How do you tighten a exterior kwikset lock with no screws?

To tighten an exterior Kwikset lock with no visible screws, you typically need to look for a small access hole on the side of the lock or the thumbturn. Use a flathead screwdriver or a small tool to insert into the hole and turn it, which will adjust the tension of the lock cylinder. If the lock has a set screw hidden beneath the thumbturn, you may need to remove that component to access and tighten it. Always ensure the lock is functioning properly after making adjustments.
