Elioth's Minor Rejection

When cast on an inorganic opening (keyhole, mouse hole, torch sconce, scabbard, etc.) less than roughly 6 inches square, the opening will reject any item that would otherwise pass through the opening for one day. The result is that the object, no matter the weight, is thrown 1d6ft directly away from the opening. The resulting throw does no damage. This effectively makes the opening invisibly impassible unless the spell is dispelled. If cast at the same time 5 days in a row, the spell is permanent unless dispelled.

If desired, the spell can be cast on multiple openings within a 60' radius by adding 10 minutes for each opening affected.
