How to determine the rotation opening direction of ordinary door locks?

The general rule is that twisting in the opposite direction to the lock position unlocks the lock, and twisting in the same direction closes the lock.

For example, if the lock is on the right side of the door, the right side is the nearest door. Turning to the left, that is, counterclockwise, unlocks the lock. If the lock is on the left side of the door, turn the lock clockwise to unlock it.

In short, it depends on which side it is locked, which way it is turned to lock, and vice versa to unlock.

Door locks, sealers attached to doors, boxes, drawers and other objects, require a special key to open. There are many classifications of door locks, and the requirements for door locks are different in various situations. Ordinary households generally use anti-theft door locks, which are highly secure and relatively cheap; in some high-end places and security agencies, password locks and fingerprint locks are used for security. Very high and expensive; glass doors are used in many public places, so glass door locks are widely used.
