Lock M points

Locks a door or container by M points. The effect is permament until an Open spell is cast on it, or it is picked or opened with a key.

[edit] Notes

There are only a few practical uses for this spell. First, you can use it to practice your Security skill, by repeatedly locking and picking the same lock. Note that lockpicking is considered a crime, even on a container that is not owned by anyone and never locked by default. Thus you should try to do this only where there are no potential witnesses. (Other than people following you, who don't seem to mind.)

Containers that you Lock and unlock will permanently carry the "unlocked" notice on them.

You can also use it to flee pursuers or to keep out potential witnesses from a room if you plan to commit a crime there (theft or murder). This is only applicable on interior doors, not doors which go into a different cell, as NPCs in Morrowind are incapable of using doors which go into a different cell. (Unless they are following you, in which case they come with you immediately, and can't be locked out.) Since NPCs are incapable of picking locks and not smart enough to cast an Open spell, a very weak Lock spell (even 1 point) is just as effective as a stronger one for this purpose, and much easier to cast.
