Buyang security door, the door can not be opened with a doorknob, do you know what s going on?

1. First of all, remove the broken doorknob. The door handle of the security door is removed from the inside of the room, because the two screws that fix the handle are inside, as long as the screws are removed. >>>More

I bought Buyang's anti-theft door, the kind that can lock the door with a lift on the door handle, the key can not be opened and turned in, what should I do? >>>More

Don't weld, just replace it with a new set, otherwise others will break it as long as they use a little force, which is not safe.

If the handle is loose with the panel, there are two screws on the panel of the handle on the inside (indoor) of the door, and after finding it, tighten it with a Phillips screwdriver. If the handle is loose or falls off, you need to remove the two screws of the panel and remove the handle, and see that a circlip on the handle is falling off or broken. Take a look at it yourself, if you can't handle it yourself, it is recommended that you find a local lock company to help you repair it.

It can be replaced, and the lock points of the anti-theft door are all holes of uniform size, so the locks are universal. But the protective cover of the key may be slightly different.
