How to open a combination lock.
Step 1
 Turn combination to the right a few
times, clearing the previous
combinations.
Step 2
 Now, turn the lock to zero.
 This is not going to be your first number.
 If zero is your first number, you can skip to
Step 4.
Step 3
 Now turn the lock to the right, coming to
a stop at your first number.
Step 4
 After turning to your first number, turn to
the left, going past your number once.
 The second time around, come to a stop
at your second number.
Step 5
Now you must turn the combination
to the right once again, to your third
and final number.
Once you have turned to this
number, you can open your lock.
Step 6
 Now that your lock is open, you can get
into your gym clothes (dress out), and
continue getting ready for class.
 If at any time you mess up the
combination or cannot open your lock,
clear the combination by turning the dial
to the right a few times and setting it
back to zero.
Step 7
Now that your locker is open and
you’ve dressed out, put your
clothes into your locker and sit
down while awaiting further
instructions.
