Wang Li brand anti theft door lock key can not be imported

The lock cylinder is broken! It is recommended to take a few more keys and try to add some vegetable oil to the lock cylinder, but only to change the lock cylinder.

Try to change a spare key, I have encountered this situation a few times, and the door is opened when I change a key that has not been demagnetized.

Hello, this is a good solution. There are three methods, one is to scrape some pencil powder with a knife yourself, sprinkle it on the key, and then insert it into the keyhole to let the powder enter the lock cylinder. Two kinds of hardware store or binary store to buy "sewing machine oil", must be this oil other can not, this is great, not easy to insert the key, the door is not easy to hit, just a little lower. >>>More

Are the Wang Li anti-theft doors you are talking about the one with automatic gear locks? Or other styles, the key can be pulled out after the reverse lock, unless there is a problem with the lock cylinder or lock body that cannot be pulled out.

Spray the keyhole with rust remover! Hardware stores sell a bottle for ten yuan and can be used for a long time.
