Wang Li s old anti theft door wants to change the lock cylinder, how to remove the lock cylinder

A Phillips-head screwdriver.

Cylinder anti-theft lock.

1.Change the lock (whole).

Remove the original place, don't think about it, you can screw it when you see it, and I don't need to teach you how to screw it; I counted and just 20 small parts were removed.

2.The first one to be installed is the largest fast part A, a bit like a hard disk thing, there are many mechanisms inside, we don't need to understand, just pay attention to the upper and lower two ticks B. Looking inside from the cross-section, there are two shaking things inside, one on the top and one on the bottom, each with an opening, and the two hooks of this A must be hung into the two openings, so that the upper and lower door locks can be controlled through linkage.

3.Next is the previous cuboid, just insert it directly, and twist it to control the deadbolt in and out.

4.Put the lock cylinder in, put the lock cylinder in, and then you can use the key to try whether you can open the lock and lock it. There is generally nothing wrong with that. Parts E1 and E2 are paired, cover the lock cylinder D, put two screws on it, and fix the lock cylinder.

On both sides of the doorknob, the doorknob is also paired C1 mouth to align with part C, twist to control the deadbolt, and fix it with two screws after closing.

5.The upper side baffle, this is simple, press it, the deadbolt can handle normally, the position is correct, and it is locked with screws. Succeed with flying colors.

Find a locksmith, this lock is not good, and it is not good to be safe.

A screwdriver, a vise, and you're done.
