How to Lubricate Locks and Door Hinges

Schlage smart locks may blink green but not open due to incorrect installation, enabled lock override, dirt/grime, low or dead batteries, or minor technical glitches. The article provides five fixes: verify correct installation and alignment, check and toggle the lock override, replace AAA alkaline batteries (avoid mixing or rechargeable batteries), clean and lightly lubricate the lock and strike plate, and perform a factory reset if electronics fail. After a reset, all codes and settings are erased and must be reprogrammed. Additional tips include testing default codes and consulting model-specific guides if problems persist.
