The fire door lock is relatively easy to disassemble in the door lock, as long as there is a tool, the fixing screw is now unscrewed to remove the lock cylinder, and then unscrew the screw to remove the panel, and then the side screw can be disassembled. The components of the fireproof door lock are mainly fixed by screws, and the fireproof door lock can be removed as long as the fixed screws are removed.
Question: What should I do if the fixing plate is disassembled and the lock cylinder cannot be taken out.
Answer: If the lock cylinder is too astringent to be withdrawn, you can add some engine oil, lead foam or vegetable oil to the lock body to increase its lubrication, so that it can be pulled out of the lock body. However, if the paddle in the lock cylinder is not in place, then you need to insert the key into the lock body to return it to its position, and the lock cylinder can be pulled out.
