Anonymous users2024-01-24The door closes loudly: 1The door is deformed, caused by the impact of the door leaf and the door frame, and the treatment method:
Adjust the hinge or find the impact and knock it flat with a hammer. 2.The lock is used for a long time to cause oxidation, and the deadbolt collides with the keyhole
Solid lubricating oil is applied to the deadbolt. The handle rotates loudly: the internal parts are oxidized due to long-term use, and the rotating bearing is not smooth
Liquid lubricating oil is dripped into the bearing and soaked (usually within 3 days).
No, Wang Li's lock has an invention patent, and it is generally only installed on Wang Li's anti-theft door.
My family has been using Wang Li to prevent and leak the door, Wang Limen is the first brand in China's door industry. Good quality!! The after-sales service is also very considerate!! I bought it at the Hailstorm and the service was very welcoming. It is a recommended product of the Public Security Bureau. >>>More
As long as the cylinder is the same! You can remove the original one and go to the place where the lock is sold.
That's right. If you have a key, it is very unsafe. It's better to change the lock cylinder, and there is protection.
OK. Wang Li is famous. It's because of his locks that he is famous. Go to the Wang Li store or lock the city and ask.
