Specific Laws Relating to the Transfer of Objects from One Place to Another on Shabbath, Where There Is No Eiruv
Specific laws relating to the transfer of objects from one place to another on Yom Tov are dealt with in Chapter 19.
MISCELLANEOUS RULES CONCERNING
THE TRANSFER OF OBJECTS
48.a. In the case of keys (as in the case of handkerchiefs), lack of knowledge has led to widespread inadvertent transgressions in the methods of transfer from one reshuth to another, for example by the forbidden practice of simply hanging a key on a belt without its serving any purpose in helping to secure the garment.
48.b. A key may be carried, as part of a belt, in one of the following ways.
1) a) A length of cord or elastic should be passed through the hole of the key and the ends tied (in a bow, but not with an ordinary knot, if it is already Shabbath).
b) The result will be a piece of cord or elastic in the shape of a loop with a key hanging on it.
c) Holding the key in one hand, one should then take the double cord or elastic forming the loop around one’s waist with the other hand, and fasten the “belt” by inserting the teeth of the key in the end of the loop coming around one’s waist from the opposite direction, so that the key serves as a buckle.
2) a) A different method is to tie one end of a cord or elastic to the key (with a bow, if it is Shabbath). key attached to one end.
b) The result is a single length of cord or elastic with a key attached to one end.
c) The single cord or elastic is put around one’s body and the free end is either tied to the teeth of the key with a bow, or wound around them, in such a way that the key serves as an integral part of the “belt,” namely its buckle.
