Directions for Use

The ShurLok operates on a patented system of two groups of combinations. One combination opens the shackle (factory setting on 0-0-0-0) and the second combination opens the sliding key storage door (factory setting on 3-3-3-3). To set your combination at any time, follow the instructions below.
  1. Set dials to shackle combination (new lock comes with factory setting on 0-0-0-0). Dials must be set to current shackle code in order to make any combination changes. Open shackle (to insure you are on the correct shackle combination).
  2. Use a paper clip, small screwdriver or dime to turn the change screw button located above the key compartment. Turn the screw clockwise 90 degrees (1/4 turn). Never force the change screw. If it is difficult to turn - STOP - make sure the numbers are lined up and that you have the correct combination for the shackle, not the key door.
  3. Turn the dials to the numbers of the new shackle combination that you have selected. Record your new combination in a safe place. The sliding door combination is automatically set when the new shackle combination is set. Follow the chart below to find the new combination for the sliding door.
  4. Return the change screw to the original position by turning counter-clockwise 90 degrees (1/4 turn). Open & close shackle. Dial in the new key door combination & open & close key door. Your ShurLok is now re-set.
  5. If you wish to have the key compartment combination be a specific number, then use the chart below to determine what the shackle combination would be. That is the number that you would reset on the lock. You do not set the combination of the key compartment.

NOTE: Some locks are stiff being new. If the lock will not open the first time, simply press down on the dials to settle them in place.
