Automatic Unlocking Device

The Automatic Unlocking Device is an item in Deus Ex: Human Revolution and Deus Ex: The Fall. At first it was only available with the Explosive Mission preorder pack or DLC, but now it is included in the Director's Cut edition.

Background
The AUD uses modified microwave pulse technology, the Keybreaker Security Countermeasure unit can neutralize 98% of conventional electronic and digital locking systems. This one-shot device fires a directed high-energy burst into the circuitry of the security unit, overloading it and forcing an immediate disengage; once activated, the discharge consumes the Keybreaker's internal capacitor and renders the device useless.

Its function as a disposable multi-hacking device makes it a likely technological predecessor to the Multitool.

Characteristics
The AUD is equipped like a grenade and can be used on any device that can be hacked; in order to use one, the player must be close enough for the device's "use" prompt to appear; at this point, a second prompt will appear to press the grenade key or button in order to use the AUD. Using an AUD will automatically defeat the security of the targeted device, even if it exceeds the player's current Hacking: Capture level. The AUD takes a short time to do this, after which it vanishes and the player gains access to whatever it was used on.

AUDs are relatively rare and are one-use items like grenades; they can be bought from merchants, who typically have four in stock, or found within the game's world. They allow players to access code-protected areas with a much lower Capture level than would normally be possible, but do not give the player the items or experience that could be gained by hacking the object they are used on. Another bonus is that AUDs are impossible to throw except in the presence of a valid target, meaning selecting them can be used as a safeguard against accidentally throwing a grenade. It is worth noting that you should not use an AUD in front of a NPC carrying a weapon, as they will become hostile if they see you.

Each 1x1 AUD "stack" in the inventory can contain up to 5 AUDs.
