Question 2: How to take out the lock when the key is stuck in the keyhole requires frequent lubrication and maintenance, otherwise the key will be difficult to open, rust, or even twist the key, or the internal lock block will be stuck and cannot be opened.
Well-known lock factories such as Eiskola mostly use fully synthetic lock lubricants from Tiger hotolube or Krupp kluber. Fully synthetic base oil production, clear and transparent, colorless and tasteless, low temperature resistance, dust-free. Tao Bao has a 30 ml small oil bottle with a sharp mouth. Just drop a few drops, which is very convenient to use. The maintenance period is six months.
Mineral oil can't be used, because mineral oil has high viscosity and is easy to be contaminated with dust. It is also not suitable for pencil powder or black graphite lubrication, which can not lubricate internal parts, and there will be heavy metal and color pollution.
Question 3: The key is broken in the lock. How can I take it out? You can use pliers to fold the front end of the needle into a small hook, then use it to go in along the keyhole and hook out the broken key. Very clever. Wish you success!
Question 4: How to break the key when it gets stuck in the keyhole? If the teeth are all in the hole, it is not easy to take them out. Most of them are broken when they are not easy to drive. First, put some oil in the jar. Knock with something for a while. Take a screwdriver with the same width. It is best to insert through the keyhole, not too hard. As long as you can twist the lock core, turn it left and right, and then turn it in the opening direction. It is smooth.
If it really doesn't work, find a lock opener.

Question 6: The door was open and the key was broken in the keyhole. How to take out the lock cylinder door without screws? If a little bit is exposed, you can clip it out with needle-nosed pliers.
If it doesn't show, you can find a thin saw blade or iron piece to reach in and take out the broken key. Or take a big steel needle, bend the needle tip slightly (try it with your fingers, it will feel like burr), then insert it into the keyhole, and slowly break the gap between the broken key and the keyhole, so that the burr of the needle tip faces the broken key, and the hand holding the needle should not exert any external force, so that the needle tip burr can hook the broken key, and then gently pull it out of the keyhole, and the broken key will be taken out immediately.
If it doesn't work, find a lock opener, usually anyone with a key will.
Question 7: How to pull the key out of the lock hole? Find a paper clip, straighten it, make a small hook at one end with pliers, insert this thing from the back of the key to a certain depth, pull it out to take out the broken key in the keyhole, and take the key of the security door in the broken keyhole in this way.

Question 10: The key is broken in the lock hole. How to take out this lock core? I think you have removed the four big screws that hold the lock. Now you turn the door lock to the open position, and the upper and lower connectors will retract. Then remove the pin from the connecting rod with needle-nosed pliers, and pay attention to the fact that the connecting rod above should be wrapped or stuck with tape to prevent it from falling. After all the pins on the upper and lower connecting rods are removed, the lock can be unlocked. There is an iron plate behind the lock. If you want to remove the lock core, you must first remove the iron plate with a trowel. After removing the iron plate, you will naturally see two screws that fix the lock cylinder. Congratulations on removing those two small screws. The lock core can be removed.
Note: this kind of lock is called "automatic lock" and there are several springs in it. If it is not professional maintenance, it is best not to disassemble it. It's not that it can't be disassembled, but it may not be put back after disassembly. The lock core is installed at the wrong angle and the door can't be opened.
I suggest you don't dismantle it yourself, just dismantle the lock and take it to a professional lock shop master to help you install it. Normally, we don't accept this money.
I hope my answer is helpful to you. Any problem of "lock" can be solved. Li * Wen * locks the city.
