Is a door chain lock worth adding to my front door, and can a locksmith install one properly so it actually holds?
A door chain provides a secondary layer of control that lets you crack the door without fully opening it — but only if it's mounted into solid framing, not just the door casing, which is where most DIY installations fail. Sundial Locksmith anchors chain locks into structural material so the hardware can withstand real force, not just casual contact. Call (480) 525-7778 and we'll install it so it works when it matters.
