What if the lock core of the door lock is broken? What if the door lock won't open?

The lock core is broken and the door won't open. The solution is as follows.

1, the lock core is broken, so we can't open the door. First, we have to find a way to take out the broken lock cylinder. First, unscrew the two screws on the top and bottom of the hand panel, unscrew the screws on both sides of the lock cylinder sleeve, and remove the lock cylinder anti-theft sleeve.

2. Remove the panel. There are two locking nails on the inner panel of the door lock. Note: When taking the screws, don't let the outside fall to the ground to avoid damage.

3. After removing the panel, remove the lock cylinder cover and remove the lock cylinder.

4. Drill a circle of holes in the lock box on the door with an electric drill, then pry open the drilled holes with a screwdriver to directly see the stopper of the safety mechanism inside, and then poke the safety plate with a screwdriver until it is opened.
