One of the most common questions homeowners ask us: 'Should I rekey my locks or replace them entirely?' The answer depends on the condition of your locks, your security goals, and your budget. Here's how to decide.
Rekeying changes the internal pin configuration of your existing lock so that old keys no longer work. A locksmith replaces the pins inside the cylinder, and you receive new keys. The lock hardware stays exactly the same — only the key pattern changes.
Lock replacement involves removing the entire lock mechanism and installing a brand new one. This is necessary when your lock is damaged, worn out, or you want to upgrade to a higher security grade or smart lock.
If your locks are Grade 1 or 2, in good working condition, and you simply need to invalidate old keys — rekeying is the smart, cost-effective choice. Moving into a new home? Rekey every exterior lock immediately.
Replace your locks if they are worn, damaged, or a low-security grade. Also replace if you're upgrading to smart locks, adding features like keypad access, or if the current lock brand doesn't have rekey-compatible cylinders.
