Coded mechanical locks are widely used for safety and closing of access in various spheres. You can put such lock on door, the car, the safe or even the bicycle. Advantage is that it is almost impossible to pick the coded lock in view of availability about 100 million combinations of digits of the code.
Instruction
1. To buy the lock with the code, mechanical or electric, it is possible. Its installation will not take a lot of time too: invite the professional who will establish you him in several minutes and will help to deal with the principle of work. So, to open the mechanical coded lock, remember the following instruction. At you on door or on the safe the four-level mechanical coded lock is put. The code of the lock are four numbers ranging from 0 to 99. The rotating disk of the lock has hundred divisions which correspond to code numbers.
2. Start anew to rotate disk clockwise so that division which corresponds to the first in the code has passed three times by the tag applied on motionless part of the lock. Stop only when this division appears opposite to tag for the fourth time.
3. Further rotate lock disk against the course of hour hand so that division on which the second of the code is applied has passed by tag known to you two times. Stop to rotate disk when division reaches tag for the third time.
4. Now begin to rotate the lock clockwise again so that division of the third in the code has passed by tag once, and, having reached it for the second time, stop.
5. And, at last, turn disk counterclockwise, yet you will not reach the provision of division of the fourth of the code accurately opposite to tag. You watch closely the movements as at one mistake you should repeat everything at first.
6. Carefully turn key in the coded lock. Turn the safe handle (or doors) and open the lock. To close the safe back, turn key in the lock, and turn disk of the mechanical lock on several turns in the direction of hour hand.
