Lockpicks are an excellent tool for gaining access to the contents of locked rooms or chests when one does not have the correct key. These tools are useful to "jimmy" such impedances. However, if the lock is too complex or the door magically sealed, then either a spell or a rare skull key must be employed.
One deficiency these picks have is in their durability; If the user is either too clumsy or attempting to pick an un-pickable lock, the lockpick will break.
In the earliest Ultima games, only guards had lockpicks, then known as keys, meaning the player had to kill them to get access to certain areas. By Ultima III, lockpicks became available from any guild shop, and this would continue until Ultima V; although in that game, lockpicks could be obtained from treasure chests.
- NPCs never seem to object to you jimmying their locks, with the exception being Ultima Underworld II.
