Dreaming of repairing the security door, the more you fix it, the more faults there are

You can directly find the manufacturer to repair the password lock, and it will generally be guided by phone or repaired at home.

Oh That's not necessarily, as long as the lock cylinder is turned by someone else, no matter how many lock points of the security door are, it is useless! The anti-theft door lock point can only be said to be better anti-vandal, but then again, the thief will pry the door relatively less, and the anti-theft door will be pry for a long time The sound is loud, and the general thief seems to use the universal key to open the anti-theft door, and the general lock can be done within tens of seconds or 5 minutes! >>>More

Thickness is one thing, but also depends on the anti-theft level of the lock cylinder; Generally speaking, the thicker the door, the stronger the anti-theft force, but few people will be stupid to break the door into the door to steal, the door anti-theft mainly depends on the lock cylinder level, the higher the level, the better the anti-theft performance!

If it's summer, it's normal.

The reason is: there is a layer of rubber pad on the door side in the middle of the anti-theft door, this layer of rubber pad will have a proper expansion in the summer, so it will be a little difficult to close, if the new door has just left the factory, there will be such a problem, this is what I learned with the technician of the dragon armor, hehehe, now learn to sell it, hehehe. >>>More

You first look at what is the sound, if the hinge is a little lubricating oil, it may be that there is something dirty inside, in that case, it is washed down with water first, it is also possible that the rubber strip is loose, whether it is squeezed into the rubber strip, the hinge is loose, the gap between the door leaf is small, and it is possible to squeeze the rubber strip There will be a sound, it is chirping, and the hinge should be gurgling.
