What happened when the anti theft door lock key turned inside many times before it was opened?

It should be caused by serious wear and tear of the lock cylinder, and the best solution is to replace the lock cylinder.

Anti-theft door lock troubleshooting

1.The key is not flexible in connection with the replacement.

The key is not very flexible after being used for a long time. You can sprinkle some pencil powder inside the keyhole and turn it on and off a few times. Do not add oil lubrication to the keyhole, as this will affect the movement of the pin and cause unexpected opening failures.

2.The anti-theft lock beam does not jump.

Insert the key into the lock core, turn it to the open position and do not move, and gently tap the lock body down with a small hammer or pull down the lock body firmly. If the shock does not open, you can add a little gasoline or diesel fuel to the lock beam, and then gently knock until the lock beam jumps out. After the lock beam jumps out, use a soft hammer to correct the lock beam, and it can continue to be used after repair.

3.The key is broken into the lock body.

The key is broken into the lock body from the root, and a section is left at the lock heart. It can be pinched out with tweezers or with tools such as needle-nose pliers. The key is broken into the lock core from the middle and cannot be shaken out.

In this case, the only way to do this is to disassemble the seven-hole cover on the lock body, shake out the lock core and the broken key together, and then reload the lock core and the bullet and seal it with aluminum wire.

The most common composite type lock on the market is a combination of a bullet lock and a magnetic lock, which professionals call a magnetic composite lock. To open this kind of lock, you must first destroy the magnetic properties of the lock, and then you can technically unlock the lock.

Because your anti-theft door lock key is idling, when the key is not inserted in place or the blade does not fall into the slot, it is always idling, only after it is in place will it really exercise the function of the key to twist the deadbolt

Mr. Zhang'You go for a walk, oh, exaggerate.

Pro, there can be three answers from the pro question, the first answer is that the pro anti-theft door lock key is idling, when the key is not inserted in place or the blade does not fall into the slot, it is always idling, only after it is in place will it really exercise the function of the key to twist the deadbolt and open the door. This is normal. Judging by this, it should be like this.

This should be a little problem with the key or blade, or the pro key is not in place. The second answer is that the door is locked (both the oblique tongue and the square tongue are extended), so it does take a few turns to open it, because the first circle turns the square tongue, and then the two oblique tongues need to turn the key. Third answer:

It may be that there is a problem with the coordination between the lock cylinder cam and the lock body, that is, the cam (or it may be the gear) can not hook the lock body transmission device, so of course the lock cylinder cannot be turned when you twist the lock cylinder.

To sum up, the first pro is the most likely, the second is the best to judge, and the third is very unlikely, unless the pro's lock body is really... It's been used for too long.

Pro, if you need to choose a good anti-theft lock cylinder, you can consider me doing (mai) by the Chinese lock industry expert committee supervised production of Saidian brand super B-level idling blade anti-theft door lock nuclear envy to change the core Oh, anti-technology open, anti-interruption pie, anti-violence, very cost-effective. You can lock the industry by Junda.

I don't know if my pro is satisfied?
