Common Failures And Remedy Of Padlocks

Safety padlock is used most often in daily life. Because the parts are enclosed in the lock body and do not need to be installed during use, it rarely fails. Padlocks that have been used outdoors for a long time will have failures such as lock core and lock beam not jumping.

1.The lock does not turn

The failure of the locked heart not turning often occurs in a padlock that has been locked outside the door for a long time and is not opened frequently. The padlock has been exposed to wind and rain for a long time, rust and dirt accumulated between the lock core and the lock body, and the lock core cannot be rotated.

Before troubleshooting, check carefully whether the key you hold is the key of the lock, and then remove the fault after confirming it.

The method of elimination is to pour in a little diesel or gasoline, wait a while, insert the key, and try to open. If it cannot be opened, add some diesel or gasoline, soak it for a while, use the key to gently turn it back and forth until it is fully opened. Never use too much force to break the key.

In addition, the lock core may not turn due to damage to the key teeth. At this time, you should carefully look for the damaged part of the teeth. If the damage is small, you can still unlock it after repair; if the damage is large, you should find another spare key to unlock.

2.The key is not flexible

The key is not flexible when used for a long time. You can sprinkle some pencil powder {graphite} in the keyhole, and then switch it several times. Never add engine oil to the keyhole for lubrication. This will affect the movement of the marbles and cause unexpected opening failures.

3.Lock the beam without jumping

The failure of the lock beam not to jump is mostly caused by the excessive tolerance of the lock beam shape and position. The locking beam and the hole of the lock beam appear scratching on one side, and the rust and accumulated dirt make the lock beam unable to jump.

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

4.The key breaks into the lock body

The key breakage into the lock body fault occurs frequently, and the troubleshooting method should be based on the breakage situation.

The key is broken into the lock body from the root, and a section is left in the lock hole. It can be clamped out with tweezers or needle-nose pliers.

The key breaks into the lock core from the middle and cannot be shaken out. In this case, the only way to remove the seven-hole seal on the lock body is to shake out the pin and take out the lock core and the broken key together, then re-install the lock core and the pin and seal it with aluminum wire.
