To change entry knob cylinders, simply insert the
master/control key and rotate it 1/4th turn counterclockwise to the 9:00
...and pull gently. The cylinder will follow the
key out of the knob.
Then, simply insert the master/control key into the new cylinder
and rotate the key 1/4th turn counterclockwise. Slide the new
cylinder into the knob and turn the master/control key 1/4th
turn clockwise to the
12:00 o'clock position and remove
the master/control key.
The cylinder change is now complete! After practice,
typical time to perform this
task is less than 5 seconds.
