A programmable keying system (51) for electrical connectors includes keys (56) which are supported within key-receiving passageways (61) in a connector (10) to cooperate with opposing keys in a complementary connector to ensure that the connector (10) will mate only with a connector with which it is intended to mate. The keys (56) are supported in the passageways (61) in a partially inserted, programmable first position in which they are loosely retained in the passageways (61) by first retention means, but are capable of being rotated to a selected orientation. After being oriented, the keys (56) are pushed fully into the passageways (61) to a locked second position in which they are locked in the passageways (61) in the selected orientation by second retention means. The keying system (51) permits connectors (10) to be shipped to a customer with the keys assembled thereto but with the keys unprogrammed such that they can be programmed in the field at a later time.
