First given in 1918, the Council Key is awarded to a Brother providing meritorious service over a number of years. A jewel is sometimes added to the key if the holder of the Council Key has given continuous service to Pi Lambda Phi of a conspicuous and valuable character. The letters “C.K.” or “H.B.” (Honorable Brother, for those have received the Diamond Chip Council Key) follows the names of those Brothers who have been honored with this award.
