The most common cause of door rattles is a striker plate that is worn, loose, or misaligned, but other potential causes include loose door handles, window winder handles, door hinges, or door stays, as well as loose, worn, or misaligned door lock components, a loose or worn remote control mechanism, and loose window glass. If the striker catch is worn due to door rattles, it is advisable to fit a new striker before making any adjustments to the door. In cases where door hinges are significantly worn, new hinges should be installed.
