Deadlock seal

A deadlock seal is a form of lock. A deadlock seal is more secure than most locks, so secure that even a sonic screwdriver cannot open one. The Krillitanes invading Earth in 2007 used deadlock seals, as did the Bane in 2008 and the Humans responsible for the manufacture of cargo ships for that reason. Adipose Industries Hq could be deadlocked, this included doors and windows, this form of lock can be activated in a second, the computer built into the Adipose Industries Hq building (The Inducer) was said to be triple deadlocked.
