Keyed Alike: Have the same key for multiple locks

A keyed alike lock system means multiple locks are configured to be opened with the same key. Instead of juggling several keys for different doors, one key operates all designated locks. This setup is commonly used for front doors, back doors, garage access doors, and side entries, making everyday access easier while keeping your home secure.

The biggest advantage of keyed alike locks is convenience. One key reduces clutter on your keyring and makes access simpler for families, guests, or trades. It’s also ideal for households where multiple doors are used daily, ensuring quick entry without searching for the right key. For many homeowners, it’s a practical upgrade that improves day-to-day living.

Keyed alike locks are most commonly used on external doors within the same property. Front, rear, garage, and laundry doors can all be matched to one key for seamless access. They’re especially useful in new builds and full renovations, where all hardware is being installed at the same time, allowing for a consistent and coordinated locking solution across the home.

While keyed alike locks use one key for multiple doors, keyed to differ locks each require a unique key. Keyed to differ options may suit homes where certain areas need restricted access, but for most residential applications, keyed alike offers greater ease of use. Choosing between the two comes down to how you want to balance convenience, access control, and personal preference.

When selecting keyed alike locks, it’s important to order all required locks at the same time to ensure they can be matched correctly. Not all lock types or brands can be keyed alike, so checking compatibility is essential. It’s also worth considering future needs, adding another door later may require re-keying or replacing hardware to maintain the same key across all locks.
