Using the Shurlok

Your combination for the shackle can be used as a padlock or just to secure the ShurLok at a location. You keep the combination for the shackle...

...and give the combination for the key compartment to the individual you want to share the key with.
That person accesses the key compartment (not the shackle) with the combination you gave them

After sliding the door up to the key compartment they then retrieve the key.
