1.Remove the inner and outer handle panels: Screw on the handle panel in the house, one on the top and one on the bottom.

2.Remove the inner and outer lock cylinder caps: The screws are on the lock cylinder caps in the house, which are the left and right sides of the key.

3.Dismantle the lock cylinder positioning screw: The screw is on the side of the door, in the middle of the deadbolt, at the same height as the lock cylinder. The thickest one is.

4.At this time, the old cylinder can be removed: the old and new cylinders are the same, and they can be replaced.

Install the new lock cylinder:

The order is reversed from when dismantling, and there are a few points to note:

1.Before installing the new lock cylinder, add a small amount of special lubricant to the new lock cylinder. Turn the key several times repeatedly.

2.The lock cylinder positioning screw must be tightened to prevent the screw from loosening and opening the door in the future.

3.Do not tighten the screws of the lock cylinder cap too tightly to prevent screaming and it is not easy to unlock.

4.When installing the inner handle panel, there is a safety bolt underneath, which should be inserted into the corresponding safety bolt hole.

Then we should use a torx screwdriver to unscrew the upper and lower two screws on the top and bottom of the pull handle. Then unscrew the screws on both sides of the lock cylinder anti-theft sleeve, and then remove the lock cap. (Note:.)

Don't tighten the two screws too tightly when installing, and have a sense of activity when pressing the anti-theft shell. Step 2: Remove the lock cylinder anti-theft sleeve.

Note: The same method is used for installation. When you remove the lock cylinder, but you still can't pull the lock cylinder by hand after unscrewing the screws, we have to use a hammer to gently tap around the lock until you take out the old lock cylinder.

Step 3: At this point, the lock cylinder will be completely removed, and now, we have to start installing the new lock cylinder. Start by inserting the safety bolt and then start closing the inner and outer handles, preferably finding someone to hold down the outer handles when closing, which will help you operate.

It is necessary to ensure that the screw holes of the inner and outer handles are aligned before the screws can be rotated. Step 4: When inserting the screws, be sure to insert them vertically, if you don't align the nut inside, gently shake the screw with your fingers, because the screw head is pointed, which has a good feeling and can help you quickly put it on.
