This term originated in the military and meant that your M-16 had the magazine in place and was ready to fire. The order to "lock and load" means to get ready for action.
If you are "locked and loaded," it means you are ready for whatever comes next.
The term was in use before the M-16. Many western stories and movies have used the saying for rifles as well as for wagons. It also has been used as an old sailing term for the storage of goods being locked into place and loaded aboard.

Locked and cocked is a term usually associated with a firearm, although it is usually said "Cocked and Locked". This refers to arming the firearm, that is the gun has a bullet chambered and the hammer is cocked and the gun will fire if the trigger is pulled. Locked means the safety is engaged. Cocked, locked and ready to rock is a longer version of the phrase. It just means you are ready. You are fully prepared to do what needs to be done.
