The B key of the Wang Li anti theft door is twisted and the A key cannot be opened, what should I do

The installation of security doors in the home, plus security locks and security door chains are all to ensure the safety of the home. Compared with mechanical locks, everyone should take care of the key and never lock themselves. Recently, some members of the public have locked themselves in their homes because of carelessness.

According to Ms. Liu, a citizen, because she had just moved into her new home for less than a week, she was not very familiar with the external environment, so she wanted to lock the door and take a nap. I didn't expect this lock to go out, but fortunately, my roommate came back to pick up something, and the two of them should work together to open the anti-theft lock. In the process of unlocking, I found that the anti-theft lock had been covered with rust stains, and it was quite laborious to break it up and down, and the plastic handle of the lock was about to break.

In this regard, a staff member of a lock company said that the lock can not be opened when it encounters a fault, so you should first try to use the key to gently open the lock, but do not use brute force to force it open, so as not to increase the difficulty of unlocking the lock after breaking the key. "After trying to unlock with a key to no avail, it is best to contact a regular unlocking company to help unlock the lock; In the daily use of the lock, we should also pay attention to the maintenance and maintenance of the lock, the lock rust and the deformation of the anti-theft door, etc., will affect the normal use of the lock, should be repaired or replaced in time, so as not to aggravate the fault and bring inconvenience to their own entry and exit. A master surnamed Kong of the lock-picking company reminded.

Therefore, for the daily use of locks or anti-leeching chains in the family, because it is a metal lock, if it is not cleaned frequently, it will be beautiful, greatly reducing the service life of the lock. For example, if you always keep the rotating part of the lock body with lubricant, it is recommended to check it once every six months or a year, and at the same time, check whether the fastening screws are loose to ensure tightening.

During the use of the lock, regularly (half a year or one year) or when the key is not smoothly inserted and unplugged, a little graphite powder or pencil powder can be smeared in the lock cylinder groove to ensure that the key is inserted and unplugged smoothly; However, do not add any other oil to lubricate, so as to avoid grease sticking to the bullet and spring, resulting in the lock cannot be rotated and cannot be opened. In addition, always check the matching gap between the lock body and the buckle plate, whether the height of the lock tongue and the gusset hole is appropriate, and the best matching gap between the door and the door frame; If there is a change, the position of the door or the lock plate should be adjusted, and at the same time, pay attention to the thermal expansion and contraction caused by the weather, so as to ensure that the gap between the door and the door frame, the lock body and the lock plate is reasonable, and the lock is used smoothly. The general public is reminded that the metal anti-theft door chains and anti-theft locks used at home must be well maintained.

If there is a situation of anti-locking, first make sure to use the key to open it slowly, if it still doesn't work, don't use brute force, you can find a regular lock company to help.

The cat's eye is unlocked, and the cat's eye is changed to the anti-prying cat's eye after opening.
