My google-fu is strong tonight. (Plus I remembered which TV station had the feature.)
Zip ties to open trap:
To get the trap to open you have to squeeze down the spring holding it shut. If you have strong hand muscles, no problem.
If not, put a zip tie on the spring, squeeze it down as much as you can, tighten the zip tie so it stays down, take a breath, squeeze it a little more and tighten the zip, eventually you'll have it squeezed down enough you can put the 'safety' on and lock it open and remove your pets head, paw, body whaterver from the trap.
He also shows how to use a rope to do it which might be more useful because you could probably substitue shoe laces or a drawstring from a jacket for the rope.
