i know this is a bit late but im having the same problem. You didnt happen to have the skeleton key did you? (I posted this on your other post too)
The skill should still level up with the Skeleton Key. Try asking a lockpicking trainer such as the ones at the Thieves Guild to train a bit; perhaps this will jump-start the leveling.

i already have the skeleton key and the lockpicking skill is not leveling
thanks but i already tried it it's already at max level
What? That doesn't make sense. Do you mean your lockpicking level is maxed out or the trainer is? The Trainer shouldn't be, but if they are, then you may want to try going to the Thieve's Guild and lockpicking all of those practice chests.
yeah it's already legendary
Then you can make it legendary again; of course you can't increase the level past 100.
