not Sure What You Need?</h2><p>Give us a call and describe your situation.
