=== Limited retry and non-violent disablement ===
Modern PALs are believed to feature a limited number of code reentries before the weapon locks out, requiring that the weapon be returned to [[Pantex]] for rebuilding. This system may also include a non-violent disablement system, where some of the weapon's internal components are destroyed to hamper use. This system may be part of the ordinary limited retry lockout system, or may be a feature that can be enabled if the local situation calls for it. The non-violent disablement system may also be part of the weapon's anti-intrusion system, designed to activate if someone tries to enter one of the weapon's exclusion regions such as for the purpose of circumventing the weapon's PAL.<ref>{{cite web | first = Carey | last = Sublette | url = https://nuclearweaponarchive.org/Usa/Weapons/Pal.html | title = Principles of Nuclear Weapons Security and Safety | publisher = Nuclear Weapon Archive | date = 1 October 1997 | access-date = 2021-05-09 }}</ref>
