Anonymous users2024-01-23It's a very simple problem, like the chain of the bicycle, the lack of oil, the oil on the oil is good, all the locks that come out are oiled, but the lock cylinder must not be oiled, the lock cylinder can be used with some pencil ends, you can.
You can find a local lock store, they can help you change it, and you can ask about the anti-theft level of their locks, the higher the anti-theft level, the more expensive the price. But you have to bargain, the spread is too high.
The anti-theft performance of the model you said is outdated, it is recommended that you change the lock of the gold point atom, the price is not much higher than that of Wang Li, the anti-theft performance is very good, and it cannot be opened except for smashing the door. It is best to find a regular company to install, and after installation, it should be inspected and the original function is the same].
My family is also Wang Limen
I just changed it a few days ago >>>More
1. The anti-theft door lock is astringent and tight.
When the door lock is astringent, tight and difficult to open, many people know to drip some lubricating oil into the lock, so that the door lock will be smooth and open immediately. However, the oil is easy to stick to the dust, which causes dust to slowly accumulate in the keyhole to form putty, which forms a vicious circle and the door lock is more likely to have problems. >>>More
From my business locks for many years, Wang Limen amplification performance is better, he is with automatic locking function, if from the smoke defeat including unlocking, Buyang door has an advantage, from the point of view of the lock cylinder alone, Wang Liqi Lu has an advantage. Judging from the probability of being bad, Wang Li is more likely to break when he automatically locks the street.
