What type of lock do I need for a sliding glass door — the latch that came with it doesn't feel very secure?
The factory latch on most sliding glass doors is designed to keep the door closed, not to resist a determined entry attempt — a secondary lock such as a foot bolt, a Charlie bar, or a keyed lock mounted in the track adds meaningful resistance that the original hardware simply doesn't provide. In AZ, sliding glass doors are also exposed to heat expansion and track wear that can make original latches even less reliable over time.
