@Bennosuke:

If Orla fails her Security roll (you might give her a +10 bonus from Milo helping or easy/basic lock etc), Marc'll cast 'Weapon Jinx'. It says 'scramble circuitry' and 'all mechanical devices' in its description (electrical and mechanical engineers reading this are going nuts atm) so it's your call if dysregulating the electronic lock makes it reset or turn off long enough that it can be opened:

Weapon Jinx
You reach into nearby machines with your mind to scramble their circuitry. All mechanical devices within range cease to function for 1 Round. In addition you may Test Willpower to force a single weapon within range to jam. The jammed weapon can be cleared as normal. Note that the Adeptus Mechanicus are especially loathing of this kind of ability and tend to take a very dim view of Pyskers that employ it.
