How to Fix Broken Window Locks for Better Home Security

A broken window latch leaves your home vulnerable to intruders and energy loss, but you can fix it yourself without replacing the whole unit. Start by identifying whether you have a sashlock, crank, or friction mechanism, then apply silicone spray to lubricate stiff parts or adjust misaligned strike plates to restore proper function. This simple maintenance stops drafts, prevents costly water damage, and turns a weak entry point back into a secure barrier against forced entry.
