iirc, in Arena and Daggerfall, there were two ways to open locked doors. If you were sneaky, you could pick the lock silently, and nearby enemies wouldn't know. OR, if you were strong, you could bash it down with your weapon, but it'd make a lot of noise, and alert nearby enemies. This wasn't in Oblivion, and I dunno about Morrowind. This should be in Skyrim, imo.
