Tool: A Phillips screwdriver.
1. Disassemble the lock cylinder sequence: 1Remove the inner and outer handle panels:
The screws are 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 cap in the house, which is 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 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. Second, install the new lock cylinder:
The order is reversed from that when dismantling, there are a few points to pay attention to:1Before 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.
It is normal to change the key when you change the lock cylinder, unless it is exactly the same as the previous lock cylinder.
Check it online, and you can change the lock if you find a regular registration, and the security is also high. >>>More
At that time, I spent money to find someone to change it, and called him to ask him to come and reinstall it; If it's your own, reload it too; The initial diagnosis should be that the lock cylinder is not installed correctly or the lock cylinder model is not suitable.
You can't change it yourself! Can I open the door? It may be that the lock cylinder and lock body do not match! But it depends on the picture (and whether it has been under the lock body).
In terms of anti-theft, neighbors play a great role, and now most of the crimes are committed by teams, relying on tin foil. Door-to-door experiments, people also need efficiency, if you squat in front of someone else's house for half an hour, no matter who will suspect it, if you destroy it, it will startle the snake.
