Absolutely!
I check the rudders before engine start... because, long ago, I managed to get the right engine running before I realized that I left the lock in. That was embarrassing, to have to shut down, get out, and get the lock.
The last thing you should do before getting into the airplane to leave is remove the rudder lock.
Not to mention there is a thing called a preflight we should all be doing. :-). And control check before takeoff?
