🔐 Rekeying vs. Replacing Locks: What Homeowners Should Know
When it comes to securing your home, you might wonder whether you should rekey your locks or replace them entirely. Both options serve the purpose of improving security, but they differ significantly in cost, effort, and application.
✅ What is Rekeying?
Rekeying involves changing the internal components (tumblers or pins) of a lock so that it works with a new key and no longer accepts the old one. The lock hardware remains the same.
Pros of Rekeying
- Cost-effective: Cheaper than replacing the entire lock.
- Quick security update: Ideal after moving into a new home or losing a key.
- Keeps existing hardware: No need to alter your doors or handles.
- Key convenience: Multiple locks can be rekeyed to work with a single key.
Best For
- New homeowners
- Lost or stolen keys
- Wanting one key for multiple locks (if they’re compatible)
- Tenant turnover in rental properties
🔁 What is Replacing Locks?
Replacing involves removing the entire lock mechanism and installing a new one, often with a different style or security level.
Pros of Replacing
- Upgraded security: Allows for smart locks, deadbolts, or high-security options.
- Style & finish update: Customize the look of your hardware.
- Repair damaged locks: Necessary if the current lock is broken or worn out.
Best For
- Outdated or malfunctioning locks
- Upgrading to smart locks or keyless systems
- Home renovations or remodels
- When you want different keys for different doors
