If you don't need a flashlight, see if there is a foreign object in the keyhole or something, if there is a foreign body taken out, it should be OK. It is easy to use by removing foreign matter.

Otherwise, the lock is completely broken, you can find a lock repair master to take a look, and ask the master to either adjust it or replace a lock cylinder. At critical moments, you have to be a professional.
