What if the lock core of the door lock is broken?

If the lock cylinder is broken, pry it open: 1. First, prepare a cross screwdriver, and use the screwdriver to remove the two screws on the inside of the door, so that the two door handles and guard plates can be removed; 2. Then remove the screw at the lock tongue and pull out the lock core; 3. Buy a new lock cylinder with the same size as the original lock cylinder.
