A blind lift rod control lock includes a housing having an axle hole, a rotating member revolvably mounted in the axle hole of the housing, the rotating member having a non-circular through hole, which receives a lift rod for enabling the rotating member to be synchronously rotated with the lift rod, a reverse ratchet, and a forward ratchet, and a locking mechanism. The locking mechanism has a follower member, a first hooked portion adapted to engage the reverse ratchet, and a second hooked portion adapted to engage the forward ratchet. The follower member is selectively controlled to force the first hooked portion into engagement with the reverse ratchet or the second hooked portion into engagement with the forward ratchet.
