          At present, the mechanical lock of rolling shutter door is the product with the lowest frequency of use in the door products, and it is not one of the products. Because it is not used for a long time, it will lead to the appearance of the lock rust, stuck and other phenomena, resulting in the rolling shutter door key can not be inserted, turned, pulled out and other problems. Then, once this phenomenon is encountered, how to solve it?
          First of all, it is necessary to analyze the causes of the failure of the mechanical lock of the rolling shutter door, and carefully observe it, in order to find an effective solution. We can analyze them one by one.
          1. There are soil and other faults in the lock cylinder: because the lock cylinder of the rolling shutter door is at the bottom and very close to the ground, usually walking, wind blowing, rain and so on may cause dust and soil to enter the lock cylinder. At this time, if there is soil in the lock cylinder, do not rush to insert the key, use pins, toothpicks and other tools to clean the soil in the lock cylinder, and then use volatile lubricating oil to lubricate, and use solid lubricant after drying Lubricant graphite lubrication, be sure to regularly check and clean up debris.

          2. There are foreign matters in the lock cylinder: more than 80% of the foreign matters in the lock cylinder are pranks or deliberate retaliation, and the bamboo stick and glue are artificially poured into the lock cylinder. In this case, the key can not be inserted. If it is toothpick, bamboo stick and other foreign matters, you can try to pick them out with a pin. If you can't buckle them out, you can only change the lock violently. If it is glue pouring, you must change the lock.
          3. Long time disuse leads to lock rusting: This is the most common phenomenon. First of all, lubrication is necessary, and solid lubricant is used. Use children's pencil lead powder, sprinkle it on the key, insert it into the lock core and rotate it repeatedly, so that the graphite powder is evenly distributed. At this time, you will feel that the key is very smooth in and out.
          If the key has been inserted, can't turn, can't pull out, at this time we have to recall in detail what actions have been done to insert the key. Generally, this phenomenon is caused by the key inserted reversely, the check is not in place and so on. After slightly turning the key, the key hole is locked, and the key can't move. At this time, we just need to operate according to the opposite action of the original action, that is, to reset the key to the just inserted position Adjust the key depth or add lubricant.
          At this time, the key can be used normally. However, this is only a low-level error; most of the time, it's like this: if the key is not fully inserted and can't be turned by half a turn, if you find that the key is not inserted in place, you can continue to insert it and continue to turn the key, and then it's stuck; or if you insert the key and can't turn it by half a turn, you're ready to pull it out.
