A fastener is disclosed. The fastener includes a housing, a cage, one or more retaining members, and a plunger. The housing defines a housing cavity. The housing cavity includes a recess. The cage is disposed at least partially in the housing cavity. The cage includes a cage cavity and one or more passages in the cage aligned with the recess. The one or more retaining members are retained within the one or more passages. The plunger is movable in the ball cage cavity between a first position to cause the one or more balls to be displaced outwardly relative the one or more passages to seat the one or more retaining members in the recess thereby mechanically locking the housing to the ball cage, and a second position thereby allowing the one or more retaining members to be displaced radially inwardly relative the one or more passages to cause the one or more retaining members to be unseated from the recess.
