The numbers are in the outer Cache container and after a quick inspection you should be able to figure it out, Trust your Geosenses.
The 1st number of the combination is "A"
The 2nd number of the combination is "X"
The 3rd number of the combination is "Y"
Once you have these 3 values you can then open the lock and sign in.
When done please return everything the way that you found it so that the nest person can have fun with it too, and do not forget to reset the lock to wrong numbers
