A lock pick is a type of tool that appears in NetHack. It is an unlocking tool that is made of iron.
Samurai know the lock pick as an osaku.
Generation
All Rogues start the game with an uncursed lock pick.
Lock picks make up 3⁄50 of all randomly-generated tools, and are always generated uncursed outside of bones levels and trap "bones". General stores and hardware stores can sell lock picks.
Description
Applying a lock pick towards a door or lockable container will lock it if unlocked, or unlock it if locked, with the chance of the hero succeeding dependent on their dexterity and role: there is a (3*Dex)% chance of success for doors with a +30 bonus for Rogues, and a (4*Dex)% chance for containers with a +25 bonus for Rogues, and the chance of unlocking a container is halved if the key is cursed.[1][2][3]
A hero applying a lock pick to a door in Minetown in view of a watch member has a 1⁄3 chance each turn of being interrupted and warned, causing the door to become trapped as well - immediately attempting to lock or unlock that door again will anger the entire watch.
Intelligent monsters with hands that pick up a lock pick will use it to unlock locked doors, and pets that can use lock picks will hold on to them for this purpose.[4]
The following information pertains to an upcoming version (3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.
Per commit b12ea03d, intelligent monsters will also use lock picks to unlock containers.Strategy
Lock picks are worth carrying for any hero: Rogues using lock picks have comparable odds of success with locking and unlocking doors to a skeleton key for most roles, and it is their fastest method of locking and unlocking containers. they are also the 'heaviest' unlocking tools at 4 aum, though this is not likely to be a factor for any player minus the especially cautious and the highly-efficient packrats.
Most heroes will only need one unlocking tool, though they can keep a backup in case the primary one is stolen or permanently lost. Be careful allowing pets to obtain lock picks, as they will become difficult to keep out of certain rooms (e.g. keeping higher-leveled pets away from shopkeepers and aligned priests).
History
The lock pick first appears alongside other unlocking tools in NetHack 3.0.0.
The ability of monsters to unlock doors using picks and other tools is introduced in NetHack 3.6.0 via commit c1393e50 and commit 74f08dcb.
Variants
Variants based on NetHack 3.4.3 and earlier versions may not add the ability for monsters to unlock doors with lock picks, while variants based on later versions usually retain this feature and allow them to unlock containers as well.
SLASH'EM
In SLASH'EM, non-artifact lock picks that are not blessed have a 1⁄40 chance of breaking for Rogues when applied, and a 1⁄30 chance otherwise.[5][6] This makes it useful for a hero to keep multiple unlocking tools on hand. Monsters cannot use lock picks.
