A deadlock seal was a form of lock, or a device added to a lock, that was almost impregnable. It was more secure than most locks, and appeared to be the only lock the Doctor's sonic screwdriver could not open, besides conventional bolts, and wooden doors. (DW: Silence in the Library, Vampires of Venice, Hungry Earth)

Features

Deadlocking made locks more difficult to open, at least with sonic devices. More sonic devices could be used in concert to break deadlock seals. (DW: Partners in Crime) Additional deadlocking could be applied, from double (DW: Voyage of the Damned) to triple (DW: Partners in Crime, VG: TARDIS).

It was possible to create deadlock seals with a sonic device, as the Doctor "locked" several things during his travels, particularly the controls of his TARDIS, which even the Master could not unlock. (DW:42, Utopia, The Sound of Drums, Last of the Time Lords, SJA: Invasion of the Bane)

Deadlocking did not make glass unbreakable. (DW: The Poison Sky) It did, however, make metal incapable of being melted, or at least heated, and could prevent cords and doors from being separated or opened physically. (DW: The Time of Angels)
