SCHLAGE FE575 HAS BROKEN SPRING ON INSIDE HANDLE

Strange that an internal door has one of those!

No, you will need a locksmith or some way to get in the room another way (window, cut a hole in drywall). Or you spring the door jambs apart and slip the lock. Sometimes you can remove the hinge pins. Or drill the key lock out with a Carbide Drill. It is a $95 lock.

Change your battery out using a quality brand battery IMMEDIATELY! Flashing red means the battery is critically low, and the lock may quit functioning altogether! Don't get locked out!
