Such as bicycle locks, home, living room and bedroom doors, padlocks, filing cabinets and drawer locks Step 1 Insert the chuck key into the lock and use the rotary pressure to push the twist tool to pressurize the cylinder. This will keep the shared pens until they are all free step 2 While keeping the latch turned slightly with the key, adjust selection with a rocking motion and use the tip of the calculator to lift the pins one by one up to the shear line step 3 Listen for a click as the cylinder turns slightly forward and insert the next pin. After you put the last pin in place, the connector can turn freely Level 1: padlock The transparent lock is the first lock that you should think of as the first lock. The tolerances are traceable, so finding and adjusting the binding pins is particularly easy. However, this will be an important foundation on which to build any method. Level 2-3: Double Sided Primary Lock This 2 in 1 door leak offers a double challenge, one side is stronger than the other. But this shape of the keyhole is the basic level in the double sided lock, but more difficult than padlocks. You can think of this as a cornerstone for exploring double-sided locks. Level 4: cylinder lock The lock uses a rotary cylinder drive; the door frame can only be retracted when the lock cylinder turns again. It is much more resistant to brute force attack and less sensitive to wedging. You can test the security of your lock by learning to open the locks.
