Should You Rekey or Replace Your Locks in Miami Beach?

US Locksmith is a licensed (Lic #00443LK) locksmith company serving all of South Florida since 2004. The choice between rekeying and replacing your locks in Miami Beach depends on the lock's condition, your security goals, and your budget. Rekeying is faster and cheaper when the hardware works fine; full replacement is the right call when locks are worn, damaged, or outdated.

What Is the Difference Between Rekeying and Replacing?

Rekeying changes the internal pins of your existing lock so a new key works and the old one does not. The lock body stays in place. Replacing means removing the entire lock and installing new hardware. Rekeying costs $20 to $50 per lock; replacement runs $100 to $300 per lock including hardware and labor.

Rekeying is an internal change only. A locksmith removes the lock cylinder, swaps the pin configuration to match a new key, and reinstalls the cylinder. The process takes about 15 minutes per lock. Replacement involves removing the old hardware completely, fitting new locksets, and testing alignment, usually 30 to 45 minutes per door.

When Should You Rekey Instead of Replace?

Rekey your locks when the hardware is in good condition but you need a new key — after moving into a new home, losing a key, ending a roommate arrangement, or dismissing an employee who had access. Rekeying is also the right choice when you want all locks in your home to work with a single key.

Miami Beach condos frequently change tenants. Rekeying between tenants is standard practice because the lock hardware is usually recent and functional. It saves the condo association money while ensuring previous tenants cannot access the unit.

When Should You Replace Instead of Rekey?

Replace your locks when the hardware is visibly worn, corroded, loose, or more than 10 years old. Miami Beach's salt air accelerates corrosion — locks near the ocean often need replacement sooner than inland hardware. Also replace when upgrading from standard to high-security or smart locks.

Signs a lock needs replacement: the key turns but the bolt does not extend fully, the lock wobbles in the door, the finish is pitted or rusted, or the lock is a builder-grade model installed when the home was built. Upgrading to a Grade 1 or high-security lock is an investment in long-term protection.

Can You Rekey a Lock Yourself?

DIY rekeying kits exist for common brands like Kwikset and Schlage, but they require precision. A misplaced pin means the key will not turn. For Miami Beach homeowners who are comfortable with detailed mechanical work, a DIY kit costs $10 to $25. For everyone else, a professional rekey at $20 to $50 per lock is faster and guaranteed.
