One. How to forcefully open a lock when the key is broken.
1、Can I inquire with the property management about authorized locksmiths? If so, I can hire a locksmith to drill a hole in the lockbox using a power drill, then use a tool to pry open the hole and access the locking mechanism. After that, I can use a tool to manipulate the locking pin.
2. A hardwood wedge can be used to create a gap between the door frame and the door. By applying firm pressure with the wedge, the gap is widened, allowing the door latch to disengage from the strike plate on the door frame. Then, a flathead screwdriver or other suitable tool can be used to pry the door open either inward or outward.
3. For round door locks, first loosen the circular disc that is attached to the door, rotating it counter-clockwise to move it back. Then, rotate the disc a few times and align the small hole, and use a small tool to push it firmly. The disc that was loosened can now be removed. After removing the two screws inside, simply pull them out from the outside of the door.
Two. How much does it typically cost to open a lock once?
The price depends on the lock mechanism's structure and the level of urban development. For standard indoor door locks in typical second and third-tier cities, the cost is approximately 50 yuan. For more complex, anti-theft door locks with intricate mechanisms, the price will be higher, around 100 yuan. If the lock mechanism is also replaced, the price will be even higher.
